Audited planning profile

This household daily profile applies a 4× editable baseline across 1 model period to the daily commute buffer model.

USE THIS PROFILE TO

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

DECISION RULE

Use the buffered result for planning and the unbuffered result as the transparent baseline. Use household totals and include irregular shared costs rather than only one person's spending. Use a typical day and separately test peak or exceptional days.

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.
