Audited planning profile
This freelance three-year profile applies a 1.5× editable baseline across 36 model periods to the habit building buffer model.
Use the buffered result for planning and the unbuffered result as the transparent baseline. Separate personal and business costs, unpaid time and tax reserves. Run an adverse case for inflation, downtime and changing demand over three 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.
