The main purpose of this thesis is to contribute to anincreased feeling of security and confidence in the process of making a sound choice of a standard system. We started our work with a theoretical study in order to learn about systems, in particular standard systems; methods, in particular methods in information systems development and methodological knowledge i.e. methods from a knowledge perspective. Further on, we assembled a tentative view of the unbalance between our need for knowledge and our accumulated knowledge.Relevant theories, i.e. methods relating to the field ofstandard systems evaluation, were analyzed and combined by method-fragments. This resulted in, by our means, a confident and secure meta-architecture for standard systems evaluation. We empirically tested the meta-architecture at OSS Sales that needed professional aid in making a sound choice of a standard system for request handling.
