Capacity Planning

Part of the workforce planning cluster. This is educational, operational guidance that connects to the wider site — the employee lifecycle, employer operations, metrics and templates.

It is forward-looking: most useful as a planning lens, not just a record.

Why it matters

Persistently over-capacity teams burn out and lose people; under-capacity teams carry cost without output. Capacity planning makes the trade-off visible and actionable.

It connects forecasting and headcount strategy to real, day-to-day load.

Key concepts

• Realistic available capacity (not theoretical max).
• Required capacity from planned work.
• Headroom for variation.
• Distribution of load, not just averages.

Operational framework

• Estimate realistic available capacity.
• Estimate required capacity from the plan.
• Compare and keep deliberate headroom.
• Look at distribution, not just totals.
• Feed gaps into hiring and prioritisation.

Common challenges

• Using theoretical maximum capacity.
• Aiming for 100% utilisation.
• Averaging away uneven load.
• Reading capacity only backwards.

Best practices

• Use realistic available hours.
• Keep healthy headroom.
• Watch load distribution.
• Use capacity to time hiring and prioritise.

Common mistakes

• Planning to a theoretical maximum.
• Treating full utilisation as the goal.
• Ignoring uneven load.
• Only looking at the past.

Measure this with the workforce capacity metrics metric, put it into practice with the workforce planning template, and run it as a system via workforce capacity planning.
