Long but well thought through editorial.
Certainly very valuable when managing business expectations of IT work. I've had the experience of someone saying "It shouldn't take 3 months to do xyz" or "It's been 3 months and nothing has been accomplished" whereas the reality is that lots has been done and even delivered, but because it hasn't yet met the exact (and ever-changing) expectations of the person or didn't turn out to be as useful as they thought it would be, it counts for nothing. I can see it's very valuable in those situations to push back and emphasis what has been accomplished and why that's important.
For myself, I know if I have a day filled with meetings and I don't accomplish something tangible on my own, I feel like I "accomplished nothing".
