    EA maturity models EA maturity models Presentation Transcript

    • Enterprise Architecture(EA) Maturity Models
    • What EA Maturity Models exist?
      There is no standard model for EA Maturity
      TOGAF refers to US Doc ACMM
      As of July 2011, I found the following EA Maturity Models in the following categories: -
      This presentations focuses on these models
    • Common Traits for all EA Maturity Models
      Most are modelled on the Capability Maturity Model Integration (CMMI)
      The model has a number of levels(from 4-7) of maturity
      Each level has an attribute or characteristic that can be rated based on the maturity of the activities performed by the EA function
      Some models make recommendations in what are the areas of improvement
      Some provide tools to help assess your maturity
