Audited planning profile
This small business quarterly profile applies a 12× editable baseline across 4 model periods to the project deadline change model.
Use the absolute difference for budgeting and the percentage difference for comparing impact. Use current business volumes and preserve working-capital and operating margins. Check seasonality and any costs that occur only once per quarter.
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.
