When Gantt Charts Fail: Use Flag Charts to Show Upcoming Events
You’re probably familiar with Gantt charts, which show project tasks, their duration, and their completion dates. For a specific project, project managers and executives use Gantt charts to quickly review upcoming activities.
When reviewing a portfolio of projects, project managers sometimes continue to use Gantt charts, adding upcoming tasks for all projects to a single chart and sorting by task start date. These consolidated Gantt charts are sometimes referred to as ‘key event maps’, because they show key events across a portfolio.
