In this chapter, we will look into practical ways to measure time management skills and track the metrics over time to evaluate progress over time.

Peter Drucker said, "If you cannot measure it, you cannot manage it." Therefore, in order to manage time, there must be an appropriate measurement system. In particular, there must be an objective method to track use of time. This chapter covers metrics for productivity, effectiveness, efficiency, punctuality, and on-time completion of tasks.
