Abstract - Cloud computing is one of the latest Information Technology innovation phenomena that
has risen from the idea of sharing, consolidating, and standardizing of resources in a centralized
infrastructure and facility. This concept offers many advantages such as cost reduction in both
hardware and software investment for organizations. Despite these advantages, cloud computing
adoption among organizations is relatively slow with a low adoption rate. As such, this study
attempts to bridge the gap by offering insight into possible factors that could influence such
adoption decisions. By integrating the Diffusion of Innovation Theory (DOI) and IT personnel
characteristics, a conceptual model is developed and tested as a preliminary study to determine the
influencing factors of cloud computing adoption by the Malaysian public sector to enhance its
service delivery. The results revealed that relative advantage, compatibility, and IT personnel
knowledge are the innovation attributes and the human factor for cloud computing adoption in the
Malaysian public sector. This study contributes to the knowledge domain of cloud computing
adoption literature on theories of IT adoption particularly in the public sector.

1. Introduction
Governments around the world are struggling to deliver more efficient and effective public
services in order to meet the increasing demands and expectations of citizens and dealing
with the main problem of decreased public resources and financing at the same time. In the
prior literature, it is widely accepted that an electronic government (e-Government) is
much more complex than any previous efforts of IT that have brought changes to the
public sector. Therefore, the incorporation of new or latest information technologies in the
e-Government domain poses a challenging task due to several factors such as the
interoperability of applications and systems (Cellary and Strykowski, 2009), the variability
of its target stakeholders, the bureaucratic political influence, and the slow rate of adoption
(Wyld, 2009).
The emergence of the cloud computing technology has opened up new possibilities for
many governments. Cloud computing is one of the latest IT innovation phenomena that has

risen from the idea of sharing, consolidating, and standardizing of resources in a
centralized infrastructure and facility. This concept offers many advantages such as cost
reduction in both hardware and software investment for the organization. Cloud computing
technology is now of significant relevance for many different domains of e-Government
and there are well-known examples of its uses in enabling the idea of a connected
government (Shin, 2013; Wyld, 2009). In the literature, the number of studies emerging on
the factors that influence the adoption of cloud computing on various private sector
domains ranging from large organizations to small medium businesses (SME) are
increasing (Carcary et al., 2013; Gupta et al., 2013; Opitz et al., 2012). However, there is a
lack of empirical studies focusing on cloud computing domain and its application adoption
in the context of e-Government especially at federal, state, and local government levels. In
addition, the few studies that exist in this domain lack theoretical underpinning and the
backing of empirical research.
Cloud computing is an innovative IT solution used to operate business applications over
the Internet technology, just like online banking, electronic commerce, and electronic mail.
The cloud computing environment is about not having any more expensive, capital-
intensive hardware and infrastructure, and time-consuming, staff-intensive upgrades
(Buyya et al., 2011; Buyya et al., 2009; Dhar, 2012). Its exclusive feature, such as pay-as-
you-go, enables organizations’ finance, human resources, sales, or service applications
through a web browser. In the literature, the definition of cloud computing varies across
fields of study in business and technical domains (Buyya et al., 2011; Buyya et al., 2009;
Dhar, 2012; Mirashe and Kalyankar, 2010). Cloud computing is defined as a model for
providing on-demand access to computing services via the Internet. The services offered
by cloud computing include infrastructure as a service (data centre and server facilities),
platform as a service (operating systems), and application as a service (business packages,
e.g. Enterprise Resource Planning, Accounting Systems Planning, and Microsoft Office
package). Internet technology is the medium used as the transport mechanism between the
client and the services (servers or applications) located anywhere in cyberspace, as
compared to having this service residing on an “on premise” computer. Another literature
defines cloud computing as a means of renting IT infrastructure such as computers,
storage, and network capacity on an hourly basis from an organization that has these
resources and services in its own data centre and is able to make them available to
organizations and customers via the Internet (Issa et al., 2010). This style of computing is
where massive, scalable IT-related capabilities are provided as a service across the Internet
to multiple external customers. This solution can be interpreted as the illusion of infinite
computing resources available on demand, the elimination of top-front commitments by
cloud users, and the ability to pay for the use of cloud computing resources on a short-term
basis as needed (Buyya et al., 2011).
There are now governments across Europe and Asia that have benefited from the cloud
computing technology and the adoption is increasing (Wyld, 2010). The United States of
America, United Kingdom, and Japan are examples where cloud computing has played a
major role in the governments’ transformation, especially in IT strategy and operations.
The ultimate aim for governments to adopt cloud computing is due to the fact that the
cloud computing innovation can stimulate e-government initiatives by using the “cloud-
government” or c-government innovation (Zhang and Chen, 2010). Research is also being
carried out to design the system architecture for the c-government to integrate
heterogeneous e-government into a generic and large-scale government cloud framework.
According to the Asia Cloud Readiness Index 2014 produced by the Asia Cloud
Computing Association (2014), Malaysia is ranked number eight (8) behind other Asian

developing countries such as Japan, Australia, South Korea, New Zealand, Hong Kong,
Taiwan, and its neighbor, Singapore. The weakest indicators for Malaysia’s readiness
index are Broadband Quality, Business Efficiency Index, Global Risk, ICT Development,
International Connectivity, Data Protection Policy, and Government Prioritization.
In the context of the Malaysian government, cloud computing is a new concept and to
benefit from cloud computing assimilation, it will require a lot of success factor research
before it can be accepted and adopted. The Malaysian Administrative Modernization and
Management Planning Unit (MAMPU) is the main player and the lead agency in the
Malaysian public sector to play this role. The fact is that the present ICT systems and
infrastructures work wonderfully well on a stand-alone and silo basis for the federal and
state government organizations. The adoption of new technologies requires some legacy
systems in the public sector to be replaced while new systems and the existing compatible
systems need to be integrated. However, the IT personnel realize that there are some
pressing issues in IT that deserve serious attention. To exploit the advantages of the cloud
computing technology, the IT personnel in the Malaysian public sector should gradually
incorporate this innovation into their information systems’ processes to support the e-
Government.
Therefore, this study is concerned about identifying the problems that are hindering the
adoption of cloud computing technology in the Malaysian context and about deriving an
integrated information system theory model that can be used by other organizations. Thus,
the central aim of this study is to identify and examine the determinants of cloud
computing characteristics and IT personnel characteristics in the cloud-based services
adoption in the Malaysian public sector. This study aims to contribute to the emerging
field, specifically by focusing on the following research questions: (a) what is the
relationship between cloud computing technological factors on the propensity to adopt
cloud-based services in the Malaysian public sector?; and (b) what is the relationship
between IT personnel’s characteristics on the propensity to adopt cloud-based services in
the Malaysian public sector?
2. Literature Review
The Diffusion of Innovation Theory is derived from the exertion of Everett Rogers (1995)
and is frequently used to explain technology innovation especially ICT acceptance and
adoption studies. Rogers' DOI theory focuses on the spread of innovation (ideas, processes,
and technologies) over time among the members of a social system (Rogers, 1983, 1995a,
2002). The members of the social system are the adopters, who can be an individual, a
group, or an organization (Rogers, 1995). Rogers' concepts of diffusion include the adopter
categories, S-shaped curve, and the adoption predictors.
According to Rogers (1995), there are five categories of adopters in the DOI theory: (1)
innovators - the first individuals to adopt an innovation. They are generally young, willing
to take risks, have great financial fluidity, are very sociable, have the closest contact with
scientific sources, and interact with other innovators; (2) early adopters - the second
category of adopters to adopt an innovation. The characteristics of these adopters are
similar to those of the innovators; (3) early majority - adopters in this category adopt an
innovation after a varying degree of time, but it is significantly longer than the innovators
and early adopters. In addition, adopters in this category usually have above average social

33
status and have contact with early adopters; (4) late majority - adopters in this category
will adopt an innovation with a high level of skepticism and after the majority of a society
has already adopted the innovation. They usually have below average social status and
very little financial fluidity; and (5) laggards - adopters in this category are the last to adopt
an innovation. Adopters in this category tend to focus on traditions, have the lowest social
status, lowest financial fluidity, and are the oldest of all the adopters.
Moreover, the DOI theory is also widely used to find adoption predictors of lT diffusion in
organizations (Frambach, 1993; Hameed et al., 2012; Lee, 2003; Oliveira and Martins,
2011; Zhu et al., 2006). According to Rogers (1995), there are three groups of adoption
predictors: individual (leader) characteristics (individual innovativeness), internal factors,
which consist of firm characteristics (business size, business age, available resources,
organizational slack, and how ICT is used and managed), and external factors of the
organization. Rogers (1995b) also emphasized the impact of technological characteristics,
namely relative advantage, compatibility, complexity, trialability, and observability on
potential adopters.
However, the technological characteristics focus on the primary objective features of the
technology itself (cloud computing technology), rather than the subjective features in the
mind of the decision maker in the Malaysian public sector such as the IT personnel.
Therefore, the researchers have conceptualized the innovation attributes relationship with
the propensity to implement cloud computing in the Malaysian public sector together with
IT personnel characteristics. Based on the theoretical background information and the
review of findings in the literature, this study proposes a two dimensional model, which
incorporates the variables of human and innovation factors in understanding the decision to
implement cloud computing in the Malaysian public sector. Therefore, this study
determines that these two dimensions will affect the Malaysian public sector’s decision on
the adoption of cloud computing technology in a positive manner.
2.1. Relative Advantage
Relative advantage is viewed as an advantage for an organization over previous ways of
performing the same task (Alam, 2007; Moore and Benbasat, 1991). Relative advantage
has been found to be one of the best predictors and is positively related to the innovation
adoption rate (Alam et al., 2011; Borgman et al., 2013; Rogers, 1995b). Borgman et al.
(2013) in their study using European respondents found that relative advantage of cloud
computing was positively linked to cloud computing adoption within the convenience of
the capital expenditure. However, the other concept for relative advantage is based on the
technological features that are offered which include simplicity of business process
(communication, coordination, and mobilization). However, the confidence level will be
low if the organizations do not have experience or are relatively new to cloud computing
systems (Buyya et al., 2009). In view of the advantages that cloud computing offers, it
would be expected that the Malaysian public sector which perceives cloud computing as
advantageous would likely adopt cloud computing thus enhancing the e-Government
service delivery to the stakeholders. Thus, it is hypothesized that:
H1: Relative advantage has a direct influence on the propensity to adopt cloud-based
services in the Malaysian public sector
Sallehudin et al.

2.2. Compatibility
An innovation that is perceived to be in tandem with the organizations’ work behavior,
values, experience, and practice or compatibility will experience a high rate of adoption
(Rogers, 1995b). Compatibility of the technological innovation with an incumbent system
or technology can either speed up or retard its rate of adoption in the organization.
Compatibility of the innovation can be measured by the degree to which the innovation
meets the client’s needs. Organizations should determine the requirement to fulfill their
clients or customers’ needs, then recommend the adoption of innovation (Alam et al.,
2011). The adoption rate will be faster and higher when the innovation is compatible with
these needs. However, if the innovation is irrelevant to the needs, it may not be adopted
even though the innovation can provide better performance and services in accomplishing
a given task (Alam et al., 2011). Cloud computing compatibility within the Malaysian
public sector is expected to influence the adoption more positively because most of the
incumbent systems and technology infrastructures are based on the famous and known
technology solutions such as Microsoft, Linux, Oracle, Cisco, etc. This technology is a
vendor supported cloud computing compatibility. Thus, it is hypothesized that:
H2: Compatibility has a direct influence on the propensity to adopt cloud-based services in
the Malaysian public sector
2.3. Complexity
Complexity of innovation is measured as the degree to which cloud computing innovation
is perceived as being relatively difficult to understand and use. One of the barriers to
innovation is the complexity of the innovation to be understood and used. Cloud
computing is a new business solution model with a high complexity. Cloud computing,
contains three different levels of models such as Infrastructure as a Service (IaaS),
Platform as a Service (Paas), and Software as a Service (SaaS). Therefore, the business
model needs to be carefully analyzed and designed in order to identify the proper, suitable
dimensions and facts, and the hierarchies at each of these levels. Besides, cloud computing
also offers four different deployment models (private, community, public, and hybrid
cloud) to choose from. An inadequate choice can have a major effect on the performance
of the entire system especially in e-government systems. In the context of this study, the
complexity of the cloud computing influences the adoption of cloud-based services in the
Malaysian public sector. Thus, it is hypothesized that:
H3: Complexity has a direct influence on the propensity to adopt cloud-based services in
the Malaysian public sector
2.4. Trialability
Trialability refers to the extent that organizations perceive their ability to try, test, or
experiment with a cloud computing platform with limited scale and full specification
before making a decision on whether to adopt it. An innovation to be adopted must be
tested with “proof of concepts” (POC) to fulfill the customers’ requirements which might
increase the intention of future adoption. In the Malaysian public sector context, POC is
the way in which organizations evaluate, test, and measure the degree of suitability and
compatibility of new innovation to the incumbent systems, infrastructure, and
environment. Triability or POC has become the mandatory requirement for any new ICT
Sallehudin et al.

35
project adoption in the Malaysian public sector. The duration for a trial of a new
innovation depends on the agreement between parties, namely the Malaysian public sector
agencies and vendors. The POC will be evaluated and tested by the organization with
current deployment in the ICT environments. The longer the duration of the POC, the more
support the vendors will have to give which allows the organization to be further exposed
to the new innovation. A new innovation such as cloud computing innovation that offers
the features of trialability or POC to experiment with before adoption will positively
influence the adoption rate in the Malaysian public sector. Thus, it is hypothesized that:
H4: Trialablity has an influence on the propensity to adopt cloud-based services in the
Malaysian public sector
2.5. IT Personnel Characteristics
IT personnel characteristics play an important role in IT innovation adoption in the public
sector. In some organizations, there is a Chief Information Officer (CIO), Manager or
Head of IT department/unit, and decision maker for IT projects. These individuals are
responsible for introducing, influencing, operationalizing, and guarding new IT innovation
in an organization. In addition, the IT personnel are the only individuals in the organization
who are involved from the beginning of the IT adoption until its completion aside from the
CEO or head of department. Thus, factors such as IT personnel innovation, attitude,
knowledge, and tenure are important individual dimensions that influence the success of
cloud computing in the Malaysian public sector.
The IT personnel can influence IT innovation adoption by transforming their knowledge
and innovativeness. Knowledgeable and innovative IT personnel are always focused on
getting the new technology in place. Due to the dominant role of the IT personnel,
particularly in public sectors, these aspects are essential in the adoption of a new
technology such as cloud computing. Thong and Yap (1995) found that individuals, who
have a willingness to innovate such as the CEO, CIO, and IT personnel, can positively
influence IT innovation adoption. In the public sector, the CIO and IT personnel are
usually the owners of the initial decision making in new IT innovation adoption. Moreover,
innovative CIOs or IT personnel are willing to take risks and always prefer new solutions
that have not been tried before (Gerow et al., 2012). Prior studies found that the CIO and
IT personnel’s innovativeness significantly and positively influences the adoption of IT
innovations (Gerow et al., 2012; Thong, 1999). The slow rate of IT innovation adoption
process in organizations has been attributed to the lack of expertise and knowledge in the
IT personnel (Looi, 2005; Premkumar and Roberts, 1999). Teo et al. (2007) in their study
on the adoption and diffusion of human resources information systems in Singapore found
that the essential long-term success and continuous growth of IT in an organization is
based on the availability of skilled and knowledgeable IT professionals. In addition, a
study by Smith (2008) on successful adoption of IT Projects in the Public Sector in US
shows that IT personnel expertise is a key determinant of public sector IT innovation
adoption. This leads to the following hypotheses:
H5: IT personnel innovativeness has a direct influence on the propensity to adopt cloud-
based services in the Malaysian public sector
H6: IT personnel knowledge has a direct influence on the propensity to adopt cloud-based
services in the Malaysian public sector
Sallehudin et al.

2.6. Propensity to adopt cloud-based services
Propensity to adopt cloud-based services is operationalized as an intention to use or adopt
cloud-based services by the Malaysian public sector. Intention to implement measures is
the dependent variable in this research model. It is defined as an organization’s intention to
implement or adopt cloud computing in the future. These are general measures using
forward-looking statements that capture the propensity of the organization. It will be used
to represent the usage of cloud computing. Psychology researches have indicated that the
intention to use is the best predictor of actual system usage (Ajzen, 1991; Davis, 1989;
Venkatesh and Davis, 1996, 2000; Venkatesh et al, 2012). It has been shown that the
propensity to adopt is directly related to actual use and in some studies, intention to adopt
or use and actual adoption have been used interchangeably.
3. Methodology
3.1. Participants
The study population comprises CIOs, Heads of Departments, IT Managers, and IT
personnel who are working in Malaysian public sectors. The selected sampling frame for
this study consists of 730 IT officers currently in service in various ministries,
departments, and agencies across the country. A purposive sampling technique was
employed. The reason for choosing this sampling frame is the relevance of its working
population to this study. An online survey questionnaire using Google Formswas
distributed to the sample of this study via the Malaysian public sector IT officers society’s
(Perjasa) Facebook group in May, 2014. During the data collection period, the number of
responses received for this study was only 85. Compared to the standard response rate of
60 percent as suggested by Hair et al. (2006), this study’s response rate is not high, but
falls in line or even better in some cases than previous studies. The respondents were
informed that their participation was voluntary and the information they provided was
confidential. The characteristics of the samples are shown in Table 1.

3.2. Survey Instrument and Analysis
Measures used in the study are presented in Table 2. All the items’ measures were obtained
from previous researches whose validity and reliability have been demonstrated. All
indicator variables are modeled as reflective because they are seen as functions of their
associated latent variables. The methodology to measure the research model for this
research is the structural equation modeling (SEM) of the data analysis. This approach has
many advantages over other methods such as the multiple regression. Using the SEM
approach, a partial least squares (PLS) method was selected. Partial least squares (PLS) are
a popular Structural Equation Modeling (SEM) technique used to conduct data analysis
(Goodhue, Lewis, and Thompson, 2006). SmartPLS version M3 2.0 (Ringle et al., 2005)
was chosen because the PLS is more suitable in handling relatively small sample sizes
(Hair et al., 2011) in contrast to the co-variance based (CVB SEM) techniques such as
AMOS and LISREL. In this study, the total usable sample of 85 respondents can be
viewed as a small sample size. Moreover, researchers in this field rely greatly on the PLS
for testing path models and theory confirmation (Goodhue et al., 2006).

4. Findings and Discussion
4.1. Validity and Reliability
Validity refers to how accurately the construct reflects what it intends to measure, and
reliability refers to the consistency of the results obtained. As suggested by Hair et al.
(2010), this study used factor loadings, composite reliability, and the average variance
extracted to assess convergent validity. As recommended by Hair et al. (2010), the
loadings for all items exceeded the value of 0.5. In addition, the composite reliability
values, as shown in Table 3, describe the degree to which the construct indicators indicate
the latent construct and they ranged from 0.876 to 0.974. These indicators exceeded the
recommended value of 0.7 (Hair et al., 2010). Moreover, the average variance extracted
(AVE), which reflects the overall amount of variance in the indicators accounted for by the
latent construct, ranged between 0.650 and 0.825. These indicators exceeded the
recommended value of 0.5 (Hair et al., 2010). This suggests that all measures in this study
sufficiently meet the validity. Discriminant validity was also established as the indicator

terms of how much it correlates with other constructs and how its particularly measured
variables represent only this single construct (Hair et al., 2010). Measures of discriminant
validity are supported when the square root of the average variance extracted for each
construct is the highest for its assigned construct (Fornell and Lacker, 1981). As shown in
Table 4, the correlations for each construct are less than the square root of the average
variance extracted by the indicators suggesting adequate discriminant validity. In total, the
measurement model demonstrated adequate convergent validity and discriminant validity.
4.3. Structural Model
Subsequently, this study assessed the structural model for the hypotheses testing. In this
test, the statistical significance was assessed by t-tests based on a bootstrap procedure with
1,000 bootstrapping samples. To evaluate the results, the explained variances, R2, and path
coefficients can be interpreted similar to those in the simple regression (Hair et al., 2010).
This study begins the interpretation with the hypothesized factors. As shown in Table 5,
three out of the six hypotheses were supported. Relative advantage (β = 0.338, ρ = 0.01),
Compatibility (β = 0.409, ρ = 0.01), and IT personnel knowledge (β = 0.227, ρ = 0.01) are
positively related to the propensity to adopt cloud-based services in the Malaysian public
sector. Thus, H1, H2, and H6 are supported while H3, H4, and H5 are not supported. All
the variables explain 75.4% of the variance in the dependent construct. This indicates that
in the proposed research, the conceptualization possesses adequate predictive power and is
useful in explaining future assimilation of cloud computing for the sampled Malaysian
public sector. Further discussion on the results is presented in the next section.

4.4. Discussion
In this study, Relative advantage was hypothesized to have a direct influence on the
propensity of IT personnel to implement cloud-based services in their department. This
study found that this hypothesis was supported. Therefore, it can be suggested that the
adoption of cloud-based services that is beneficial to the Malaysian public sector will
increase its assimilation. This result supports the studies of Alam et al. (2011), Chen
(2013), Law et al. (2013), and Premkumar and Roberts (1999) that have found relative
advantage to be a very significant factor in the decision to implement information
technology innovation.
Complexity was hypothesized to have a direct influence on the propensity of IT personnel
to implement cloud-based services in their department. This study found that this
hypothesis was not supported. This study also found that the path coefficient for
complexity was positive. It can be argued that while cloud computing features are
complicated and difficult to understand, the IT personnel found that this did not hinder the
adoption. In fact, they may feel that cloud computing features are easy to use in their

agencies’ IT system. This result supports the studies of Alam et al. (2011), Chen (2013),
Hung et al. (2010), and Ramdani et al. (2009) that have also found that complexity was not
a significant technological attribute in decisions to implement information technology
innovation.
Compatibility was hypothesized to have a direct influence on the propensity of IT
personnel to implement cloud-based services in their department. This study’s result found
that this hypothesis was supported. Therefore, it can be argued that the cloud computing
features that are compatible with all aspects of IT services in Malaysian public sector lead
to a higher level of intention in the IT personnel to implement it in their department. IT
personnel also found that cloud computing services are completely compatible with the
current IT system in their department, thus increasing cloud computing assimilation. This
result supports the studies of Alam et al. (2011), Chen (2013), Law et al. (2013), Luqman
and Abdullah (2011), and Premkumar and Roberts (1999) that have posited compatibility
as a significant factor in decisions to implement information technology innovation.
Trialability was hypothesized to have a direct influence on the propensity of IT personnel
to implement cloud-based services in their department. However, this study found that this
hypothesis was not supported. This study also found that the path coefficient for trialability
was negative. This finding contradicts with the works of Kassim et al. (2012), Law et al.
(2013), and Ramdani et al. (2009) that have consistently found trialability to be a very
important factor. It can be argued that while cloud computing must be experimented
without any constraints before its actual adoption in the Malaysian public sector, the IT
personnel found that it was not necessary. They may think that cloud computing adoption
with different layers and models of adoption would not support the proof of concept before
the actual adoption. Thus, they found that it is a barrier to adoption.
IT personnel innovativeness was hypothesized to have a direct influence on the propensity
of IT personnel to implement cloud-based services in their department. However, this
study found that this hypothesis was not supported. Therefore, it can be argued that the IT
personnel were not willing to bear the risks of implementing the cloud computing
technology in their department. The dark side of the cloud computing technology would be
the barrier for IT personnel from taking the risk of adoption in the Malaysian public sector.
This result contradicts with the studies of Gerow et al. (2012), Hung et al. (2010), and
Thong (1999) that have consistently found personnel innovativeness to be a significant
factor in decisions to implement information technology innovation.
IT personnel knowledge was hypothesized to have a direct influence on the propensity of
IT personnel to implement cloud-based services in their department. This study found that
this hypothesis was supported. It can be argued that the IT personnel’s experience and
knowledge about cloud computing leads to a higher level of intention to implement it in
their department. This result supports the studies of Looi, (2005), Premkumar and Roberts
(1999), and Teo et al. (2007), who have consistently found executive knowledge to be a
significant factor in decisions to implement information technology innovation.
4.5. Implications
This study has significant implications for both academic literatures both theoretically and
practically in IT innovation for the public sector. In the context of theoretical literature,
this study offers additional validation of the significance of IT adoption theory based on
Sallehudin et al.

Roger’s innovation attributes (Relative advantage, Compatibility, Complexity and
Trialability) that were used to measure different magnitudes of the approach toward
intention to adopt cloud-based services. There are many explanations that can describe the
possibly difference in results of this study from previous studies. It is implicit that Roger’s
Diffusion of Innovation theory applies to various research domains such as psychology,
sociology, marketing, and technology adoption. Therefore, the findings of the study based
on Roger’s innovation attributes might differ from one research field to another. In
addition, the combined theoretical perspectives can be used to better understand the
influence of various technological factors in cloud-based services adoption in the
Malaysian public sector.
Moreover, this study also found that both technology attributes, namely relative advantage
and compatibility were strong technological factors in IT personnel’s propensity to
implement cloud computing in their department. They viewed cloud-computing adoption
as advantageous in terms of enhancing service delivery and increasing the performance of
their department. They also regarded that cloud computing is compatible with their
department’s values and beliefs. In the dimension of complexity and trialability, this study
found that both Roger’s innovation attributes are not significant for IT personnel to
implement cloud computing in their department.
The findings also show the importance of the IT personnel’s characteristics in cloud
computing assimilation for the Malaysian public sector. A strategy to reduce the risk of
cloud computing adoption would lead to speed up the adoption in the Malaysian public
sector. The IT personnel are reluctant to adopt new IT innovation if the adoption is risky.
This finding supports the argument by Wyld (2009), who stated that the IT personnel in the
public sector were reluctant to jump into the cloud environment due to the fragile
environment of virtualization. Moreover, the IT personnel’s knowledge was found to be
significant in this study. This finding is supported by the reality in the Malaysian public
sector where awareness programs, technology update seminars, and ICT conferences
continuously highlight the cloud computing technology. Therefore, IT personnel in the
Malaysian public sector gain knowledge and experience regarding the cloud computing
technology once they join these programs.
Lastly, this study will also help policy makers in the Malaysian public sector to focus on
similar factors that will have a significant influence in the adoption or deployment of new
IT innovation, systems, or processes in the future. By now, the Malaysian public sector can
also start to ensure a smoother cloud-based services adoption plan by addressing the
characteristics of innovation and IT personnel in which their IT personnel will be most
likely concerned with.
6. Conclusion
The increase in cloud computing adoption by the governments in developed countries has
at least revealed what the governments understand about cloud computing – they are aware
of the operational and strategic roles and the impact of the cloud computing landscape in
today’s business. Despite this understanding, some governments are still waiting, and some
have searched for more convincing evidence that cloud computing assimilation will create
value before deciding on a major cloud computing investment and adoption. This study

focused on examining DOI and the effects of IT personnel characteristics on organizational
adoption of cloud computing technology in the Malaysian public sector.
The research was done under the theoretical framework that was developed based on a
previous study. The structural model assessment using t-test on SmartPLS shows that
relative advantage, compatibility, and IT personnel knowledge are significant factors of
intention to adopt cloud computing in the Malaysian public sector. The model explains
75.4% of the variance in IT personnel’s intention to implement cloud computing in the
Malaysian public sector. As the government is concerned about the e-Government
services, connected government, service delivery efficiency, shared-services, and public
service transformation, an understanding of the factors that influence the Malaysian public
sector’s adoption of the cloud computing is invaluable.
Although this study provides insightful results, there are some limitations that need to be
considered when examining the results. The survey was conducted in the Malaysian public
sector context via online questionnaires. Therefore, the findings cannot be generalized to a
global reality and even in Malaysia, the sample only considered those who have access to
the internet and joined the Perjasa’s Facebook group (based on the online questionnaire
posted on Facebook) and the results are not a representation of the whole population’s
perceptions and behaviors. In addition, the framework of this study needs further studies to
understand the factors that encourage the IT personnel to adopt an innovation in their
agency. Although the study was not able to statistically compare the results between cloud
computing adopters and non-adopters’ departments, it sheds some light on possible
differences between these groups. However, the proposed framework offered a few
contributions in understanding the propensity to adopt cloud-based services, since it
resulted in a high effect size in most of the supported path coefficients. In addition, some
factors in the framework, such as complexity, trialability, and IT personnel innovativeness,
did not work as expected. It is suggested that future studies focus more on understanding
why these factors, which are normally important in information technology adoption, were
not significant within the context of propensity to adopt cloud computing. It is also
suggested that future studies focus on other dimensions of factors such as organizational
and environmental factors based on Tornatzky and Fleischer's (1990) framework to better
explain the success factors of cloud computing adoption in the Malaysian public sector.
Studies that look at the adoption process by comparing the public and private sectors might
be interesting in shedding light on the differences between these groups toward the
adoption process of cloud computing technologies.

Adopting e-government services presents numerous challenges for governmental sectors in developing countries. These problems can fail some projects involving e-government. Therefore, a solution is required to address these problems. This paper presents a conceptual model and measurement to identify crucial factors that impact cloud computing technology in e-government to address the issues with e-government. According to the recent studies on technology adoption models, a theoretical model is proposed in this study. Extracting items from the literature and adapting them, creates the measurement scales for the proposed model’s structures. Through the use of face validity, pre-testing, and a pilot study, the authors confirm the scales’ content validity and reliability. The data used for this study were collected by the authors from 40 information technology IT professionals for the pilot study in the top 10 government departments in Libya who are responsible for many IT decisions in e-government. In this study, the authors first examine the reliability of the scale using Cronbach’s alpha and perform exploratory factor analysis to assess the scales’ validity. The data were analyzed using partial least squares structural equation modelling (PLS-SEM). The findings demonstrate that the scale measurements satisfy the standard requirements for the validity and reliability According to previous studies on cloud computing adoption from the IS perspectives, this paper theoretically provides a combination model for investigating the cloud-based implementation services to provide a more comprehensive model and the objective is to develop an empirical instrument for analyzing countries’ e-government adoption of cloud computing.
... Cost: According to [19] and [74], senior management's choice to accept or reject cloud computing is heavily dependent on the financial factor. According to [94,98] the cost factor takes into account the expenses related to staff training on how to use the technology as well as the initial setup and ongoing maintenance of cloud-based corporate systems. ...

Many governments in developing countries are finding it challenging to integrate cloud computing into their e-government systems because of the limited effective identification and evaluation of important factors. Cloud computing usage in government organizations is still restricted due to concerns over security, regulatory challenges, cultural resistance to new technologies, infrastructure limitations, and other factors (Abied et al. in Sustainability 14:15590, 2022). This research suggests a model that analyses the factors influencing the adoption of cloud computing in e-government systems within Jordanian government organizations by decision-makers. The survey was distributed online to a purposive sample consisting of 373 IT professionals and top-level managers in government organizations in Jordan. The study demonstrates that the technological factors which include complexity, compatibility, relative advantage, and security, the organisational factors which consist of top management support and cost, and the environmental factors which include industry competition and government rules and regulations, had a significant and positive impact on the adoption of cloud-based services in government systems. Furthermore, IT knowledge held by decision makers was recognized as a key factor in the adoption of cloud computing for e-government systems. This research is anticipated to provide significant insights for any organizations making investment decisions about the use of cloud-based services. This research considers the assessment of multiple aspects to encourage top management to analyse the consequences of implementing cloud services for e-government systems. This case study might not be applied broadly to all types of organizations in Jordan. Future research should employ large-scale samples to ensure the study's representativeness and could also broaden the scope by including samples from similar countries to validate the model or its implementation across different cultures, IT infrastructure and geographical settings. In addition, it is recommended that upcoming research consider using the level of experience and education as moderators.

Enterprise Architecture provides a holistic view that effectively integrates different domains in business, data, application, and information in organisations. Different notions of Enterprise Architecture (EA) models could be found in the literature which are primarily based on various factors and fragmented perspectives. However, current EA models are more focused on the post-adoption or implementation phase of EA. There is little attention paid on the adoption model of EA. It is also found that the organisational adoption of EA is still missing from technological, organisational, and environmental perspectives. Based on inferences from previous study, very few had attempted to find significant factors using the theoretical approach of Information Systems in the context of EA adoption. Therefore, this research is designed to investigate the factors that influence EA adoption at the organisational level and propose a conceptual model during adoption phase and early phase of the EA cycle. The research method used questionnaires administered to key participants from 23 Malaysian public sector organisations. The findings have shown significant factors influencing the intention to adopt EA. The strength of relationship in coercive pressure was the highest, followed by mimetic pressure. Furthermore, the complexity of EA did not have significant influence on the intention to adopt EA. Therefore, this study has addressed factors from the technological, organisational, and environmental perspectives that could influence the intention to adopt EA among Malaysian public sector organisations. The findings indicate that various pressures were the greatest influence in the adoption of EA.
... The intention to adopt cloud computing is positively related to performance expectancy, compatibility, security, and mobility in the technological aspect. These findings align with several previous studies [32], [33]. Malaysian public sector users believe that cloud computing improves their work performance. ...

As the need for digital content increases almost daily, preserving this content for university libraries, especially in the least developed and developing nations, becomes a challenge, resulting in the loss of this data. Even though most of these libraries are automated and adopt one digital preservation strategy or the other, library users need more assurance of continued access to these digital objects. Thus, there is a need for university libraries to adopt emerging technologies such as cloud computing for proper digital preservation. Owing to the insufficiency of knowledge on the relationship between technology and humans, taking account of human capabilities and how they work in harmony with technology like cloud computing called for a study of this nature. This study investigates the determinants of cloud computing adoption in university libraries, focusing on technological and human factors. A quantitative survey design technique was adopted, and purpose sampling was used. Data were gathered and analyzed from 398 staff from Information and Communication (ICT) directorates, e-library, and institutional digital repositories units of universities as decision-makers for IT adoption. Results show that all the variables under technological and human factors except for complexity have a positive relationship with the intention to adopt cloud computing. This study gives decision-makers like information scientists, librarians, and information technologists’ insights into how the two factors contribute to the successful adoption of cloud computing. It also contributes to the knowledge of technology adoption literature, adding more knowledge to the theory-building, especially in the context of university libraries.

The emergence and proliferation of cloud computing have caused a paradigm shift for organizations, moving them away from traditional servers towards data centers. Developed nations have extensively leveraged cloud computing to improve SMEs' operations, collaboration, and research, all while overcoming financial constraints. As such, the adoption of cloud-based services could prove to be highly significant for businesses of all sizes, including SMEs in developing countries. Despite the numerous benefits, SMEs in developing countries, particularly Pakistan, have hesitated to adopt cloud computing. In this study, a quantitative method will be employed, utilizing the Organizational Support Theory and the Technology-Organization-Environment theory, and moderator contribution variables relevant to the study, to investigate the factors influencing the intention to adopt a Cloud Computing Software-as-a-Service (CC-SaaS) model.

Cloud computing has emerged as a transformative technology in many industries, including academia. As large information repositories, university libraries stand to benefit significantly from the increasing use of cloud computing. University library services especially in developing countries have been limited to what can be provided within the physical premises, potentially leading to a less flexible and less accessible information service delivery model. This situation is driven by the existing technology divide and the myriad challenges associated with information technology (IT) adoption, such as political instability, deficiencies in IT infrastructure, regulatory policies, organisational constraints, and government initiatives or support. To enhance the efficient service delivery of university libraries through the adoption of innovative IT, a thorough study to consider organisational, environmental, technological, and human issues is needed because it can be used as guidelines to assist university libraries in leapfrogging their efforts as a motivation for adopting cloud computing technology for efficient service delivery. The present study examines the success factors contributing to the adoption of cloud computing in university libraries. In light of the abovementioned factors, a review of 25 papers was conducted using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) approach for study selection. The review’s findings demonstrate that various factors significantly influence cloud computing adoption in university libraries. Organisational factors, including top management support, training and education, organisational intention, and readiness, speed up the adoption process. Environmental factors, including competitive pressure, regulatory policies, government support, and service provider support, also impact the adoption of cloud computing. Technology-related factors, including relative advantage, compatibility, and complexity, must be considered for successful adoption. Furthermore, the extent to which cloud computing finds acceptance within university libraries is notably shaped by human factors, encompassing elements such as the attitudes and perceptions of staff towards IT change, the internal IT proficiency within the institution, and the prior technological experiences of the staff. Based on the findings, this study recommends formulating a comprehensive framework that considers all these constituent factors to facilitate the wider adoption of cloud computing in university library settings. Such a framework should focus on providing robust top-level management support, enhancing staff education and training, considering the influence of environmental factors, addressing pertinent technological challenges, and cultivating a pro-change mindset among library personnel

Generalized Audit Software (GAS) is critical for auditing a firm's financial statements. However, the usage of this software is widely limited to developed countries. The purpose of this study is to examine the usage of GAS among auditing firms in Jordan. Based on the technology organization environment framework (TOE), our study proposes organizational factors (technology cost benefits analysis (TCBA), technological compatibility (TC) (technological factors (TF), top management support (TMS), organizational readiness (OR), environmental factors (GAS complexity (GASC), and competitive pressure (CP)) to affect the GAS usage (GASU). Furthermore, auditor satisfaction was proposed as a moderating variable. Moreover, the data was collected from auditors using convenience sampling and analyzed using Smart PLS. The findings showed that TCBA, TC, TMS, OR, and GASC are critical predictors of GASU. Additionally, CP has an insignificant effect on GASU. Also, auditor satisfaction is not a moderating variable while big data moderated the effect of Technological factors on GAS. Lastly, more studies are needed in GASU in developing countries to understand the predictors of this technology among individuals. This means that decision-makers are advised to enhance the knowledge of auditors regarding the usage of GAS and to spread the knowledge regarding the benefits of GAS for auditors and auditing firms.

Cyberattacks negatively impact the performance of enterprises all around the globe. While organizations invest more in cybersecurity to avoid cyberattacks, studies on the factors affecting their overall cybersecurity adoption and awareness are sparse. In this paper, by integrating the diffusion of innovation theory (DOI), technology acceptance model (TAM), and technology-organization-environment (TOE) with the balanced scorecard approach, we propose a comprehensive set of factors that influence cybersecurity adoption and assess the effects of these factors on organizational performance. Data are collected through a survey of IT experts in small and medium-sized enterprises (SMEs) in the United Kingdom, with 147 valid responses. Structural equation modeling based on a statistical package for the social sciences (SPSS) was used to assess the model. The findings identify and confirm the importance of eight factors affecting SMEs' cybersecurity adoption. Moreover, cybersecurity technology adoption is found to positively impacts organizational performance. The proposed framework depicts variables influencing cybersecurity technology adoption and assesses their importance. The outcomes of this study provide a basis for future research and can be adopted by IT and cybersecurity managers to identify the most appropriate cybersecurity technologies that positively impact their company's performance.

The advent of Cloud Computing has brought tremendous growth to businesses. Enterprises, known for their cost savings, flexible and scalable features, are better managed today. Unfortunately, high dependency on service providers, data security issues, and high set-up costs are becoming major issues along with low adoption rates in developing countries. Despite the infrastructure deficit, there is a need for studies to focus on theories of adoption and use. Therefore, this study aims to systematically review empirical studies on the adoption and use of cloud computing in general to identify relevant factors determining organizational intention to use, actual use, and the impact of cloud computing services on performance. This study investigated the causal factors responsible for the adoption, use and performance of cloud computing through a systematic literature review. This study examined 150 related studies in various databases such as IEEE Xplore, Emerald, Springer link and Science Direct. Thirty-six (36) main factors were identified and the results showed that thirteen factors appeared most frequently: top management support, relative advantage, compatibility, security, complexity, technology readiness, firm size, competitive pressure, trial, cost savings, Perceived usefulness, perceived ease of use and personal innovativeness. Most of these factors are related to technology. This study serves as a foundation for future research and advancement of theory development in the adoption, use, and performance of cloud computing. It also provides inside information on user preferences and is crucial for service providers, business owners and government. Keywords: Cloud Computing, adoption, systematic literature review, determinants, utilization, performance.

The statistical tests used in the analysis of structural equation models with unobservable variables and measurement error are examined. A drawback of the commonly applied chi square test, in addition to the known problems related to sample size and power, is that it may indicate an increasing correspondence between the hypothesized model and the observed data as both the measurement properties and the relationship between constructs decline. Further, and contrary to common assertion, the risk of making a Type II error can be substantial even when the sample size is large. Moreover, the present testing methods are unable to assess a model's explanatory power. To overcome these problems, the authors develop and apply a testing system based on measures of shared variance within the structural model, measurement model, and overall model.

The adoption of e-business amongst small and medium sized enterprises in the state of Terengganu, Malaysia is still quite low. Hence, identifying the success factors that contribute to e-business adoption is crucial. This article examines the factors that determine the e-business adoption amongst small and medium enterprises and its causal effects using a theoretical model based on the Innovation Diffusion Theory. The research model consists of five exogenous latent constructs, namely relative advantage, compatibility, complexity, trialability and observability. Data relating to the constructs were collected from 337 small and medium sized enterprises located in the state of Terengganu, Malaysia and subjected to Structural Equation Modeling analysis. Confirmatory Factor Analysis (CFA) was performed to examine the reliability, construct validity, convergent validity and goodness of fit of individual construct and measurement models. The hypothesized structural model fits the data well. Results indicate that the significant factor that leads to the adoption of e-business is compatibility. Finally, implications and suggestions of these findings are discussed.

Despite the central role of information technology (IT) in contemporary firms, many Chief Information Officers (CIOs) still lack the influence over their executive teams that is enjoyed by other executives that report to the CEO. In this study, we propose power and political skill are related to the CIO's influence over the executive team's commitment to strategic and technical IT initiatives. We use Multivariate GLM to empirically examine these relationships using data collected from 127 CIOs. The results suggest the CIO's formal position in the firm, the CIO's business and technical knowledge, and the important connections the CIO has established relate to the CIO's influence over the executive team's commitment to IT initiatives. We also found political skill moderates the relationship between the CIO's power and influence over the executive team's commitment to IT initiatives. We discuss the implications of these results for research and practice. © (2012) by the AIS/ICIS Administrative Office All rights reserved.
