"Always remember that when someone on your team makes a mistake, it is first of all your personal mistake. You hired that person, you trained him or her, you delegated the responsibility, and you controlled and monitored the job. Then he made a mistake, and the project lost money, disappointed a customer, or damaged the firm's reputation. Of course you need to take necessary disciplinary actions and maybe fire the troublemaker. But first of all, you have to admit in front of everyone that it was your personal mistake. You didn't control enough, you didn't plan well, or you didn't take preventive actions. A strong manager isn't afraid to look stupid in front of the team. A weak manager does look stupid when he or she tries to hide mistakes that have been made."
