Absolutely. I left that part out, but if there is something I need to change to do my job better, I most certainly do that as best as I can. The thing is that those conversations have never been directly tied to metrics.
Of course, they're almost always very qualitative discussions. If you have a track record of discussing improvement points, hopefully both you and your manager will be able to agree that any metrics that might appear during year end reviews are mostly extraneous.
