Organizational Complexity Index

TL;DR

A diagnostic heuristic inspired by fractal dimension that relates organizational size to hierarchical depth.

A diagnostic heuristic inspired by fractal dimension that relates organizational size to hierarchical depth. Measures structural complexity to identify over-branching or under-branching pathologies.

When to Use Organizational Complexity Index

Use as a quick diagnostic when evaluating organizational structure, comparing divisions or business units, or benchmarking against industry norms.

How to Apply

1

Map Hierarchy

Document organizational hierarchy from top (CEO) through all branches to individual contributors.

Outputs

  • Org chart
2

Count Parameters

Count total hierarchical levels (L) from CEO to frontline. Count total employees (N).

Outputs

  • L (levels)
  • N (employees)
3

Calculate Index

Compute complexity index: D ≈ log(N) / log(L). Example: 10,000 employees with 5 levels gives D ≈ log(10,000)/log(5) ≈ 5.7

Outputs

  • Complexity index D
4

Interpret Results

Compare to benchmarks: D ≈ 3-4 suggests efficient structure; D > 5 suggests overly complex hierarchy (too many layers); D < 2 suggests excessive flatness (too wide span, low oversight).

Outputs

  • Structural diagnosis
