Audited planning profile
This personal five-year profile applies a 1× editable baseline across 60 model periods to the project deadline breakeven model.
Compare the break-even period with the time you realistically expect to keep or use the option. Use inputs from the individual who will bear the cost, time or resource commitment. Treat maintenance, replacement and compounding assumptions as material over five years.
Interruptions, dependencies, holidays and human variability must be added to the editable inputs or buffer.
Compare the estimate with recent actual completion times and reserve capacity for interruptions.
