Outside effect and project boundaryUse justifies the System concept, while the useful change may cross the assumed boundary.
Several environment Systems and one simple storyA compact scenario helps reasoning, while one hierarchy can hide non-nested participants and affected Systems.
Function and feasible bearerRequired functioning guides concept development, while a function word or diagram does not supply a bearer.
Working descriptions and physical groundingModels and scenarios keep claims inspectable, while their form does not establish use, transformation, architecture, or evidence.
Early usefulness and completenessOne linked claim can expose the next question, while a fixed comprehensive form delays learning.
Continuing revision and decision stabilityUse and concept claims must change with evidence, while each downstream architecture question needs a stated current basis.
