The oversight methods could also stand to borrow a bit from venture capitalists. VCs don’t ask how well a team has stuck to a plan, especially one that was created years ago. They ask what the team has learned since it started implementing the plan. They don’t ask for a report on how many formal requirements have been met on paper. They ask for the results of the latest user tests, and sometimes they log in and use the product themselves. They assume, to quote the agile manifesto, that “working software is the primary measure of progress.”
