We've developed a Microsoft Excel tool to help you manage your projects with RACI and Gantt Charts. Feel free to download, share and use it as you wish (just remember to give us the credit)!
You will need to enable macros for the file to work.
Fill out your project plan, then click "Update Charts" to update both Gantt Charts. (The Gantt chart on the "Project Plan" tab does not print. The "Gantt Chart for Print" tab will print a clean, full-page chart.)
To change the size of the printable Gantt chart, simply change the page size or orientation from the "Page Layout" tab in the ribbon.
Enjoy. And let us know what you think!
