Why measure?
Here are 10 reasons why even a seemingly innocuous activity such as time management must be supported with a good measurement system:
Metrics provide insight: Metrics such as productivity and efficiency are not mere data points or facts. By evaluating and analyzing these metrics, it is possible to identify strengths and weaknesses.
Metrics set expectations: For example, historic values for productivity and efficiency measures set the standard for future productivity and efficiency. They can help predict and track use of time.
Metrics allow budgeting: Complementing the previous point about expectations, metrics not only set expectations but also set limits. For example, the expectation that a task would take two hours would allow you to set aside that amount of time, that is, budget the time, when planning for the task.
