Definitions
Workforce Planning. Workforce planning is deciding what people and structure an organisation needs — roles, numbers, timing and capability.
Capacity Planning. Capacity planning compares the work people can realistically do against the work the business needs done.
Similarities

Differences
- Scope — workforce planning is broad (roles, structure, capability); capacity planning focuses on workload vs availability.
- Output — workforce planning yields a hiring/structure plan; capacity planning yields a strain/slack view.
- Capacity planning is one input to workforce planning.
Use cases
- Use workforce planning to translate goals into roles, structure and timing.
- Use capacity planning to check whether current and planned people can meet the load.
- Feed capacity insight into the workforce plan.
