Worst: almost no business deliverable is one tenth as important as the people telling you to give up your time, strength and sanity in order to achieve it will tell you that it is.
I’m always amazed by how irrelevant the objectives produced by business planning processes can be. It’s so common to hear things like, “yes, we know this won’t ever end up in a product, but it’s in our objectives, so we have to focus on it”. The task was leviathan and impossibly complex, so it doesn’t get accomplished, and then every quarter the goals focus on a smaller piece of this until the group delivers some result, which is celebrated internally but now obviously irrelevant to the business, so everybody gets laid off, except the people that set the objectives in the first place. Yeah, you can easily pour your life into something that is completely meaningless, even to the company that is paying you to do it.
