Mesa/VistaPM - Version 1.1 If you use Microsoft Project, Mesa/VistaPM is for you! Mesa/VistaPM allows you to share and navigate all your project schedule data over an intranet or an extranet. Easily publish, navigate, and report on project, task, and resource information. Forget about those wall-size Gantt charts that are out of date the day you tape them all together -- pan, zoom, and navigate from the charts, all from the convenience of your web browser.
