Duration in Project Management – Definition and Meaning

In project management, duration refers to the estimated or actual total time span required to complete a specific task, work package, or entire project. It is used to create, manage, and monitor the project schedule. Duration is typically measured in time units such as working days, hours, or weeks, and defines the time from the planned or actual start to the planned or actual end of an activity, often accounting for non-working periods such as weekends or holidays.

Example, best practice, and further information

In a software development project, the estimated duration for the testing phase of a particular software component might be set at 5 working days. A best practice is to estimate activity durations realistically, considering resource availability, dependencies, and potential risks. This aligns with time management techniques in the PMBOK Guide and with the planning of agile iterations or sprints. Careful estimation of duration helps to create realistic schedules and minimize the risk of delays.
