Many companies have been implementing Enterprise resource planning (ERP) systems for their organizational transformation in order to survive and achieve strategic advantages in an increasing competitive business environment. Thus, it is meaningful to identify factors that affect ERP system operation positively. Organizational citizenship behaviors (OCB) are discretionary, extra-role behaviors of employees which go beyond the prescribed formal roles, and are known as to be the contribution factors for organization performance. The purpose of this study is to develop the measurements for the OCB constructs in ERP system context and empirically test the relationships between the OCB construct and ERP system success. The four constructs - altruism, conscientiousness and courtesy, civic virtue, and sportsmanship - and fifteen measurements on the OCB were developed based on previous studies (i.e. Organ 1988) and empirically verified by confirmatory factor analysis. The results of testing the relationships between the OCB and ERP system success show that the OCB have a significant direct impact on the information quality and intention of IT innovation while they have an indirect impact on work efficiency mediated by information quality. This study enhances the OCB model into information system arena and helps better understand the user behaviors of information systems.

ERP systems are comprehensive sorfware packages that seek to integrate the complete range of lbusiness processes and functions in order to present a heuristic perspectives of a firm from a single information and information technlogy architecture. The ERP systems have delicate internal controls with built-in devices. It is known that the delicate internal controls help to enhance the accounting transparency. We empirically investigate the relationship between the ERP systems inplementations and an accounting transparency. In order to measure the accounting transparency differences, we compare the ERP systems implementation firms with firms which did not implement the ERP systems by 6 financial ratios (accruals, net profit margin, operation cash folo to sales, total debt to equity, accounts receivable changes, assets quality). Data are collecte from 135 firms implemented the ERP systems and 135 firms non-implemented the systems (the firms listed in the Korea Stock Exchange). We analyze financial statements from 270 firms for the period 2001-2003 to ezamine the 6 financial ratios differences. The results of 810 firms analyses over the 3-year period indicate that the ERP systems implementation firms show the statistically significant differences in the accrual ratio, the net profit margin ratio, operating cash flow to sales ratio, and total debt to equity ratio from the ERP systems non-implementation firms. But there is statistically no differences between the two groups for accounts receivable changes to sales ratio and assets quality.

This paper proposes a mathematical model for web site service quality evaluation, which first applies analytic hierarchy process(AHP) to determine the weights of evaluation indexes of web site service quality and then analyzes web site service synthetically by means of fuzzy methodology. In this case, experts' knowledge cannot only be used but its subjective component can be eliminated. Hence, the web site service quality can be analyzed and evaluated more reasonably. After establishing this model, the experiment results will be given, which verify the feasibility and validity of the proposed model. The model proposed here is very simple and easy to implement and can provide a useful way to help developers evaluate their web site service quality efficiently.
