Quarterly capacity planning is one of the highest-leverage activities a COO can run. Done well, it aligns the entire organisation on what’s possible, surfaces resource conflicts before they become crises, and gives leadership a clear view of whether the roadmap is achievable with the people and budget available.
Done poorly, it’s a spreadsheet exercise that takes three weeks, produces a plan nobody trusts, and is obsolete by week two of the quarter.
Here’s a practical framework for running a capacity planning process that actually works.
Step 1: Establish Your Baseline Capacity
Before you can plan, you need to know what you have. For each team, calculate:
- Total working days in the quarter (accounting for public holidays)
- Leave and absence buffer (typically 5–10%)
- Overhead allocation (meetings, 1:1s, admin, recruitment — typically 20–30%)
- Net available capacity per person and per team
The output is a simple table: Team → Members → Net Available Days. This is your supply side. It rarely matches the number people assume.
Step 2: Map Your Demand
List every project, initiative, or workstream expected to run this quarter. For each one, capture:
- Which team(s) are required
- What percentage of each team’s time is needed
- Whether it’s a new commitment or a continuation from last quarter
The total demand across all projects, by team, is your demand side. When you put supply and demand side by side, the picture is almost always sobering.
Step 3: Identify Conflicts Early
Look for teams where demand exceeds supply by more than 15–20%. These are your high-risk teams — not because they can’t work hard, but because they’re being asked to commit to more than is structurally achievable. Flag them explicitly.
For each overloaded team, convene a conversation: what can be deferred, descoped, or resourced differently? This is a leadership decision, not a planning admin task — it requires authority to reprioritise.
Step 4: Run Scenarios
Before locking the plan, model at least two alternatives. What does the quarter look like if you delay Project X by six weeks? What if you bring in a contractor for the backend team? Scenario modelling at the planning stage is far cheaper than replanning mid-quarter.
Step 5: Publish and Socialise
A capacity plan that lives in one person’s spreadsheet isn’t a plan — it’s a private forecast. Publish the agreed plan, make it visible to team leads, and review it at your monthly operations cadence. As projects change, update it in real time rather than waiting for the next quarterly cycle.
Common Mistakes to Avoid
Planning to 100%. Always leave a buffer. Unplanned work will arrive — it always does.
Treating teams as fungible. “The engineering team has capacity” masks the reality that it’s the two senior engineers who are over-allocated, not the juniors.
Skipping the demand-side audit. It’s tempting to start with who’s available rather than what’s been committed. Always start with demand — it’s harder to cut than to distribute.
Doing this once a year. Annual capacity plans are useful for headcount forecasting. Quarterly plans are what actually drive execution decisions.
The Payoff
COOs who run a disciplined quarterly capacity process consistently report fewer mid-quarter surprises, better team morale, and stronger delivery predictability. The process takes time to embed — the first cycle is always the hardest — but the compounding return on operational clarity is substantial.
