In my blog on Aligning Archimate to BPMN – I introduced the idea of creating process overviews, such as this one: In a high level design I don’t expect to see fully defined processes. Such a decision quite often gets made in a meeting, maybe minuted and dropped into an email and forgotten about. Within any solution or service design there are normally many meetings, and its essential we track decisions that are made in a single space that is available for all.
