A utilization target is the explicit answer to "what share of our billable people's time should be billed?" — the number that staffing, hiring and pricing decisions key off. Without one, utilization is a report you read; with one, it is a variable you manage.
For agencies and dev shops a sustainable target sits in the 70–85% band for delivery roles. The gap to 100% is not waste — it is where wrong estimates, internal work, pre-sales support, learning and ordinary human slack live. A plan that targets higher spends that buffer in advance, so every surprise lands directly on overtime or a deadline.
Using a target well:
- Set it per role, not company-wide. A senior who carries pre-sales and mentoring realistically bills less than a mid-level delivery engineer; averaging the two hides both signals.
- Manage against the forecast, weekly. By the time a low month appears in a report the hours are unrecoverable — the useful comparison is next week's planned allocation against the target.
- Read sustained deviation as a signal. A quarter above the band is a hiring trigger; a quarter below is a sales or bench conversation, person by person.
In Helia, live utilization comes from the capacity matrix — billable people on billable projects, net of approved time off — with a 12-week forecast, so this week's number and the coming weeks' trajectory are held against the target before the month closes, not after.
