A library turns individual frameworks into a system. Methods are organised by purpose — strategy, innovation, operating model, transformation — and connected so one output feeds the next. Versioning keeps everyone on the current model. Curation keeps quality high.
For enterprises, a methodology library is the difference between institutional method and personal habit. It captures how the organisation intends to work and makes that intent available to every team. For advisory firms, it is the productised core of their expertise.
