This is another area where you should have easy answers to the question. Since you have experience as a software development manager, you have already used several different tools to evaluate your team and improve their performance. The interviewer expects you to list the specific metrics you use, such as on-time completion of tasks, the average number of errors or bugs, and the individual's efforts to improve their skills and knowledge. Use these to demonstrate how you mentor, coach, and develop your team to become more effective software coders.
