Audited planning profile
This conservative monthly profile applies a 1.2× editable baseline across 12 model periods to the task list change model.
Use the absolute difference for budgeting and the percentage difference for comparing impact. Use this profile when protecting downside matters more than optimizing the headline result. Align the inputs with the actual billing, income or operating month.
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.
