Frequently asked questions
What does the Assumption Tracker calculate?
Maintains a register of market assumptions, supporting evidence, test status, owner, and next decision. It uses only the evidence and assumptions entered in the form.
How should I choose the input period?
Use one recent, representative period and keep every count, duration, cost, or percentage aligned to that same period.
Is the result a guarantee or professional opinion?
No. It is a planning estimate or decision signal. Validate legal, safety, financial, or technical decisions with an appropriately qualified person.
When should I update this assumption tracker result?
Recalculate when the scope, evidence, capacity, constraints, prices, dates, or customer segment changes materially.
