Work out span of control instantly with clear inputs, formula shown and shareable results.
Span of control is non-managerial staff divided by managers, and it drives layer count: at a span of eight, 640 people need only four layers. Comparing your actual layers with the number the target span implies quantifies the excess hierarchy, and layers are what create distance and slow decisions.
Average span
Span = (Total employees - Managers) / Managers
Layers implied by target
Implied layers = ceiling of log(Total employees) / log(Target span)
Excess layers
Excess = Actual layers - Implied layers
6-10 for professional work, 15-25 for standardised operational work, and 3-5 where the manager is coaching complex judgment-based work.
Because promotion to manager is used as a reward, creating managerial roles that the work does not require. Dual career tracks address this.
