Towards Structured Flexibility in Information Systems Development
Method configuration is a specific type of Method Engineering (ME) that takes an existing organization-wide Information Systems Development Method (ISDM) as its point of departure. Existing assembly-based ME approaches are not well suited to this task. As an alternative, this paper suggests a metamethod approach to tailoring organization-wide ISDMs. We refer to this approach as the Method for Method Configuration (MMC). MMC takes into account the need to combine structure, which is one reason for choosing an organization-wide ISDM in the first place, with flexibility, which is essential for making the chosen ISDM fit actual projects. The metamethod is built using a three-layered reuse model comprising method components, configuration packages, and configuration templates. These concepts are combined efficiently to produce a situational method and thereby to facilitate the work of method engineers.
