Why efficiency of employees is not measured and nobody gives the feedback to the employee himself? When you are an athlete, you cannot do anything now without being tracked on all your moves and activities. And you have access to everything to help you understand and improve yourself. This should be the same in your job! Problem is that a company is a hierarchical organization where not everybody has a gentle attitude toward others. So people are afraid about judgements. The solution is to deliver metrics in a confidential way, only the person itself has access to his data, nobody else in the organization. Organization itself can aggregate data in a anonymous way to have a global picture.
