Project timelines are an essential part of any successful business venture. They provide a clear outline of what needs to be done, when it needs to be done, and who is responsible for each task. The official business definition of a project timeline is a visual representation of a project’s objectives, tasks, and deadlines. It is a document that outlines the steps, activities, and resources required to complete a project, and the sequence in which they must be completed. A project timeline should include the project’s start and end dates, as well as milestones and other key dates. It should also include the estimated time required to complete each task, and the resources required to complete each task. A project timeline is an important tool for project managers, as it allows them to monitor progress and make adjustments as needed.
