Amy Esselman wants to know if you’re on time or have any slack:
A Gantt chart is used to visually present tasks or events over time. It consists of a horizontal axis of time and horizontal bars representing the duration of each item arranged along the vertical axis.
The visual was popularized in the early 1900s by American engineer and management consultant Henry Gantt, for whom the chart is named. Most commonly, this view is used to see the start date and duration of each task in a larger project to better understand timelines, milestones, and dependencies.
