The Legibility Tool

Describe the shape of your organisation and see the Expected Operating Level its structure typically demands.

As an organisation grows, the way it holds control has to change with it. Proximity works while everyone is within reach. Beyond that point, control has to be built into the architecture of the business. The Legibility Tool gives you a structural benchmark for where your organisation should be operating, so you can compare it with where it actually is. Guidance on counting Business Units and Functions is built in, and nothing you enter is stored.

Scale and footprint

Total people employed across the business.

Physical sites or offices where work is done. Minimum 1.

How much of the work is delivered by the business itself versus outside providers.

Structure
How to count Business Units

Count a unit only if it has its own leader (GM-equivalent) and a meaningful subset of its own staff, strategy, regulatory exposure and process ownership. The deciding test is strategic independence: does it pursue its own external market, or exist to serve the rest of the business? Enter 1 for a single-unit business.

  • Included: a genuine subsidiary, international entity or business line with its own leadership, staff and external customers.
  • Excluded: Enterprise Management and shared services (HR, IT, Finance, Legal), always.
  • Excluded: dormant or pass-through subsidiaries, and call centres running one function under many scripts.
  • Excluded: identical product lines sold under different brands. These count as product lines instead.
How to count Functions

Take the total from your Functional Area › Functional Group › Function decomposition. A Function shared across Business Units counts once.

Within Enterprise Management, count HR, IT, Finance and Legal separately only when each has its own system and specialist ownership. An owner personally coordinating several outsourced providers counts as one Function.

Product-line count adds load to functional complexity rather than acting as a dimension of its own.

A note on the model

This is a legibility tool, not a measure of complexity. Its weights and thresholds are provisional and are being refined against real cases. Treat the result as a benchmark to prompt reflection and conversation, not a verdict.
