Measuring e-Commerce Success: Applying the
DeLone & McLean Information Systems
Success Model
William H. DeLone and Ephraim R. McLean
ABSTRACT: Information technology and the Internet have had a dramatic effect on busi-
ness operations. Companies are making large investments in e-commerce applications
but are hard pressed to evaluate the success of their e-commerce systems. The DeLone &
McLean Information Systems Success Model can be adapted to the measurement chal-
lenges of the new e-commerce world. The six dimensions of the updated model are a
parsimonious framework for organizing the e-commerce success metrics identified in the
literature. Two case examples demonstrate how the model can be used to guide the iden-
tification and specification of e-commerce success metrics.
KEY WORDS AND PHRASES: e-commerce, evaluation of information systems, informa-
tion systems success, use of information systems, user satisfaction, value of information
technology.
The Internet has dramatically affected the conduct of business. Markets, in-
dustries, and businesses are being transformed. The new economy demands
the exploitation of new models and paradigms. Information technology (IT)
now drives businesses and markets. In the new economy, the Internet has
become a powerful and ubiquitous communication mechanism to facilitate
the consummation and processing of business transactions. This has led to
substantial changes in traditional industries and companies. Firms are attempt-
ing to understand and measure the impact of IT so that they can make intelli-
gent decisions regarding crucial IT investments.
All this notwithstanding, basic business principles still hold. The laws of
economics have not been rewritten. The long-term success or failure of com-
panies is determined by their ability to generate positive net revenues. Simi-
larly, there has been no change in the fundamental role of IT in facilitating
business transactions and communicating relevant information to decision-
makers. However, the decision makers now include customers, both internal
and external. Time compression and the magnitude of change may be dra-
matic, but IT still has the same goals and objectives.
This paper proposes that even though new business models are emerging,
the fundamental role of IT has not changed, and thus the methodology for
measuring the success of information systems (IS) should not change. Although
there are many new technological developments, the dependent variable—IS
success—and its underlying dimensionalities are still the same. The DeLone
& McLean IS Success Model is an existing success-measurement framework
that has found wide application since its publication in 1992 [7]. With the
addition of new metrics, an updated version of the model can be applied to e-
commerce success measurement [8, 9].
For the purposes of this paper, e-commerce is defined as the use of the
Internet to facilitate, execute, and process business transactions. Business

transactions involve a buyer and seller and the exchange of goods or ser-
vices for money.
Updated DeLone & McLean Success Model
The original DeLone & McLean Success Model provided a comprehensive
framework for measuring the performance of information systems [7]. The
new and updated model is based on the empirical and theoretical contribu-
tions of researchers who have tested or discussed the original model [8, 9].
The updated model, presented in Figure 1, consists of six interrelated dimen-
sions of information systems success:
• System quality
• Information quality
• Service quality
• Use
• User satisfaction
• Net benefits
The primary improvements to the original model include (a) the addition
of service quality to reflect the importance of service and support in success-
ful IS systems, and (b) the collapsing of individual impacts and organizational
impacts into a more parsimonious net benefits construct.
Service Quality
In the original formulation of the DeLone & McLean model [7], the dual di-
mensions of system and information quality seemed sufficient to capture the
essential characteristics of information systems being delivered to users. In
the intervening decade, however, it became apparent that a third dimension
was needed, service quality [8, 9]. As Pitt, Watson, and Kavan observed, “Com-
monly used measures of IS effectiveness focus on the products rather than the
services of the IS function. Thus, there is a danger that IS researchers will
mismeasure IS effectiveness if they do not include in their assessment pack-
age a measure of IS service quality” [32, p. 173].
This need has become even more apparent with the advent of e-commerce
and the demand of customers for support from their Web providers. Thus,
service quality is added to Figure 1.
Net Benefits
The new net benefits construct immediately raises three issues that must be
addressed: What qualifies as a “benefit”? for whom? and at what level of
analysis? The original formulation of the DeLone & McLean model used the
term “impact.” Seddon used “consequences” and “net benefits” in his charac-
terization of outcomes [38]. We have come to prefer “net benefits” because the

original term, “impacts,” may be positive or negative, thus possibly leading
to confusion as to whether the results are good or bad. In addition, the inclu-
sion of “net” in “net benefits” is important, because no outcome is wholly
positive and without any negative consequences. Thus, “net benefits” is prob-
ably the most accurate descriptor of the final success variable.
The second issue of concern is benefits for whom—the designer, the spon-
sor, the user, or others? Different actors or players may have different views of
what constitutes a benefit. Thus, it is impossible to define net benefits without
first defining the context or frame of reference. The fact that the DeLone &
McLean model does not define the context is a matter of detail, not of over-
sight. The focus of any proposed study must be defined. The model may be
useful to both Microsoft and the user community, but each may have a very
different definition of what constitutes net benefits—and thus IS success—
from its own perspective.
Finally, the level of analysis must be addressed. Are the benefits to be
measured from the individual’s perspective, the employer’s, or that of the
industry or of the nation? The challenge for the researcher is to clearly and
carefully define the stakeholders and the context in which net benefits are to
be measured.
The DeLone & McLean Success Model for
e-Commerce Measurement
Since its publication in 1992, nearly 300 articles in refereed journals have re-
ferred to, and made use of, the DeLone & McLean IS Success Model as the
basis for measuring the dependent variable in IS research [7]. The model is
based on Shannon and Weaver’s classic communication theory, as adapted by
Mason, to measure IS impacts [23, 40]. As a powerful communications and

commerce medium, the Internet is a communication and IS phenomenon that
lends itself to a measurement framework (i.e., the DeLone & McLean model)
built on communication theory. In the e-commerce context, the primary sys-
tem users are customers or suppliers rather than internal users. Customers
and suppliers will use the system to make buying or selling decisions and
execute business transactions. These electronic decisions and transactions may
affect individual users, organizations, industries, and even national economies.
Molla and Licker first proposed that the original DeLone and McLean model
could be extended to measure e-commerce success [25]. This paper is based
on the updated DeLone and McLean IS Success Model as revised in 2002 and
extended in 2003 [8, 9]. Molla and Licker used the original DeLone and McLean
model published in 1992 as a basis of their proposal [7, 25]. This paper adds
the new construct of service quality and updates the important net benefits
construct (i.e., individual and organizational impact constructs in the original
model), and it provides an extensive list of success metrics based on a com-
prehensive review of e-commerce articles in the IS and marketing literature. It
concludes with two case examples that demonstrate the utility of the pro-
posed e-commerce success framework. Molla and Licker did not attempt to
demonstrate the application of the model.
The six success dimensions of the DeLone & McLean IS Success Model can
be applied to the e-commerce environment as follows:
1. System quality, in the Internet environment, measures the desired
characteristics of an e-commerce system. Usability, availability,
reliability, adaptability, and response time (e.g., download time) are
examples of qualities that are valued by users of an e-commerce
system.
2. Information quality captures the e-commerce content issue. Web
content should be personalized, complete, relevant, easy to under-
stand, and secure if prospective buyers or suppliers are to initiate
transactions via the Internet and return to a site on a regular basis.
3. Service quality, the overall support delivered by the service provider,
applies regardless of whether the support is delivered by the IS
department or a new organizational unit or is outsourced to an
Internet service provider. This dimension is more important in an e-
commerce environment than ever before, because the users are now
customers rather than employees, and therefore, poor user support
will translate into lost customers and lost sales.
4. Usage measures everything from a visit to a Web site and navigation
within the site to information retrieval and execution of a transaction.
5. User satisfaction is an important means of measuring customers’
opinions of an e-commerce system and should cover the entire
customer experience cycle from information retrieval through
purchase, payment, receipt, and service.
6. Net benefits are the most important success measures, because they
capture the balance of the positive and negative impacts of
e-commerce on customers, suppliers, employees, organizations,
markets, industries, economies, and even society as a whole. Have
Internet purchases saved individual consumers time and money?
Downloaded by [Georgia State University] at 13:12 28 July 2015
INTERNATIONAL JOURNAL OF ELECTRONIC COMMERCE 35
Have the benefits, such as larger markets, supply-chain efficiencies,
and customer responsiveness, yielded positive net benefits for an
organization? Have country investments in e-commerce infrastruc-
ture yielded a net positive growth in GNP? Have societal invest-
ments in e-commerce infrastructure and education reduced poverty?
Net benefits measures are determined by the context and objectives of the
specific e-commerce investment. There will be a variety of e-commerce net
benefits measures, but many will be the same ones that have been developed
and tested for information systems investments in general.
Net benefits success measures are clearly important, but they cannot be
analyzed and understood without system, information, and service-quality
measurements. For example, in the e-commerce environment, the impact of a
Web site design on customer purchases cannot be fully understood without
an evaluation of the usability of the Web site and the relevance for purchasing
decisions of the information provided to the prospective purchaser.
E-Commerce Metrics: Old and New
A review of articles on e-commerce and electronic data interchange (EDI) in
recent academic and trade journals (1996–2002) yielded many suggested mea-
sures of e-commerce success. IS and marketing journals were included in the
search for e-commerce success metrics. Most of the articles were conceptual
in nature, but some were empirical and, therefore, attempted to operationalize
e-commerce success metrics. Some of the proposed measures are IS measure-
ment staples, whereas others have been newly developed for the e-commerce
environment. Most important, all of the proposed measures can be classified
under the six dimensions of the DeLone & McLean model.
The collections of e-commerce measures identified in the journals are dis-
cussed below under the relevant DeLone & McLean success dimensions. These
e-commerce success measures are listed in Tables 1 through 7. The tables differ-
entiate traditional management information systems (MIS) success measures
that have been applied to e-commerce and new measures that have surfaced
recently in the e-business environment. The e-commerce metrics identified in
the tables are meant to be illustrative and not necessarily comprehensive.
System Quality
The system quality metrics for e-commerce shown in Table 1 are primarily the
metrics that have been used in IS research for the last two decades. The key
measures of system quality are still usefulness, usability, responsiveness, reli-
ability, and flexibility. Some of the functionality item measures, such as
versionablity, are likely to differ in the e-commerce environment. What is dif-
ferent is the relative importance of the system-quality measures. When the us-
ers are customers as opposed to employees, their use is typically volitional, and
this means that poor usability, usefulness, or responsiveness can discourage
customer usage of an e-commerce system. Expected benefits are unlikely to be

realized when system quality is unsatisfactory. In addition, system security be-
comes a more significant system-quality issue, because e-commerce is typically
conducted over the Internet rather than a private, proprietary network.
Information Quality
Research articles on e-commerce have not devoted much attention to infor-
mation-quality or content-quality success measures (see Table 2). Many of the
traditional information-quality measures apply, especially relevance. When
customers are the users, and customer-purchase decisions are the objective,
new, dynamic personalization measures are important because of the mass
customization developments occurring in sales and marketing.
Service Quality
Liu and Arnett identified service quality as an important measure of Web site
success [21]. In their empirical study, service quality was measured as quick

responsiveness, assurance, empathy, and following-up service. Service quality
can also be measured by the effectiveness of on-line support capabilities, such
as answers to frequently asked questions, customized site intelligence, and
order tracking [25]. None of the other e-commerce articles reviewed for this
paper addressed service quality (i.e., user support). There is no debating the
importance of supporting customers as they attempt to execute transactions
via e-commerce systems, whether the support is offered through help desks,
hotlines, service centers, or the like. It is necessary to look to the service-quality
research stream for success measures that make sense in the e-commerce envi-
ronment—measures such as responsiveness and technical competence.
User Satisfaction
The literature review did not reveal any e-commerce-specific instruments for
measuring user satisfaction. Molla and Licker emphasize the importance of
“customer e-commerce satisfaction” and define it as “the reaction or feeling
of a customer in relation to his/her experience with all aspects of an e-com-
merce system” [25, p. 7]. Reichheld and Schefter’s “e-loyalty” represents a
good surrogate measure of customer satisfaction in the e-commerce environ-
ment [36]. Mehta and Sivadas proposed that customer attitudes are impor-
tant measures of e-commerce success [24]. It is recommended here that
researchers adopt and adapt user information satisfaction and end-user sup-
port satisfaction instruments as appropriate for specific e-commerce research.
Some items will need to be reworded, and new items will have to be added to
the traditional measurement instruments.

System Use
As with traditional information systems [18], customer or supplier use is an
important measure of success for e-commerce systems, especially because
customer use is more often voluntary. The nature and amount of the usage are
both important indicators of success. The usage metrics in Table 3 were found
almost exclusively in the trade literature.
Net Benefits
Measures of net benefits success address the ultimate impact of the e-com-
merce system and therefore represent the most important category of success
measurement. An e-commerce or e-business system can benefit a single user
(usually a customer), a group of users, an organization, or an entire industry.
Hence, the net benefits success measures found in the literature are organized
by level (individual, group, organization, and industry e-commerce measures)
in Tables 4 through 7. Two factors accounted for the many new e-commerce
success measures identified in this section: (a) the new context—e-commerce,
and (b) the new research domain—marketing research literature in addition
to IS literature.
How do individual users benefit from the use of e-commerce systems? The
individual benefit measures identified in the MIS and marketing literature
can be found in Table 4.
The Internet and e-commerce systems enable people to work together to
achieve specific objectives. How do groups of users benefit from the use of e-
commerce systems? The group benefit measures identified in the MIS and
marketing literature are shown in Table 5.

tified in the MIS and marketing literature can be found in Table 6. Not sur-
prisingly, traditional organizational success measures, such as cost efficien-
cies, increased sales, profits, and return on investment, are suggested as key
e-commerce success measures. Some measures not typically found in MIS re-
search are proposed as well, such as global reach and click-to-buy ratio.
The Internet has facilitated interorganizational communications that have
resulted in industry-level efficiencies. How do industries benefit from the use
of e-commerce systems? The industry benefit measures identified in the MIS
and marketing literature can be found in Table 7.
One article located in the literature search proposed economy-level mea-
sures of e-commerce success. Colecchia proposed three dimensions of success
at the country level: readiness for e-commerce as measured by access and
technology infrastructure; intensity as measured by e-commerce transaction
volume; and impact as measured by economic-efficiency gains, employment
gains, and new products and services [5].

the e-commerce environment, the system users are customers and suppliers,

and the purpose of the system is primarily the execution of business transac-
tions. Thus, the e-commerce context does not require a new set of success
metrics. The updated DeLone & McLean model can serve as an appropriate
framework for organizing e-commerce success metrics.
Applying e-Commerce Success Measures:
Two Case Examples
The utility of the updated DeLone & McLean IS Success Model and related e-
commerce metrics can be demonstrated with two case examples. One involves
a large, high-profile “bricks-and-clicks” business, and the other a small, tradi-
tional, regional retailer. The proposed e-commerce metrics are meant to be
demonstrative rather than exhaustive. In other words, the two examples show
how the DeLone & McLean model can be used to guide both practical and
empirical success studies. Although the examples are compelling logically,
the next step is to test the metrics empirically.
Case 1: Barnes & Noble
The entry of Barnes & Noble into on-line book sales in 1997 is well documented
in two Harvard Business School cases entitled “Leadership Online: Barnes &
Noble vs. Amazon.com” [19]. Amazon.com’s growth in sales and market value
demonstrated the value of the on-line model. Customers could order from
their homes. More titles were available than at brick-and-mortar bookstores,
and at lower prices. Detailed customer information enabled on-line bookstores
to personalize their customers’ electronic purchasing experience. Barnes &
Noble decided to compete opposite Amazon.com in cyberspace. The purpose
here is not to discuss this well-known case in detail but to consider the mea-
sures by which Barnes & Noble might measure the success of its e-commerce
business. A proposed e-commerce success measurement model is displayed in
Figure 2 using the updated DeLone and McLean framework [8, 9].
The ultimate measures of success for Barnes & Noble’s on-line book sales
business are incremental sales revenue and investor reactions to the company’s
“success” as reflected in its market valuation. To understand these net benefit
results, the e-commerce researcher must also measure the quality of the user’s
experience and the customer’s usage of, and satisfaction with, the system.
The Barnes & Noble Web site must be easy to use and available whenever the
customer wishes to access it. The information displayed must be relevant to
the customer’s interests and must be complete. A quick e-mail response to
purchase transactions is an issue of on-line service quality. If the customer’s
question cannot be resolved by e-mail, then a call center should be available.
Customers’ usage can be measured by the frequency of their site visits, and
their satisfaction can be measured by repeat purchases. All these measures, as
displayed in Figure 2, represent a comprehensive (but again, not exhaustive)
success measurement model for Barnes & Noble on-line, based on the up-
dated DeLone & McLean model.

Case 2: ME Electronics
ME Electronics (the company name is changed for confidentiality) is a quality
consumer electronics retail chain targeting wealthy customers by offering high-
end audio and video brands through nine retail stores in a large metropolitan
area. ME Electronics has maintained a Web site for the past four years. The
Web site supports a broad-based communications strategy and serves as a
one-way communication channel to the customer, used to disseminate com-
pany information, such as new product introductions. At present, customers
cannot place orders through ME’s Web site. ME faces a competitive challenge
from large-scale electronics retailers with fully functional e-commerce sites.
ME’s e-business strategy for the near future is based on electronic customer-
relationship management (ECRM). The strategy involves an interactive Web
site and a comprehensive customer database that tracks all customer interac-
tions. The value proposition involves service excellence through greater con-
venience, lower costs, and personalized customer service.
The purpose here is not to discuss the wisdom of this strategy but to dem-
onstrate the utility of the updated DeLone & McLean model in an entirely
different e-commerce context. How should ME Electronics measure the suc-
cess of its new e-business efforts? An e-business success model for the firm is
displayed in Figure 3.
The strategic objective of ME Electronics’ new e-business strategy is CRM.
The net benefit of this new strategy should be increased sales per customer.
This benefit will be realized only if customers are satisfied with their Web site
experience. They should be encouraged to periodically complete e-mail-based
customer-satisfaction surveys that measure system quality (download speed
and ease of use), relevance of the information found on the site, ME’s respon-

siveness to customer e-mail inquiries, and overall satisfaction with the on-line
experience. ME should also collect data on the number of electronic interac-
tions with each customer and correlate interactions with sales activity. All these
measures, as displayed in Figure 3, represent a comprehensive success-mea-
surement model for ME Electronics’ new e-business strategy.
These two examples demonstrate the flexibility and relevance of the up-
dated DeLone & McLean model as a framework for measuring e-commerce
success.
Conclusions and Recommendations
This paper adapts the well-established DeLone & McLean IS Success Model
to the metrical challenges of the new e-commerce world [7, 8, 9]. Drawing
from the IS and marketing literature published over recent years, the six di-
mensions of the updated DeLone & McLean model comprise a parsimonious
framework for organizing the various e-commerce success metrics identified
in the literature. This exercise leads to the following recommendations.
Researchers and practitioners should not let themselves be carried away
by the hype of the new economy and led to believe that this new and rapidly
changing environment requires entirely new measures of IS success. One
should look first at the cumulative tradition, and determine which existing
and validated success measures can be used in the e-commerce environment.
As much as possible, tried and true measures should be enhanced and ex-
panded with modifications or, where necessary, new measures should be con-
sidered. Selection of e-commerce success dimensions and measures should be
contingent on the objectives and the context of the empirical investigation,

but tested and proven measures should be used whenever possible. Com-
pletely new and untested metrics should be adopted only as a last resort.
The multidimensional and interdependent nature of e-commerce success,
as reflected in the DeLone & McLean IS Success Model, requires careful atten-
tion to the definition and measurement of every aspect of this dependent vari-
able. It is important to measure the possible interactions among the success
dimensions in order to isolate the effects of independent variables on one or
more of them. Cause can too easily be confused with effect. Viewing the DeLone
& McLean IS Success Model from both a process perspective and a variance
perspective, as suggested by Seddon [38], can be useful in identifying and
understanding these interactions.
Furthermore, despite the multidimensional and contingent nature of e-com-
merce success, an attempt should be made to significantly reduce the number
of different measures used to measure success, so that research results can be
compared and findings validated.
Finally, e-commerce studies should include net benefits measures and not
be content to collect only surrogate measures, such as Web site hits (i.e., use).
Such benefits can be measured on at least four levels: individual, group, orga-
nizational, and industry. Tables 4 through 7 give examples of measures for
each level. Taken together, the metrics presented in this paper, and especially
in the two case examples, show that a blending of well-established and new
measures is needed. These measures become most useful, however, when fit-
ted into an overall structure or framework—a framework like the one pro-
vided by the DeLone & McLean Information Systems Success Model.
