When a project slips, the first instinct is to question effort. Are people focused? Working hard enough? Nine times out of ten the honest answer is: they’re working too hard, on too many things, for too many people — and no single project owner can see the whole picture.
Over-allocation hides in the gaps between projects
Each project manager sees their own slice. Sarah is “40% allocated” to yours, which looks fine. What you can’t see is that she’s also 40% on two other projects and covering a maternity leave. On paper everyone’s reasonable; in reality she’s at 150% and quietly deciding every day whose work slips. That’s not a motivation problem. It’s a math problem.
The chart that sees it coming
Per-person utilization tells you who’s drowning today. The chart that prevents the fire is capacity vs. demand — total committed work against the hours your team can realistically deliver, week by week. When committed demand climbs above the capacity line three months running, you don’t have a scheduling hiccup; you have a date that was fiction from the start. And it shows up weeks before anyone “feels behind.”
Count the hours people don’t have
Real capacity isn’t headcount × 40. Subtract holidays, PTO, the standing meetings, the support rotation, the “can you just look at this” tax. When someone’s out, their utilization on the remaining work rises — and a planner that ignores time off will cheerfully tell you everything’s fine while a key person is on a beach.
What to do when the line goes red
- Move work, not people’s weekends. Find someone of the same role with headroom before you ask for overtime.
- Re-sequence, don’t just re-assure. If demand genuinely exceeds capacity, something has to move out — decide which, on purpose.
- Make the trade-off visible. “To pull this in, these two slip” is a decision leadership can make. Silent heroics is not.
Speed problems are often capacity problems wearing a disguise. Read the capacity line before you question the work ethic — your team will thank you, and so will your dates.
