There is a wide gap between the users and the developers in terms of understanding an information system. The most important job scope of a system analyzer is to interview the users to fulfill the requirements and to produce the documentation in layman terms. Chaos theory, system dynamics, project management theory, etc. all tell the initial stage playing an important role during system development. If the users¡¦ requirements are not clearly understood, it will have a bitter consequence when the information system is online. Therefore, system analysis is the essential stage for changes and to understand the requirements of the users.
Currently, approaches of system analysis are related to either database management or structured methodology. As for the acquisition of users¡¦ requirements, there are no clear steps and procedures. This has made the understanding of users¡¦ requirement more difficult. We hope that by using a tool of architecture, system analyzers can better comprehend users¡¦ requirements. Hence, we come up with the Architecture-Oriented-System-Analysis-Model (AOSAM) for analysis, design, implementation and testing of an information system.
For this research, there are three portions: (1) the fundamental theory of the AOSAM, (2) the build up of the AOSAM, and (3) procedures of using the AOSAM. In this study, we find out AOSAM is able to combine structure with process during the system analysis stage. Furthermore, AOSAM also reaches three significant accomplishments: (1) system analysts grasp users¡¦ requirements firmly, (2) system designers easier to transform users¡¦ requirements to design documents, and (3) to reduce repeating System Development Life Cycle. In the future, we would like to advance the AOSAM to the area of user acceptability, integrated business information system, system design, etc.
