In “Back in History” is stated that an approach, in which the organization-dependent groupings of business elements are strictly separated from those groupings that are organization- independent, offers an effective starting-point for the design of a systems architecture.

The subsequent paragraphs state, that the elaboration of each of the distinguished aspect groupings following the Interactive Model Architecture approach, leads directly to the most flexible functional structure. Further on, this structure can be translated to any technical architecture, based on technical, economical and 'political' considerations.

As can be seen the presented approach pre-eminently fits to an evolutionary systems development strategy.
