I'm now on the side of the table where I frequently make personnel decisions: hire, promote, offer a new role, offer a new assignment, merit adjustment, expand a successful team, disband or merge an unsuccessful team into another, transfer in, transfer out, put on a PIP, etc. Most of the good things on that list go to people who demonstrate ability and results, and rarely do those results come without effort. Most of the bad things on that list go to people who demonstrate an inability to deliver results, which is sometimes related to a lack of effort.
