Enterprise Architecture: Top Down or Bottom Up?
Sometimes folks desire top down, not because they feel that the need for executive buy-in is the right thing but because they believe something will fail and they need cover. The ability to say that you had no say in the matter is a wonderful thing where as bottom-up forces accountability on folks lower in the food chain.
One of the more interesting things is that a person debating top-down vs bottoms-up needs to take into consideration is historically which one has had better results. Of course, top-down has the advantage that even mediocre delivery will be declared success while bottoms-up mediocrity will probably result in throwing daggers. If we ignore the whole perception is reality crowd for a moment and truly think about success, then I think our conclusions would be different.
Below are three atypical IT initiatives appropriately classified and I would like for folks to comment on which one they feel has been more successful.
