I don't know. It occurs to me that if a very large organization wanted to make necessary changes to its infrastructure within a reasonable time limit, say 18 months or so, it might bring in bright, motivated contractors to audit each organizational component and make timely recommendations in order to fulfill the mission within the specified time frame.
If that organization attempted to do it internally, within its own bureaucracy, it might take decades. I don't think it unusual to give it more than a few weeks to start evaluating results before deciding which way is better.
