What are Enterprise Architecture Maturity Models benefits and who is using those models?

Enterprise Architecture Maturity Models are used in various context by different public organizations and private companies notably to drive value centric initiatives, improve performance and optimize budget use.

Where are Enterprise Architecture Maturity Models coming from?

The vast majority of renowned Enterprise Architecture Maturity Models (the Enterprise Architecture Maturity litterature and related subjects such as Enterprise Architecture Effectivness) come from the USA and English speaking countries. (The Dynamic Architecture Maturity Matrix, mentioned below, comes from Netherlands and van Steenbergen et al.)

In France, experts may also talk about “Information Systems Urbanization” that can be associated to IT Enterprise Architecture (based on the Club Urba-EA viewpoint) and use an approach called “l’Indice d’urbanisation” which means Urbanization Index.

The Hybrid Enterprise Architecture Maturity Model (HEAMM) is the first Enterprise Architecture Maturity Model created in France but more interestingly, among the various caracteristics it has, it is worth mentioning that this approach combines 100 areas of assessment and development that include Digital initiatives to extend (significantly and meaningfully) the scope of usual Enterprise Architecture Maturity Models.
