However, it is difficult for a subcontractor to get a point of contact with a customer newly. It is because the problem of trust has separated the customer and the subcontractor. The agent site appeared in such environment. The site which utilized the Internet solves the trust problem. It has tried formation of the opened reliable market. Special skill is unnecessary in order to use the site. Moreover, the charge of use of the site is relatively cheap. Although it is small IT investment, it is guessed that a subcontractor is worked as a contractor. This is a big impact.

In IS development there are two ways of creating work systems: adopting external best practices and constituting by self-reference. Self-reference is supposed to reveal a variety of discourses and practices in the realities of an organization. ISD methodologies are widely used whereas methodologies for work system development are not. We need frames and cues to make sense of social realities. However, the shortage of a construct for capturing cues makes it difficult to use the frames. We will introduce, as a construct, collective identity that is currently paid growing attention by sociologists and political scientists, and discuss that it is effective to articulate the social realities.

Purposes of IT in enterprises have become strategic. Hence, it becomes important in IT investment evaluations to make agreement among the three kinds of stakeholders, a manager, a business unit, and an IT unit. In this paper, we propose an IT investment evaluation method using transparent models to quantify benefits financially and support this agreement making. Additionally we describe the method from viewpoints of processes, entities and organizations. We define entities such as inputs, references and outputs at each process step and organization roles of each process step. Through its application to investment projects, it is demonstrated that proposed method is effective in making agreement.

Data that are processed and stored by information systems should meet requirements of users. From this point of view, an information system can be seen as a production system of information used by users. Its objective is to supply requested information to the requesting user at the requested time as easily and inexpensively as possible. "Requested information" here is information that satisfies quality requirement. We argue information quality from the stand point that quality requirement should be characterized by information users, then propose a possible system development cycle where information system is assessed based on information quality and quality improvement is aimed at.

This model of inner information cost enable to explain explicitly interaction between productivity of information cost and mechanizing on division of labor.
