Maturity Model

A maturity model is a kind of ladder of stages for organizations. It describes how far a company, a government agency, or a department has already come in a particular area. Typical models have four or five levels. At the lowest level, things happen by chance and depend on individual people. At the highest level, everything is documented, measured, and regularly improved. You can think of it like the belt colors in judo: they don’t say how many fights someone has won, but how solidly they master the fundamentals.

Why companies have their AI maturity measured

Almost every larger company now claims to be doing something with artificial intelligence. This claim is worth little as long as no one says exactly what is meant. A single pilot project in one department is something completely different from a system that handles thousands of customer inquiries every day. A maturity model makes this difference visible and comparable.

For investors, this is interesting because it separates announcements from real progress. For company leadership, it is useful because it shows where the weakest link is. Often this is not the technology. Frequently, what is missing is clean data, clear responsibilities, or employees who can handle the new tools.

Another reason is regulation. The European AI Act requires documented processes and controls for high-risk applications. Anyone at a low maturity level simply cannot provide this evidence. The model then serves as a roadmap on the path to regulatory compliance.

The levels and how they are assessed

Most models trace back to the CMMI, a framework from software development. Its five levels are roughly named: chaotic, repeatable, defined, measured, and optimizing. Chaotic means that success is a matter of luck. Defined means there are written procedures that everyone follows. At the highest level, the organization systematically improves its own processes based on measured data.

Assessment usually takes place along several dimensions at once. For AI, these are often strategy, data, technology, personnel, and accountability. For each dimension, there are questions with points, answered through interviews or questionnaires. In the end, this produces a radar chart that shows strengths and gaps at a glance.

There is an important rule that many overlook: a level is only considered achieved once all requirements of the levels below it have been met. So you cannot be at level four in technology while skipping level one in data. And the highest level is not automatically the goal. For a small company, level three can be entirely sufficient, because every additional level costs extra bureaucracy.

From consulting offers to regulatory requirements

Anyone who reads business news regularly comes across studies with statements like: only twelve percent of companies surveyed reach the highest AI maturity level. Such figures almost always come from consulting firms or software vendors who then sell help. That doesn’t make them wrong, but one should ask who defined the framework.

Maturity models also exist far beyond the field of AI. Well-known examples include models for IT security, for sustainability, or for the digitalization of schools and public administration. When a federal state rates the digitalization level of its schools in stages, the same idea is behind it.

A common misconception is to confuse a maturity model with a quality seal. A high level only indicates that processes are orderly and documented. It says nothing about whether the product is good or whether the company makes money. An organization can have very mature processes and still fail in the market.
