A significant body of information systems research is concerned with user participation as a means to improve user satisfaction within systems development. In spite of the many studies in this area, findings are not consistent or cumulative. One of the reasons for this is not to be considered the type of systems. Most research are focusing on traditional system development under the mainframe environment instead of under end-user based environment like web-based information system or ERP. End-user based environment requires user's strong initiatives in the system development life cycle. It means the user\`s simple participation is not enough and user-led-development is more appropriate for the system success. This paper can call this new concept is end-user joint work which means user has to participate in the system development as a co-developer. This paper investigates how the end-user joint work contributes end-user satisfaction and two variables in particular-job complexity and technical competence-moderate the outcomes of end-user joint work Analysis of 112 independent systems development projects indicated that end-user joint work has a direct relationship with end-user satisfaction. In addition, the two variables were found to moderate key roles on this relationship. That is, the strength of this relationship depended on the level of these factors.

The main theme of this research is a case of e-Business implementation in part manufacturing industry, especially in a PCB manufacturing company. The characteristics of part manufacturing industry are as follows. First, an ERP system runs as a legacy system that is ready to be combined with e-Business system. Secondly, the number of customers is very small. The customers are not many individuals but only a few big electronic enterprises that are strategically affiliated with the part manufacturing company. This means that the e-Business of the part manufacturing industry needs to focus on sharing pertinent information throughout the transactions with the customers, not on data-warehousing or data-mining customers' potential needs or requests. In this paper, we extracted e-Business opportunity domains from a PCB manufacturing company, a typical part manufacturing industry. We are intended to enhance information sharing between customers and the company, and provide functions of transactions necessary in the whole value chain from order to shipment. Implementing the e-Business system on the Web can increase the visibility of customers, and further, the company can be transformed into an extended enterprise where the relationship with the customers becomes very close and interleaved. Also, the Cyber Office functionality of the e-Business system can support the salespersons effectively, so that they can spend more time on customer satisfaction. Such efforts, in the future, can be a basis for active adaptation to the industry transformations such as forming e-community and participating in the marketplace.

In recent years, the main concerns of enterprise management activities is how to strengthen the competitiveness to quickly respond to changes and sustain the growth in business environment. In order to achieve competitiveness and sustainability, a large variety of production informatization systems, such as MES (Manufacturing Execution System), ERP (Enterprise Resource Planning), have been introduced to manufacturing companies. However, there have been many problems owing to the reckless introduction of those systems. Therefore, it is necessary to evaluate the informatization level of the manufacturing company before introducing production informatization systems. This paper presents methodology and system to evaluate the informatization level of manufacturing company. The proposed evaluation method, based on the traditional questionnaire approaches, considers the various characteristics of the company. And then, we proposed models for calculation and production informatization level using 450 results of conducting a survey. Finally, a web-based system was developed for the evaluation of informatization level.
