How much is too much information?
We've all encountered people who share more than you wanted to know about their pet peeve or what have you. While we get through the encounter by nodding our head and making appropriate noises while figuring out an escape strategy what happens to enterprises whose architecture team gets caught in a never ending exercise of documenting the current state? The EA initiative probably goes up the chopping block as the powers that be cannot figure out what value EA is providing.
James (2006) in the Gartner article Just enough current-state architecture assesses the optimal level of current state documentation. James advocates iterative implementation of architecture and recommends developing the future state architecture first and to then document enough of current-state architecture to identify the gaps between it and the future state to plan for the migration. Organizations should heed this in order to focus on the value providing initiatives of the enterprise.
