Audited planning profile
This lean one-time profile applies a 0.75× editable baseline across 1 model period to the task list change model.
Use the absolute difference for budgeting and the percentage difference for comparing impact. Treat the lean scale as a lower-bound plan and test whether essential fixed costs still fit. Include setup, transaction and end-of-use costs in a one-time decision.
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.
