Start with a denominator people can explain
For an individual, use billable approved hours divided by available working hours. For a team, sum both values across the same people and dates before dividing. Do not average individual percentages unless every person has identical capacity.
Suppose a consultant has 40 scheduled hours, eight hours of approved leave, and 22 approved billable hours. If leave is excluded from available capacity, utilization is 22 divided by 32, or 68.75%. If the report uses 40 as the denominator, the result is 55%. Neither number is inherently fraudulent; mixing the policies without naming them is the problem.
Write the capacity policy before setting a target
A utilization target without a denominator definition creates performative reporting. Decide how the metric treats public holidays, annual leave, sick leave, training, internal meetings, business development, management duties, and people who join or leave mid-period.
Different roles can have different expectations. A delivery consultant, practice lead, and operations manager do not contribute to client work in the same way. Keep the formula consistent while setting role-appropriate targets. Changing the denominator to make a role look healthy destroys comparability.
- Use each person’s actual working pattern rather than a universal forty-hour week.
- Remove genuinely unavailable time before calculating utilization.
- Keep internal investment visible as a separate category.
- Version policy changes so historical comparisons remain understandable.
High utilization can still hide weak economics
Utilization describes where available time went. It does not prove that the work was priced well, invoiced, collected, or profitable. A fixed-fee project can post high billable utilization while overrunning its budget. A time-and-materials project can log billable hours that are later written off. A team can also sustain a high percentage by postponing training, sales work, and leave.
Read utilization beside realization, project margin, backlog, write-offs, and workload. The combination explains whether the firm is converting capacity into healthy delivery rather than merely keeping people busy.
| Metric | Question it answers |
|---|---|
| Realization | How much recorded billable value survived to invoice or revenue? |
| Project margin | Did the commercial model cover the cost of delivery? |
| Backlog | Is there enough sold work to support future capacity? |
| Allocation | Is upcoming capacity committed before work begins? |
| Write-offs | Which hours were recorded but not charged? |
Use a weekly signal and a longer decision window
Weekly reporting catches missing time and sudden bench periods. Monthly and trailing-quarter views are better for staffing, hiring, and target decisions because they smooth public holidays, leave, and project transitions.
Give managers the inputs, not only the score. A useful report lets them move from a team percentage to a person, project, and approved entry. When a number cannot be traced, debate shifts from the decision to whether the report can be trusted.
