How to run a spans and layers review: what to measure, how to judge the right span for each team, and how to act on the findings without disruption.
As organisations grow, management structures tend to grow with them, often without a plan. A team lead is appointed to give someone a promotion. A department head adds a deputy. Two years later, decisions pass through more hands than anyone intended, and some managers have one or two direct reports while others have fifteen.
A spans and layers review measures this objectively. It is one of the quickest ways to see whether a structure is helping or slowing the business.
| Measure | What it shows |
|---|---|
| Span of control | The number of direct reports each manager has |
| Layers | The number of levels between the chief executive and the front line, by function |
| Manager ratio | The proportion of employees who manage others |
| Single-report managers | Managers with only one direct report, often a sign of a title-driven role |
| Very wide spans | Managers with more reports than they can realistically support |
Most of this can be produced from your HR system, provided reporting lines are accurate. Checking that they are is often the first finding.
There is no single correct number. The right span depends on the work.
The useful question is not whether a span is above or below an average, but whether it fits the work in that team. A customer service supervisor with twelve agents may be well placed. A head of legal with twelve reports across very different specialisms probably is not.
Look for patterns rather than individual cases.
A review should lead to a few clear decisions, not a wholesale restructure.
Changes that affect individual roles need careful planning and communication. The aim is a structure that works better, not a headcount exercise in disguise.
