Headcount trajectory modelling
See how the shape of the workforce changes across a planning horizon under stated assumptions.
— Organisation & Workforce
Models how a workforce is distributed over time under stated assumptions, computing the movement across a planning horizon.
1 week → ~10 minutes
For one complete, review-ready pass

— USE CASES
See how the shape of the workforce changes across a planning horizon under stated assumptions.
Change an assumption and re-run to see what actually moves.
Produce a written model with the formula and assumptions recorded.
— HOW IT BEHAVES
The mechanics behind this specific template — what it reads, what it calculates, and where a human stays in the loop.
The figures are computed by formula in the run, so the arithmetic is identical every time and can be checked.
Findings are written up as a document that reads like professional output rather than raw model text.
Material is assessed against explicit criteria you control, so the same standard is applied on every run.
The run works from documents and data you supply, so conclusions are anchored to your evidence rather than to general model knowledge.
Every organisation & workforce team needs workforce scenario model — and almost none of them do it the same way twice. In practice it shows up as headcount trajectory modelling: see how the shape of the workforce changes across a planning horizon under stated assumptions. It is the kind of work that decides whether a recommendation survives scrutiny — and the kind that quietly eats 1 week of senior time whenever it comes round.
Skillsize turns that work into a Skill: you supply the material, and what comes back is a computed workforce distribution over time, with the formulas and assumptions behind it. The judgement is built in — how items are broken up, what standard they are held to, and where the run stops for a human review. In effect, 1 week of senior time compresses into ~10 minutes — and the output is comparable across clients, quarters and colleagues instead of shaped by whoever ran it.
Workforce scenario model exports as a structured SKILL.md file and is MCP-ready, so the same method runs in ChatGPT, Claude, Copilot or your own AI products. Adapt it to your methodology, and the intelligence stays yours — not locked to one vendor.
Workforce Plan
Builds the core workforce plan by comparing what a strategy requires against current workforce and skills evidence, expressed as roles and capability gaps.
Workforce scenario comparison
Runs gap analysis for base, upside and downside workforce scenarios against org and skills evidence, bucketing and comparing what changes between them.
Restructure scenario
Models restructure options, computing structural and cost implications of each and scoring them against the current state on your chosen criteria.
