1.0 INTRODUCTION
Availability of information technology will enable
accessibility of more efficient communication and control,
which is essential to a competitive global logistics
capability. The impetus for strategic use of Management
Information System (MIS) has been highlighted as the
world transits into a global village. There is growing
research interest in the use of MIS as a strategic weapon by
organisations. Globalisation and competitive pressures
have heightened the impetus for strategic use of MIS. More
specifically, Warehouse Management System (WMS)
designed to introduce improvement into every aspect of a
company’s warehouse operations offers an organized
approach to manage efficiency. Bar code data collection
solutions for warehouse management system provides
powerful and flexible automatic identification system that
connects the shop floor to the enterprise software.
By integrating advanced radio frequency and bar coding
technologies with core warehousing functionality, WMS
provides comprehensive fulfilment centre and warehouse
management, including receiving, stocking, picking and
related warehouse tasks. The best-of-breed solution
leverages state-of-the-art technology to deliver all of the
functionality needed to maximise operational efficiency and
increase throughput, thus meet the primary focus of
warehouse in accuracy and timely fulfilment of customer
orders.
2.0 LITERATURE REVIEW
Literature review reveals that organisations must be capable
of fast, radical changes and those that aspire to be best must
lead in changes. According to Oxley (1990) efficient
management information system means (a) Quickly and fast
response to change, (b) Accurately, (c) Minimum clerical
effort, (d) Up-to-date, and (e) Available where and when
needed. Orlikowski and Robey (1991) study systems
development and the organisational consequences of using
IT based on Gidden’s theory of structuration. Powell and
Dent-Micallef (1997) investigate linkages between IT and
firm performance.
Benefits realised from information technology
communication are information availability, labour pricing
and material tracking (Peters, 1994). Boyson, et al (1999, p.
14) reported benefits from a more open information flow as
(a) Improve planning, (b) Develop active operations, (c)
Smooth product flows, (d) Time cost, and (e) Improve
service. Yaoa and Carlsonb (1999) concluded that better
inventory control reflected in increased inventory accuracy
and timeliness of real-time data permits the distribution
activities to be performed with confidence and improved
profitability. Barut, Faisst and Kanet (2002) measure the
magnitude and the effectiveness of logistics information to
firms in both directions of the supply chain. Ahmad and
Schroeder (2001) analyses on the benefits gained from
electronic data interchange (EDI) usage. Helo and Szekely
(2005) review software applications for their functionalities
and resulted benefits in relation to supply chain
management (SCM). Murphy and Simon (2002)
incorporate intangibles e.g. improved customer service into
traditional cost benefit analysis in an ERP project. Kuo and
Smits (2003) identify factors that improve the performance
of integrated supply chains performance, while Evans,
Towill and Naim (1995) concluded that SCM could be
enhanced through Business Process Re-engineering (BPR)
characteristic of not afraid to be radical with respect to
internal integration and continually search for step change
improvement ideas. Attaran (2004) examines relationships
between information technology (IT) and BPR, arguing that
those aspiring to do BPR must begin to apply the
capabilities of IT to reap benefits for successes.
3.0 METHODOLOGY
Single-case study approach is applied in this study to
understand the system being examined in the period of time
available. The primary aim of this paper is to analyse in-
depth to provide description and interpretation of business
performance improvement in multi-perspectives that is
induced by implementation of warehouse management
system. Evidence of data is collected from multiple sources
including documentation, archival records and direct
observation.
4.0 CASE DESCRIPTION
The distribution centre of study’s holding company, Sharp
Corporation, has been involving in TV manufacturing for
more than fifty years and pioneer in LCD technology for
over thirty years. The key products of the company are
LCD TV and solar cells. The primary business operation of
the company in this study, a business unit level distribution
centre, is procurement and distribution of service parts for
both business and consumer electrical appliances. The
distribution centre has been in business in operation of
distributing electronics parts worldwide since 1995. This
business focuses on product quality and customer
satisfaction. The business unit is among its counterparts.
Value-added services of the distribution centre is to provide
‘pick and pack’, and individual packaging. Quality
management improvement programme is implemented to
aim for zero defect through 5S, QCC activities and
ISO9001: 2000 Quality Management System. ABC
Management is applied in Inventory Management.
The distribution of electronics service parts revolves around
a certain number of physical (materials) and informational
(communication) flows that enable actor to source:
The right parts: service parts having increasingly
become an integral part of electrical modules
In the right place: physical service parts of from
manufacturers to dealers usually transit via
distribution centre
At the right time: a distinction is generally made
between urgent deliveries and replenishment
operations
Logistics Management System, more fondly known as
Warehouse Management System (WMS) is a MIS
investment in a warehouse. SAP is the abbreviation of
System for Application and Products. The distribution
centre’s Warehouse Management System (WMS)
developed by a local software house. For information flow,
customers place sales orders via the linked SAP system
which in turn are passed on as outbound delivery actions.
This delivery information is then processed by WMS and
made available on each user’s RF scanner. Orders are
picked, boxed and printed despatch labels and routes for
shipping. Completed delivery confirmation documents are
then transmitted to the SAP server and from SAP to notify
the customers.
The distribution centre has replaced its older, host-based IT
structure with a client / server architecture with
implementation of SAP R/3 System, and development of
new stand-alone warehouse management system in a
consolidated warehouse. Transactions can either be
executed at local PC or via a portable RF terminal, thus
making critical information immediately available. The
workers need wireless terminals with real-time radio
communication to the Warehouse Management System. It
requires radio frequency (RF) network and a
communications server on the network. Operations
functions can be performed from either a windows-based
workstation, hand-held RF mobile computers or any
combination of the two simultaneously.
4.1 Configurations
SAP and WMS are linked by lease line from the distribution
centre office in Shah Alam and warehouse in Port Klang.
The server that interfaces with WMS server is the
Application Server known as of SAP R/3 system furnished
with modules Sales and Distribution (SD) and Financial
Management (FI). The WMS server hardware is HP server
with Server / Client OS Windows NT server. The WMS is
VB program with an MS SQL Database 2000 on a
Windows NT operation system platforms using client/server
network architecture that provides a standard suite of
products. The Minimum hardware requirement is PC with
LAN card (NIC 10/100 mbps). They are over 70 end-
users are linked to the WMS application. The mobile
device is connected to the network using radio frequency
(RF) standard of 802.11b (11 mbs) and will communicate
using TCP/IP. The protocol used is TCP/IP. Through the
adoption of these standards, the application has been made
device independent, permitting the organisation use a wide
variety of mobile devices. The Bar code printer
manufacture is Sato, and the data input devices
manufacturers are Denso (Batch Handy Terminal, BHT)
and Fujitsu (Radio Frequency, RF terminals).
4.2 Host Interfaces
Interface Features:
Interfaces easily with host-based systems
Real time and /or batch host integration
Inventory interfaces
Order interfaces
Delivery data will update stock and the order data files.
Receiving order receipts will update stock, and the order
data files. The dispatch records will be used to update
picking lists with the confirmed quantities. If there is a
discrepancy in the stock, the ‘amend dispatch quantities’
option can be used to reduce the picking list quantity.
Hence, these interface data enable the distribution centre to
manage effectively the coordination of information
including demand, capacity, inventory and scheduling,
4.3 Inbound logistics
The inbound processes use Batch Handy Terminal (BHT).
Inbound System Features are:
Receipts immediately visible and tracked from arrival
Receipts referenced by PO
Directed Put Away
Location verification to ensure correct placement
Pre-receiving via manual entry or electronic data
interchange (EDI)
On-line validation against PO information
Receiving Discrepancies Report
Cycle counting for partial inventory checking
Verification of physical counts and storage accuracy
Cycle count post or reissue
Adjusts warehouse and SAP inventories
When checking in items, WMS notifies warehouse staff if a
received good is needed to fulfil a customer backorder. In
this event, instead of moving the item to storage location, it
is prepared for shipping directly to the awaiting customer.
Receipt from supplier occurs when the goods deliver to the
warehouse, and the bar codes should be attached to the
items that will then be scanned into the warehouse. The
incoming instruction number and the quantity will be
entered into the scanner, and the bar code will be scanned.
Inbound part is matched against expected receipts according
to receiving tolerances (date, quantity, and ship-to-location).
WMS enables real-time tracking of receiving, storage and
immediate access to information on combined statistics of
weight and lines for a specified customer.
4.4 Outbound Logistics
The outbound processes use Radio Frequency (RF)
terminal. Outbound System Features are:
Orders accepted from any host systems
System directed pick and real-time verification
Packing Lists
Track and process customer orders
Supports prioritising orders
Weight capture at picking
Pick to Pack
Picks confirmed through shipping process
Interfaces to SAP to confirm the shipment orders
Customer orders are automatically allocated, and delivery
order is also automated by linking the picking ticket to
terminals. The standard printed picking list will be used by
the warehouse for the dispatching of stock. The number will
be entered into the scanner where bar code for each item on
the picking list will be scanned. A quantity will be entered
via further bar codes scanned.
4.5 Inventory Management
Inventory Management Features are (a) real-time storage
usage, and (b) security through user passwords and access
authority levels. Stock take will be performed for the entire
warehouse. The scanner will allow entry of a location
reference via the scanner. Bar codes would then be scanned
and either a quantity entered or further bar codes scanned.
4.6 Management Reporting
The Reporting Features are:
View storage utilisation in real-time
Ad hoc query function
Export to text, Excel and CSV text files
Detailed Item (SKU) Report
Detailed Locations Report
Receiving order status
Shipping order status
Distribution systems in globalised competitive environment
cannot tolerate delays in data capture and reporting of
inventory detail such as their locations and movement. A
network-based decision support system (DSS) via Business
Objects (BO) was
developed to provide a systematic and consistent way to
analyse logistics management. Therefore, availability of
these management reports and analysis enables quick and
better decision-making and prioritisation.
5.0 CASE ANALYSES AND DISCUSSION
Radio Frequency WMS that utilises bar code technology
have many advantages. The following is a list of the most
common benefits that directly result from implementing a
WMS.
Leveraging RF-based bar coding technologies and seamless
integrating with order entry, WMS tightly orchestrates these
activities. WMS provided better workload control for view
of completed and upcoming activities. While checking in
received good, it is prepared for shipping directly to the
awaiting customer if the item is needed to fulfil a customer
backorder, while eliminating the introduction of
transcription errors. It reduces labour costs and increases
productivity. In average incoming cycle has been reduced
from average 3.71 days to 1.02 days. It was observed that
the lead-time has been reduced by 73% in the period.
The final phase of receipt and put-away processing is the
automated update of purchase orders and inventory
information into SAP that eliminates manual intervention
and errors, while providing accurate and up-to-date
inventory control. It reduces safety stock, stock shrinkage
and spoilage. Administrative is improved because the work
of printing and distributing picking lists or labels is
contained, as is the task of keying in picking confirmations
and picking amendments. WMS offers a streamlined
shipping solution that produces shipping labels, picking
slips, carton content labels and advanced shipping notices
eliminating errors in transcription from customer order.
The Outbound lead-time for air freight (AF) for subsidiaries
has been reduced from 9.94 days to 4.29 days, which is a
reduction of 57%. The WMS provides a fast order handling
process to keep distribution costs to a minimum.
WMS reducing human errors inherent in manual and paper
based systems. Inventory Accuracy improved from 98.34%
to 99.52%. This occurs by allow access all departments
within company to the same set of accurate inventory data.
The WMS offered physical scanning of items, locations and
boxes so that the contents of any order or storage location
can be viewed in real-time. Floor workers connect to the
WMS data using wireless RF terminals, which customer
services users and business analysts access through a GUI
interface to check delivery status. Transparent and accurate
inventory data allows employees in distribution,
procurement and warehouse departments to work from the
same information, thereby ensuring greater customer
satisfaction, a more efficient order handling process, and
keeping warehouse management costs to a minimum.
WMS allows capturing important information on the items
such as weight, expiration date and more.
Other benefits obtained are that real time radio
communication enables real time stock updating. This in
turn prevents re-picks or waiting time due to empty picking
faces. Cycle counting can built in to the replenishment task,
improving the efficiency of the stock checking process. The
improved accuracy of stock recording leads to improved
service level and less time spent investigation stock
discrepancies.
The provision of information at the website is a good
channel for the distribution centre (DC) to fulfil the needs of
their customers and hence improve customer relationship.
Real-time information eliminates waste and redundancy.
Fill Ratio has been improved from 82.3% to 86.3%. It
increased customer satisfaction resulting from fewer
fulfilment errors. EDI requirements support through WMS
automatically providing detailed shipping information. It
allows for real-time communication and complete visibility
for supply chain collaboration
It was reported that 43% of the customer complaints was
due to warehouse operation mistakes before. Nevertheless,
the operation accuracy has been improved to just 11% of
complaints after implementation.
Efficient planning and utilisation of space delivers
improved warehouse inventory visibility. Making optimal
use of warehouse space is essential to having an efficient
and effective warehouse management system. To
effectively manage the warehouse space, WMS provides the
ability to individually determine for each bin whether it is
fixed or floating. Improved space utilisation was achieved
by logical stocking in different sized products.
WMS also provides detailed audit trail that measures
performance levels objectively, ensures employee
accountability and allows material flow to be easily traced.
It was found that the operations procedures at the
warehouse have been overhauled to adapt to new warehouse
management system. Business Process Reengineering
(BPR) has taken place. Maintenance department was
established for independent cycle counting process. The
WMS promotes knowledge sharing. It is clear the usage of
the logistics system have been embraced at all stages of
operations. The system has fundamentally improved the
warehouse’s services, internal and external relationships
reflected in the performance measures to help the
warehouse gain a competitive advantage. They are able to
alter the way in which the firm conducts its business or the
very business of the firm itself. These flexibility and
enterprise-wide approach has brought real agility to the
business, supporting strong business growth. The bottom
line of a WMS is the ROI it provides. By improving on
warehouse procedures, WMS makes the distribution centre
more competitive and profitable.
There are constraints faced by the distribution centre. For
the demand forecasting, poor demand forecasting processes
can result in excess inventory, stock-out and back orders,
and unable to forecast early-lifecycle and end-lifecycle parts
accurately. In term of inventory management, the
distribution centre experienced limited collaboration into
demand lead to poor inventory deployment, as the result of
lack of integration into sales data. At the lower stream flow
of operation in distribution and logistics, there is challenge
of inefficient distribution flow, logistics and warehouse
management processes that can result in long lead-time
from suppliers to customers and expensive total cost of
distribution. There is also bottleneck created by sub-optimal
processes and lack of end-to-end integration within.
In order to encourage the staff to further embrace to new
warehouse management system, long-term on-going
training is essential, the system must be designed with
regular programme enhancement to create awareness of the
gains of using technologies.
6.0 CONCLUSIONS
To maintain competitiveness, customer requirements are
met consistently, which are achieved by, among others,
enabling of more flexible processes with deployment of
radio-frequency technology, improved scope of delivery
with provision of same day delivery services, shorter
delivery lead time especially airfreight mode, increased
customer satisfaction with less complaints, inventory
visibility with higher inventory accuracy and cost
efficiencies with higher labour productivity while
minimising inventory investment which includes inventory
handling. Procedures have been established to monitor and
measure WMS activities.
It is concluded that WMS has a positive impact on
operations measures. Investments in WMS enable the
distribution centre to compete successfully against other
rivals in the market. To adopt the MIS, wireless barcode
embedded WMS in specific, it is necessary to have
corporate culture that supports complex operational
activities. BPR has to be enacted as such that the WMS and
associated physical operations are well integrated. WMS
implementation was crucial in bringing about reduction of
cost in operational level, and effective management in
management level, as well as improvement of the
company's competitiveness in strategic level. Companies
that manage warehousing of their products are expected to
implement WMS in order to maintain their competitive
edge in the global market place.
The case study is limited to a selected electronics parts
regional distribution centre. The flows analysed are the
physical (stock management and movements) and
informational flows that are associated with the service
parts distribution activities. Future studies may explore on
variety of industries to capture distinction in experience, by
focusing on consumer market based electrical appliances or
perishable fast movement consumer goods (FMCG).
Comparative studies can be conducted across industries, and
then the similarities and differences observed. Alternately,
measurement of intangible benefit can also be tested in
Malaysian industries.

Automation and digitisation are the driving force of the Industrial Revolution 4.0. Industrial revolutions led to the mass production of goods, which increased the need for modern warehouses. Every year, the operation of warehouses becomes increasingly more complicated due to the increasing abundance of goods, thus the usual warehouse management strategies are no longer suitable. In order to cope with huge product flows, modern innovations should be used more extensively to manage these processes. Successful management will help provide quality service to rapidly changing business sectors. The Internet of Things (IoT) is a technology designed to process large amounts of data with maximum efficiency in real time. This technology can facilitate the implementation of smart identification, tracking, tracing, and management using radio frequency identification (RFID), infrared sensors, global positioning systems (GPS), laser scanners, and other detection tools. Such innovations as IoT have made a significant impact on warehousing operations. The aim of IoT is to perform administrative work, i.e., to efficiently manage warehouse data. IoT can be used to monitor and track goods, forecast demand trends, manage inventory, and perform other warehouse operations in real time. The key elements of a warehouse are sales and customer satisfaction. Implementing IoT improves financial performance, work productivity, and customer satisfaction. However, innovation requires additional investment in, for instance, implementation and maintenance. It is necessary to investigate how warehouse elements such as inventory accuracy or order processing time are affected by the internet of things in companies of different sizes. Research on the impact of IoT on warehouse management focuses on IoT advantages, disadvantages, mitigation risks, and the use of IoT in warehouses. The aim of this work is to research the impact of IoT on warehouse management in companies of different sizes and to determine whether the costs and benefits of IoT differ in the same scenario. As a result, the conceptual model for the adoption of IoT measures in warehouse companies was created, and its suitability was assessed by experts.
... WMS is crucial for providing highly effective services and optimizing and automating material and information flows (Hompel and Schmidt, 2007). Au (2009) recommends that companies involved in warehousing deploy WMS to remain competitive in global markets. A growing body of literature has investigated the benefits of implementing a WMS to increase productivity, reduce costs and improve overall customer satisfaction (Autry et al., 2005;Ramaa et al., 2012;Richards, 2017). ...

Purpose The concept of a sustainable warehouse management system (WMS) is a relevant yet under-researched area within warehousing logistics. The purpose of this research is twofold: first, to review the literature on the topic of socially and environmentally sustainable practices; second, to lay the theoretical base for identifying social and environmental sustainability practices in warehousing operations that can serve as focus areas for WMS operational functions. Design/methodology/approach This research built knowledge on a systematic literature review and bibliometric analysis in Scopus Elsevier and Web of Science Core Collection databases. After comprehensively filtering English literature from 2016 to 2024, only 43 out of the initial 601 studies comprised relevant warehousing practices that can be incorporated into the scope of WMS activities. Findings As a result, retrieved practices were allocated to a specifically designed warehouse model within the main processes, equipment and resources. This model could serve as a baseline for incorporating 48 sustainable WMS practices. The prevailing share of practices focuses on environmental rather than social warehouse sustainability. WMS should adopt sustainable warehousing practices to reduce warehouses' carbon footprint, energy and resource consumption and improve working conditions in a warehouse. Originality/value There have not been any existing reviews on warehouses' social and environmental sustainability to synthesize knowledge and serve as a base for WMS sustainability. This research will contribute to developing more sustainable and environmentally responsible warehousing operations, ultimately benefiting society and the environment. By incorporating such practices into WMS, warehouse owners can ensure efforts toward social and environmental sustainability while still maintaining efficient operations.

Warehouse is the part of human existence where everything fits and is appropriate. A warehouse is critical for Connecting many associates in the chain. Regardless of what the supply chain is talking about, it is significantly irrelevant these days. It has become increasingly important to control and allocate warehousing resources. To meet this condition, a new term has been implemented that provides warehouse management systems for managing, noticing, and following warehouse exercises, although due to the changing nature of the market, standard systems have become less useful and preferable. Warehouse management system are highly dependent on the implementation of IoT. This system enables the warehouse chief to maintain more control and better visibility of the workloads. it's now time to study warehouse management systems and the IoT. The promise of IoT is exciting, because it can be used in industry. The IoT layers and squares we are spread throughout the network. Finally, IoT usage in the supply chain and warehouse was investigated, including both advantages and possible setbacks. Using IoT, AI, and ML, one may assist warehouses in performing many significant deeds.

Nowadays, the warehouse acts as a competitive factor in any supply chain as it has a main role in linking all the partners in it. Hence, it has become very necessary to allocate its resources efficiently and manage it effectively. A sound warehouse management system can contribute to cost reduction and improve customer satisfaction. However, traditional warehouse management system models have become unsuitable and inefficient for today's market requirements. So, companies have started to adopt innovative approaches and technologies to be used for such applications; one of these technologies is the Internet of Things that enables the connection between several physical objects and produces a massive amount of real-time data that can be transferred to useful information that helps in managing and decision making. In this paper, the architecture of this application is illustrated, its potential benefits are overviewed, and a framework for implementing this technology in a warehouse is proposed. This system can help in achieving more control and monitoring on all the operations in the warehouse in real time, increase speed and efficiency, and prevent counterfeiting and inventory shortage. The proposed framework can be taken as a roadmap for enterprises to improve warehouses by using the Internet of Things. Also, the benefits of implementing the proposed framework and its challenges are proposed.

The health commodity management information system (HCMIS) has been implemented in Ethiopia to serve the country's public health commodity supply chain management since 2009. But Tikur Anbessa Specialized Hospital (TASH) implemented since 2017. However, there is no evidence thus far on changes in the performance of the warehouse and inventory management practices since the implementation of the HCMIS. Therefore the purpose of study was to assess warehousing and inventory management performance after HCMIS implementation. A quantitative method research design using facility based retrospective technique was applied to survey data for the years (2015/2016 and 2017/2018). The collected data was entered and analyzed using Microsoft excel and statistical package for social sciences (SPSS) version 20 computer software. The current study revealed a significant improvement in order fill rate, line fill rate, inventory turnover rate, stock wastage amount and rate, and order turnaround time with percentage improvements of 14.06%, 4.48%, 42.85%, 50%, 1.25%, and 26.1% respectively following HCMIS implementation. HCMIS has improved the warehousing and inventory management of TASH. However the system needs to be linked to the pharmacy units and fully controlled and managed by the hospital in order to reap the full benefit of the system. Introduction Inventory management is the heart of the pharmaceutical supply system. It informs health facilities when to order or issue, how much to order or issue, and how to maintain an appropriate stock level of all products. All these activities are tracked with appropriate documentation, thus good record-keeping is critical. Generally a good inventory control system result in minimized inventory investment, appropriate customer service level, balanced supply and demand, minimized ordering cost and holding cost; also preservation of inventory control system [1] while poor inventory management leads to wastage of financial resources, overstock of pharmaceuticals, shortage of essential medicines, and a decrease in the quality of patient care [2]. It has been recognized as one of the most important functions that has huge impact on the overall performance [3]. In hospital the second largest expense after employment cost to health care provider is inventories, which usually estimated to consume one fifth of the income from patients [4]. Therefore inventory management constitutes the key lever to realize efficiency improvements (e.g. reduce costs, waste and the risk of product obsolescence) while satisfying healthcare service levels [5]. Warehouse management comprises the physical movement of a stock in to, through, or out of a warehouse. Regardless of storage facility size-from a small health center to a central warehouse the main operational activities for storage are very similar which include receiving, put away, storage, picking and packing, and shipping. Warehouse management should insure productivity, timeliness, use of resource, and safety. As a result, pharmaceutical cost decreased and service level improved. The health commodity management information system (HCMIS) in Ethiopia is an open source, custom software solution; it was developed in Ethiopia for the country's health commodity supply chain by USAID | DELIVER PROJECT. First developed and deployed in 2009 to manage inventories in health facility pharmaceutical stores [6]. As of 2017, the HCMIS plat form has been implemented in more than 700 health facilities that account approximately 80% of PFSA's distribution [7] .
... It self is the right choice for use by companies in various sectors. WMS implementation can reach the inhibition of the storage process and reduce the operating time during the recording process [9], [10] . ...

The Bio-Fertilizer Company is a company that produces liquid biological fertilizer which is sold to farmer groups and communities throughout Indonesia. The company has problems in carrying out the data collection process in the warehouse at the time of production, this happens because the recording process is still done manually, so workers must take longer because the data entered is not systematically arranged. Warehouse Management System (WMS) is a picture that is used to assist a company in improving every aspect related to storage to be well organized. In the process of making a system, researchers use the SDLC Extreme Programming method where the method is suitable for small and medium scale teams. This is to overcome incompatible requirements and change requirements very quickly. The results of this research are in the form of an application that can help business processes, especially the inventory recording of goods in the warehouse. Before the use of the system, the recording was still done manually so that the data previously recorded using paper was not arranged neatly which caused the data was not in the right order, so from these problems it was hoped that the implementation of the new system using the warehouse management system could help overcome the problems is in the company.

This chapter examined how the use of technology in inventory control impacts organizational performance since inventory is the most valued asset of an organization. From the summary of this study, it can be concluded that the adoption of technology as RFID in inventory management leads to improve the organizational performance in both financial and customer responsiveness. In the business performance , RFID could improve the organizational performance in terms of reducing inventory carrying costs on the warehouse, such as lowering the expiring cost of the product stocked, increasing space in a warehouse, avoiding exceed inventory, and decreasing labor costs. Moreover, from the perspective of customer service, the adoption of RFID could increase customer responsiveness in terms of reducing stock out risk, increasing the accuracy of product delivery, and increasing the interaction between customers with the organization.

The aim of this study is to identify factors that improve the performance of integrated supply chains (SCs). We developed the 'extended strategic alignment model' based on the literature on next generation supply chains, supply chain management, and the role of IT and business architectures. The model was used to do in depth analysis of the Unitech worldwide SC for high-tech handheld scanning devices. During 1995-2002, the business architecture, power relations, and IT architectures in the SC changed considerably. We found a high increase of overall SC performance, intensifying relationships with local Taiwanese and European companies, and continuous IT developments. There was no SC wide planning of IT infrastructures and no IT-driven strategy to improve SC performance. No shared SC performance measures are used; in fact, in each company SC performance is measured from a perspective limited to one or two tiers in the SC. Originally, the Taiwanese company had a dominant position in the SC. Over the years, downstream companies increased their power position, without any of them having a clear control system for the integrated SC.

This study examines a series of relationships between information technology (IT) and business process reengineering (BPR). Specifically, it argues that those aspiring to do business process reengineering must begin to apply the capabilities of information technology. This paper provides a summary of IT roles in initiating and sustaining BPR and examines several companies that have successfully applied IT to reengineering. The paper also addressees barriers to successful implementation of reengineering and identifies critical factors for its success.

Purpose To review the development of software applications and their functionalities/benefits in relation to supply chain management and present scenarios on future development. Design/methodology/approach A range of recently published academic and non‐academic pieces of work that can be classified as pertinent to the area in question. These sources employ both theoretical and practical views on the topic of supply chain co‐ordination software and related functionalities and resulted benefits. Findings There is a significant overlap regarding the functionalities of software applications and the trend of convergence is about to intensify. At the same time the need for real time information will become crucial, putting emphasis on flexible IT‐systems that can deal with large amounts of data and are easy to interconnect. In turn this will lead to the growing importance of system integration software and the process of creating standards. Research limitations/implications As a result of continuous development and convergence of IT‐solutions and turbulent business environment more applied research will be needed in the area of product configuration, RFID‐technology, standards in relation to interoperability of software applications (EAI technologies). This scrutiny is based only on written resources and no consultants or manager interviews were employed. Therefore the views of companies are not presented on the issues covered. Practical implications The selection of the appropriate software solutions for a company will need more time, expertise and money and the role of suppliers of software packages will become more significant. Originality/value This scrutiny stipulates the way the functionalities of software applications evolve with overlap one another and thus helps both researchers and companies to gain a clearer view on the development of supply chain software applications.

This paper investigates linkages between information technology (IT) and firm performance. Although showing recent signs of advance, the existing IT literature still relies heavily on case studies, anecdotes, and consultants’ frameworks, with little solid empirical work or synthesis of findings. This paper examines the IT literature, develops an integrative, resource-based theoretical framework, and presents results from a new empirical study in the retail industry. The findings show that ITs alone have not produced sustainable performance advantages in the retail industry, but that some firms have gained advantages by using ITs to leverage intangible, complementary human and business resources such as flexible culture, strategic planning–IT integration, and supplier relationships. The results support the resource-based approach, and help to explain why some firms outperform others using the same ITs, and why successful IT users often fail to sustain IT-based competitive advantages. © 1997 by John Wiley & Sons, Ltd.

Many current and future distribution systems cannot tolerate data capture delays found in periodic batch processing and reporting of inventory quantities, their locations and movement. The increased inventory accuracy and timeliness of real-time data permits the whole spectrum of activities of suppliers, sales and distribution personnel and customers to be performed with confidence and improved profitability. One method of real-time data collection is via bar-coding, scanning and two-way radio frequency (RF) transmission. This provides a “wireless connector” to the host computer no matter what type of items are being manufactured and/or distributed. RF systems integrate the technologies of automatic identification systems (AIS), bar-coding, automatic data capture (ADC) and enhance electronic data interchange (EDI) and quick response (QR) systems. Together with other subsystems, manufacturing and distribution firms are better able to control inventory operations and compete more effectively in servicing domestic and international customers.

Recent work in social theory departs from prior traditions in proposing that social phenomena can be understood as comprising both subjective and objective elements. We apply this premise of duality to understanding the relationship between information technology and organizations. We construct a theoretical framework in which the development and deployment of information technology in organizations is a social phenomenon, and in which the organizational consequences of technology are products of both material and social dimensions. The framework is based on Giddens' theory of structuration, and it allows us to progress beyond several of the false dichotomies (subjective vs objective, socially constructed vs material, macro vs micro, and qualitative vs quantitative) that persist in investigations of the interaction between organizations and information technology. The framework can be used to guide studies in two main areas of information systems research- systems development and the organizational consequences of using information technology.

Common foundations which underlie thinking in the supply chain management (SCM), Business process re-engineering (BPR) and business process improvement (BPI) philosophies are highlighted. The view that BPR is a new concept is argued against by highlighting die work performed in other fields, namely SCM from the systems perspective. It is argued that those who have already implemented the SCM philosophy will have already travelled the same path as BPR and indeed re-engineered their own processes. Once businesses have integrated their supply chain the greatest benefits will have already been achieved, however system dynamics analysis does show significant on-cost differences dependent on the redesign strategy implemented. A generic structured model for SCM is enhanced through this comparison with BPR with the following characteristics being added; do not be afraid to be radical with respect to internal integration and continually search for step change improvement ideas which can be strategically phased in to positively impact the marketplace.

After several years of use of electronic data interchange (EDI) in various industries, the literature is still inconclusive regarding the benefits gained from its usage. We investigated contextual factors of two types: non-managerial (product diversity, product customization, production instability, and organizational size) and managerial (just-in-time and quality management), that might have confounded past results. Our results indicate that the extent of EDI use is significantly related to delivery performance after controlling for the above-mentioned factors. Furthermore, the data set supported the moderating effect of production instability on the relationship between the extent of EDI use and delivery performance achieved, but failed to support the moderating effect of organizational size.

The development, implementation and ownership of information systems, especially large-scale systems such as enterprise resource planning (ERP), has become progressively longer in duration and more cost intensive. As a result, IS managers are being required to justify projects financially based on their return. Historically, information systems have been difficult to quantify in monetary terms because of the intangible nature of many of the derived benefits, e.g. improved customer service. Using the case study methodology, this paper examines an attempt by a large computer manufacturer to incorporate intangibles into traditional cost–benefit analysis in an ERP project. The paper reviews the importance of intangibles, lists intangible benefits that are important in ERP projects and demonstrates the use of a scheme through which they can be incorporated into traditional evaluation techniques.

Supply chain management often requires the integration of inter- and intra-organizational relationships and coordination of different types of flows within the entire supply chain structure. Inter-company integration and coordination via information technology has become a key to improved supply chain performance. Recent advances in information technology enable firms to manage effectively and inexpensively the coordination of not only the physical flow of materials but also the flow of different types of information such as demand, capacity, inventory, and scheduling, through a supply chain. Despite its importance, little attention has been given in the literature to the issue of measuring the magnitude and the effectiveness of available information that logistics information systems provide. This study provides a generic measure to show how well or to what degree a firm is integrated or “coupled” with the members of its supply chain structure from an information flow system perspective. The measure, called degree of supply chain coupling (DSCC), is a 2-tuple index which takes into account both the intensity and extent to which information about demand, capacity, inventory, and scheduling is shared and used by the firm in both directions of the supply chain. We indicate several productive practical uses of the DSCC measure at both macro and micro levels.
