Component-based application systems offer the flexibility to effectively support frequently changing processes as they can be easily assembled of component variants most suitable to accomplish a task in a certain moment. This paper introduces two extreme types of configuring flexible application systems: pre-configured application systems and just-in-time configured application systems. As a prerequisite to component-based applications, a component repository and its meta schema are presented. Workflow Management Systems are proposed to control – beside the business processes – the construction processes.enText/Conference Paper1617-5468
