nine in ten or one in a thousand; your task is the same. - Ben Horowitz

Training is, quite simply, one of the highest-leverage activities a manager can perform.

If you have a great and loyal executive, how do you communicate all this? How do you tell her that despite the massive effort and great job she is doing today, you might fire her next year if she doesn’t keep up with the changes in the business? When I used to review executives, I would tell them, “You are doing a great job at your current job, but the plan says that we will have twice as many employees next year as we have right now. Therefore, you will have a new and very different job and I will have to reevaluate you on the basis of that job. If it makes you feel better, that rule goes for everyone on the team, including me.

Companies execute well when everybody is on the same page and everybody is constantly improving. In a vacuum of feedback, there is almost no chance that your company will perform optimally across either dimension. Directions with no corrections will seem fuzzy and obtuse. People rarely improve weakness they are unaware of. The ultimate price you will pay for not giving feedback: systematically crappy company performance.
