The assumption log captures assumptions (uncertainties taken as true for planning) and constraints (imposed limitations such as budget caps, regulatory deadlines, or fixed technologies). Documenting them provides transparency, enables validation, and feeds risk identification—if an assumption proves false, it becomes a risk or an issue. The risk register (Option B) contains identified risks with probabilities, impacts, owners, and responses; many originate from challenging assumptions, but they are tracked separately. The issue log (Option C) records current problems requiring action now (e.g., a vendor missed a milestone). The change log (Option D) tracks submitted change requests and their dispositions. CAPM fundamentals stress that well-managed assumptions and constraints improve estimate quality and stakeholder alignment. Good practice includes periodically reviewing the assumption log, testing critical assumptions (e.g., pilots, proofs-of-concept), and updating related plans when assumptions are invalidated. This discipline reduces surprises and supports robust decision-making throughout the project life cycle.
