Definitionv1DF-188
Assumption register
a written, persistent document that records all significant assumptions underlying a plan or decision, including their importance, uncertainty, validation status, and next actions for testing or monitoring
Why This Is a Definition
This definition precisely establishes the semantic boundary of 'assumption register' by specifying its nature as a written, persistent artifact that records multiple components (assumptions, importance, uncertainty, validation status, next actions). It distinguishes it from casual assumption listing by emphasizing persistence, structure, and the systematic approach to tracking. The definition is precise enough to distinguish from other documentation methods and aligns with the curriculum's emphasis on external cognitive infrastructure.
