What it means
Project assumption analysis identifies statements treated as true, evaluates their stability and evidence, and determines the risk created if they prove wrong.
Why it matters
Plans often depend on uncertain beliefs about demand, technology, suppliers, behavior, approvals, capacity, or timing that are not visible as risks.
Practical focus
- Extract assumptions from charters, estimates, contracts, architectures, schedules, and stakeholder commitments.
- Rate importance, uncertainty, validation method, owner, and review date for material assumptions.
- Create risks, experiments, contingencies, or decisions when an assumption is weak or consequential.
- Retain the approved definitions, assumptions, decisions, ownership, exceptions, measures, and change history that demonstrate how Project Assumption Analysis operates in real project work.
- Exercise this failure scenario: A schedule relies on an unverified approval lead time, and the dependency becomes visible only after the planned release window is lost.
Common mistakes
- Using Project Assumption Analysis as a label without defining its scope, owner, decision criteria, and expected evidence.
- Treating a template, meeting, tool screen, or status report as proof that Project Assumption Analysis works consistently in normal delivery.
- Optimizing a single activity while ignoring dependencies, incentives, risk transfer, and the end-to-end outcome.
- Testing only the expected path and never rehearsing this failure condition: A schedule relies on an unverified approval lead time, and the dependency becomes visible only after the planned release window is lost.
