Rediscovery of Pattern Language from an Information Systems Viewpoint

Software engineering yielded the big fruits of the Design Patterns and POSA and so forth by using the Pattern Language of architectonics, but they only focused on the side of the format of the pattern as know-how description. Focusing on another side of the Pattern Language—"timeless way" as continuous activities—we can see that the Pattern Language is an ideal mechanism to incorporate the requirements and the design constraints of information systems into itself as organization learning. In this paper, "The Information Systems Cycle" is provided for the building process of the enterprise information systems from such a viewpoint, and the meaning and the problem of incorporating the Pattern Language into the cycle are discussed
