Audited planning profile

This lean quarterly profile applies a 0.75× editable baseline across 4 model periods to the leave plan compare model.

USE THIS PROFILE TO

Turn workload, pace and available time into an explicit schedule or capacity decision.

DECISION RULE

Use the difference between option A and option B; keep the scale and horizon identical for both. Treat the lean scale as a lower-bound plan and test whether essential fixed costs still fit. Check seasonality and any costs that occur only once per quarter.

NOT INCLUDED

Interruptions, dependencies, holidays and human variability must be added to the editable inputs or buffer.

VERIFY BEFORE ACTING

Compare the estimate with recent actual completion times and reserve capacity for interruptions.
