Audited planning profile
This freelance quarterly profile applies a 1.5× editable baseline across 4 model periods to the email processing unit model.
Use the per-unit result to compare vendors, formats or operating choices on the same basis. Separate personal and business costs, unpaid time and tax reserves. 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.
