In Pragmatic Enterprise Architecture, I positioned a quote that I like from Gartner, where they suggest that
Just Enough models should be created Just In Time to address the specific (Business Driven Requirements) - Gartner 2005
exploring this further, a lot of time can be spent building artifacts that have little or no impact on business outcome and as such we need to think carefully about how much is built out. I suggested the following 6 steps
- Identify the Business Strategy and Objective
- Establish an EA program/requirement
- Define the "Future State" Architecture (Don't spend too much time dwelling and documenting the past)
- Define the EA Roadmap (Linked to business benefits)
- Establish EA Governance (ensuring measurement and attainment of business priorities)
