Project Timeline is a visual presentation of a chronological sequence of project events or jobs placed along a drawn line that enables project team members to quickly understand temporal relationships between scheduled events or jobs. It is a way to arrange project activities by the time constraint through using illustrative visual material that brings the activities arranged chronologically, by priority and by execution order.
A timeline for a project serves as a basic tool to define, measure, and track durations of project events and activities. A project manager can use this tool in developing job schedules and job calendars. In order to develop a comprehensive project timeline, the manager needs to use the following inputs:
- Number of workdays required for completing project tasks
- Task execution order and task priorities
- Task dependencies
- Parallel or simultaneous tasks
When the manager provides these inputs, he/she can create a timeline and thereby get the following outputs:
- A scheduled sequence of events that are associated with respective project tasks
- Event start time and finish time
- Event durations as well as the total project duration
- A representation of temporal relationships between scheduled events.
