Building reports that get read · lesson 2 of 4
Building a utilisation report step by step
In this lesson
- Build a utilisation report from data selection through to a shareable view
- Choose sensible groupings and a comparison baseline before formatting anything
A utilisation report answers a simple underlying question - how much of people’s available time is being used on billable or planned work - but a first attempt often turns into a wall of numbers because the grouping and baseline were never decided before the formatting started.
Decide before you build
Two decisions matter more than any visual choice: how you are grouping people, and what you are comparing utilisation against. Get these wrong and no amount of chart styling will make the report useful.
- Choose the time period. Weekly is usually too noisy for a recurring report; monthly, rolling over a quarter, is the common default that smooths short-term variation without hiding a real trend.
- Choose the grouping. By team, by grade, or by practice area - pick the one your reader actually manages against, not the one the data makes easiest to slice.
- Choose the baseline. A target percentage, last quarter’s figure, or both. A utilisation number with nothing to compare it to tells the reader almost nothing.
- Build the underlying view. Select the data source, apply the time period and grouping, and add the baseline as a reference line or column before any formatting.
- Sanity-check one figure. Pick a team or person whose utilisation you already know roughly, and confirm the report shows something close to what you expect before trusting the rest.
- Format last. Only once the figures check out should you adjust visual presentation - chart type, colour, layout - for the audience this report is built for.
Why the baseline matters most
A report showing “utilisation: 74%” with nothing else is not yet informative. Is 74% good? Against an 80% target, it is a shortfall worth discussing. Against a 65% target, it is ahead of plan. The comparison, not the raw figure, is what lets a reader decide whether anything needs their attention, which is the entire purpose of building the report.
Sanity-checking before you trust it
Before sharing a first version of any report, find one figure you can verify independently - a team you know well, a person whose recent project you can recall - and check the report’s number against your own sense of reality. Grouping errors and date-range mistakes are common on a first build, and they are far easier to catch on one familiar figure than after the report has already been circulated.
Key takeaways
- Decide the grouping and the comparison baseline before touching visual formatting
- A utilisation figure is only meaningful next to a target or a prior period
- Build the view, check it against a number you already trust, then format
