Connecting Organisational Needs to Workforce Planning

Lesson objectives

Translate a simplified work demand into a capability requirement with explicit assumptions and calculation.
Distinguish numerical, capability, and timing or distribution gaps.
Compare workforce-gap responses rather than equating workforce planning with recruitment.

Workforce planning starts with required capability, not vacancy counts

Workforce planning connects changing organisational needs with the people strategy. CIPD describes planning as balancing demand for labour and skills against the available supply of people and skills, then examining gaps. The question is therefore not only, “How many people should we recruit?” It is: What work is expected? What capability is required? What do we have now? Where is the gap in number, skill, timing, or distribution?

From demand to supply to gap

A gap can be numerical, but it can also be a capability gap: enough people may be present while a required skill is missing. It can be a timing or distribution gap: capability exists but becomes available after the need, or sits in the wrong location or shift. These categories are teaching tools that prevent “number of people” from being confused with “usable capability.”

Item	Case value	Meaning
Expected demand	1,200 requests/month	Work volume to plan for in the scenario
Planned capacity	150 requests/analyst/month	Productivity assumption for the calculation; it should be monitored in practice
Numerical supply	7 analysts	People available for the same work in the scenario
Numerical gap	1 analyst	8 calculated as required minus 7 available
Capability-gap example	3 people need complex-case capability; 2 have it	The shortage is a specific capability even if total headcount is sufficient

Scenarios are better than one precise number when the future is uncertain

Once a gap is clear, compare responses rather than jumping directly to recruitment: simplify the work or remove low-value activity, redeploy work, develop current people, move capability from another team, recruit, or use temporary support where appropriate. Compare readiness time, cost, risk, effect on other teams, sustainability, and the experience of affected people.

Exercise

Exercise 1: A team expects 900 requests per month, current capacity is 150 requests per person, and it has five people. Calculate the requirement and gap. Then assume a process improvement raises capacity by 10%, from 150 to 165 requests per person. Recalculate and explain the result without turning it directly into a recruitment decision.

Check your answer

Guided solution: the first requirement is 900 ÷ 150 = 6 people; with five available, the numerical gap is 1. After improvement, capacity is 165 and the requirement is 900 ÷ 165 ≈ 5.45; in the simplified whole-person scenario, 6 people are still required to cover 900, so the numerical gap remains one. The improvement reduces spare capacity needed within the period but does not change the whole-person count here. A real decision would also examine whether capacity is sustainable, whether quality is maintained, and what other constraints apply.

Lesson summary

Workforce planning balances demand for work and skills with available supply and identifies the type of gap. Calculations use explicit assumptions, then scenarios test sensitivity and response options are compared on time, cost, risk, and impact.
