Audited planning profile
This team annual profile applies a 8× editable baseline across 12 model periods to the project deadline buffer model.
Use the buffered result for planning and the unbuffered result as the transparent baseline. Use measured team throughput and include coordination time and unavailable capacity. Include annual renewals, maintenance, taxes and seasonal variation.
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.
