Duration
An activity is an operation or process consuming time and possibly other resources. An individual or work team can manage an activity. It is a measurable element of a programme.
The term ‘duration’ refers to the length of time needed to complete an activity. The time period can be determined inductively, by determining the start and finish date of an activity or deductively by calculation from the time necessary to expend the resources applied to the activity.
