Two metrics answer different questions
Productive utilization shows how much available time contributes to valuable work. Billable utilization shows how much available time directly generates client revenue.
A healthy organization needs both. Billable utilization without productive investment can damage capability; productive utilization without enough billable work can weaken margins.
Use targets as guidance, not punishment
Targets should reflect role, seniority, and responsibility. A delivery specialist may carry a higher billable target than a practice leader who supports sales, coaching, and operations.
- Set targets by role rather than one company-wide number
- Exclude approved leave and public holidays from capacity
- Review trends over several weeks
- Investigate the work behind the variance
Explain the movement
Reporting should connect utilization changes to their causes: delayed projects, time off, internal initiatives, missing timesheets, or unfilled demand. A percentage becomes useful when a manager knows what action can change it.
