This project timeline infographic is a visual list of tasks or activities organized chronologically that allows project managers to see the entire project plan in one place. A project timeline is typically represented by a horizontal bar chart, with each task given a name and a start and end date. Timelines for project management can take many different forms, with varying degrees of effectiveness. They can be drawn by hand or on a whiteboard, but this method is rigid, and significant changes to your project may necessitate scrapping the entire timeline. A spreadsheet loaded with macros can result in a very capable, albeit time-consuming, timeline. A project timeline excel template can help you save time and money.
