I feel like this is the problem of, a lot of what I do, although not as cool as the author, and more due to human issues.

I'm always looking for / wondering about valid data representing the problem so that I can measure success.

A little of last and much of this week I've spent addressing a performance problem. At first I was told it was always happening in some specific situation, it very much is not. Then I was told it frequently happens ... nope, maybe 2 to 4 times a day at most.

I think I've managed to track the issue down. I think so, pretty sure? On the other hand this client has a couple performance related issues ongoing and listening to them talk on a conference call... I'm not really sure they differentiate between them. It's very possible my neighbor a few seats away from me is actually addressing "the problem" and I'm chasing ghosts. But the client is too busy to provide good data. Meanwhile this issue "too important" of an issue for us to do nothing and wait, granted ... we might be doing nothing anyway.
