1. Estimate the core work
Enter the hours required if the work proceeds without rework or interruptions.
2. Set daily focus capacity
Use the amount of concentrated project time available on a typical workday.
3. Apply an efficiency rate
Reduce nominal focus time for ordinary friction such as messages and small interruptions.
4. Add rework and buffer
Use rework for extra labor and buffer for schedule uncertainty.
5. Use the rounded workday result
Place that many working days between the start and target dates.
