Soft Systems Methodology (Checkland)
Uses root definitions and a comparison cycle between a rich picture of the mess and a conceptual model to surface whose purpose and worldview the system serves, then iterates toward accommodation rather than settling any single structure.
Peter Checkland, 1981
The origin of the framework, as the directory records it. The mark grades the origin, not this page.
Umbrex, Soft Systems Methodology (Checkland)
The directory entry this score was read from. Umbrex is a consultancy network; its summary is the reference, not a primary source.
Scored against the twelve cells, it loads two: Purpose and Learning. The other ten it leaves to you. None of Composition, Evidence, or Mastery is among them, which is the usual result in this directory: the questions an agent in the loop raises first are the ones the literature answers least.
This is not a summary of the framework. Umbrex has one; the link under Sources goes there.
What orients a person and an agent when neither can see the whole system?
How does tacit judgment become reusable, and who owns the loop that has to close?
