This week's reading on Maturity of EA was quite detailed and informative. The fact that any concept or thing becomes stronger and well established as it matures is clearly conveyed in the readings on EA Maturity.
In the book - Enterprise Architecture as Strategy, with the help of a simple example of the 'Big Dig' project at Boston, the authors explain at depth about the various stages of maturity that EA in an organization goes through. The four stages are -
1. Business Silos Architecture
2. Standardized Technology Architecture
3. Optimized Core Architecture
4. Business Modularity Architecture
Organizations are required to move through each of these stages in order to successfully adopt EA and exploit its complete functionality. An organization at stage 4 of EA maturity would be the one that the entire industry would look up to. The stages begin from the companies which have many silos (individual entities/units of business). It is not a good idea to have business silos because integration across the different business areas would be very difficult. Silos are individual entities which do not talk to other entities leading to a decentralized system. Moving on, the next higher stage of maturity is to standardize the technology/applications across the organization. This is one step closer to having a centralized system. Next level is standardizing the data and processes of the organization as they form the core or skeleton of business. The last and highest level of maturity is the stage which has the highest amount of business modularity and which enforces the greatest amount of standardization across processes. All organizations adopting EA must aim to reach at this level of maturity and I believe that it is at this stage where all the EA benefits would become clear.
But I think moving the stages of maturity is easier said than done because it involves one big thing - CHANGE! Change is something that people dislike. Although the technology, data and process can be changed for good, but changing the most important resource of organizations i.e. People is a comparatively tougher task. This, I believe is the biggest challenge to improving EA Maturity in an organization and Enterprise Architects must keep this point in mind before introducing any change.
