100%What's as interesting though, is the calculation methodology. Every firm seems to have its own differences e.g. whether utilisation is calculated on billing-based, time-based, or weighted for both. Some firms adjust the baseline (the denominator in the utilisation equation) for holidays, while others presume 365-day working.For example, I used to have utilisation calculated based on 40 billable hours a week, even though my employment contract was only for 35 hours. This year we've switched from billing-weighted calculation to a purely time-based equation - it makes like-for-like comparison between years (let alone other firms) tricky.
