The official business definition of an IT project timeline is a document that outlines the scope, timeline, and objectives of a particular IT project. It is an essential tool for project managers and other stakeholders to ensure that the project is completed on time and within budget. The timeline typically includes the project’s start and end dates, milestones, and any other key dates related to the project. It also includes a detailed description of the tasks that need to be completed, the resources required, and the expected outcomes. The timeline is also used to monitor progress and identify any potential risks or issues that may arise. By providing a comprehensive overview of the project, the timeline helps to ensure that the project is completed successfully and within the expected timeframe.
