1. Introduction
Supply chain :
– traditionally, emphasizes on the connection, transaction, and delivery of services
– nowadays, the focus shifts to meet market demands rapidly, correctly, and profitably
– How to achieve this new goal?
• Through the help of
– 1. Technology, and– 2. Quality-driven capabilities
• e-logistics is a system which enhances such an objective
• e-fulfillment – is an e-ERP system, or Extranet– also refers as an web-based B-B e-logistic
system
2. Objective of the study
• To determine the success factors of web-based e-logistics
3. Design of study
a. Data collection procedure
b. Data analysis
b. Data analysis
• Four main tests were adopted:
i) construct validity
ii) reliability test
iii) exploratory factor analysis
iv) SERVQUAL measure
(refer to the paper for these clear definitions)
This paper adopted the following methods for data analysis:1) Construct validity. This paper adopted KMO (Kaiser-Meyer-Olkin) values to measure
the adequacy of the samples (Black & Porter, 1996). KMO values are typically usedto judge if a group of decision variables is suitable for analyzing as the successfactors when the exploration factor analysis method is used. The KMO value of 0.5 isconsidered to be acceptable condition (Kim & Mueller, 1978).
2) Reliability test. This paper adopted internal consistency method to test if a set ofdecision variables in a cluster is homogeneous. A reliability coefficient
³ 0.6 in a
cluster is considered as sufficient condition to conclude a high consistency of decisionvariables (Nunnally, 1978).
3) Exploratory factor analysis. This paper followed xxx(decision science) to performfactor analysis of decision variables with each factor. A general guideline is that avalue of factor loading
³
± 0.5 for a decision variable is considered as practically and
significantly contribution to that factor (Hair, 1987).4) SERVQUAL measure. This paper adopted the SERVQUAL measure as shown in
Kettinger and Choong (1997). The service quality of Intranet can be measured bycomputing firstly Intranet Perceptual scores by subtracting values of IntranetPerformance scores from Intranet Expectation scores. Gap correlation is thenobtained by studying the correlation of Intranet Perceptual scores with the OverallIntranet User Satisfaction scores.
a. Data collection procedure
3 main steps:
1. Conduct a literature survey to collect decision variables
2. Construct a questionnaire
3. Samples selection
Steps:1. Conduct a literature survey to collect decision
variables that relating to e-fulfillment• here, the examination of a B-B system, such as
Intranet is highly depended upon• A total of decision variables is identified
Steps:2. Construct a questionnaire based on part (1)
• two measurements are collected for each decision variable
– a) their expected performance in a scale of 5
– b) their actual performance in a scale of 5
Fill out by e-logistics/MIS manager
Fill out by their trading partners a value 5 representsmost important/ highlyagree; where as 1 appliesto the vice versa case
Steps:
3. Samples were selected from the web of http:www.tdctrade.com
• 380 samples were randomly selected
• 105 returned with two missing data
• 103 replies used for data analysis– response rate is 27.6%

5. Further Discussion and Conclusion
Four critical success factors are identified:
1. System quality (6 decision variales)
2. Information quality(3 decision variables)
3. Service quality(3 decision variables)
4. Work performance quality(6 decision variables)
We further to examine if these four CSF can be used to discriminate the good and poor performance of their e-fulfillment systems, it is shown that the the good performers would do a better job on the following two CSF:– a. System quality– b. Work performance quality
In this paper, we identified:– 18 decision variables– 4 critical success factors– 10 decision variables significant to overall
performance– 2 critical success factors, exercise more by the
good performers
