# Roles and ranks as one system

Every role has a forest; every forest has ranks; every person holds skills at levels. Run across the whole organisation, this becomes a single system with answers HR and leadership usually have to improvise.

**"Is this person ready for the next rank?" — a defensible answer.** They hold the skills that define the rank at the required levels, or they don't. Promotion committees stop debating impressions and start checking a map both the person and their manager have been looking at all year. "Defensible" matters: the same evidence that convinces a committee protects the decision afterwards — to the person promoted, to those who weren't, to anyone auditing fairness across teams.

**Roots as the promotion and hiring bar.** What someone must already know to enter a forest is *derived* from the skills' own prerequisites, not guessed by whoever wrote the job description. The same derived bar serves both doors: hiring from outside and moving people across roles inside.

**One organisation-wide view of capability.** With shared skill definitions and a common level scale (chapter 6), forests aggregate. Leadership can see where the org is thin, where single points of failure span *teams* — the skill that three departments each assume some other department owns — and who across the whole company is near their next rank.

**Sideways visibility.** Where forests overlap, the map shows where people can move laterally and what they'd need to pick up — turning internal mobility from a lucky accident into something you can actually plan.

The compounding effect is the point: each team's honest map is useful; all the maps together, speaking one vocabulary, are an organisational capability the org never had before — the ability to *see itself*.
