Another great feature is the Resources Breakdown Structure (RBS) to define the structure of the resources, teams, providers, etc. Task Usage and Resource Usage are features to control your project and provide a good track on it. The Report tool provides information about the current status of your project. OpenProj provides tools to open at the bottom of the window and provide different views of the project at the same time; Histogram, Chart, Task Usage and Resource Usage are the tools that you can open at the bottom of the window to have a better perspective of the advance or delay on you r projects.

OpenProj was developed at Projity by Marc O’Brien, Howard Katz and Laurent Chretienneau in 2007. It moved out of beta with the release of Version 1.0, on January 10, 2008.
In late 2008, Projity was acquired by Serena Software. As of early 2009 support for OpenProj and communication about development of OpenProj seem to have been suspended. There were actually regressions with a few commits to the CVS, There has been no improvement in the past four years and it is not longer compatible with Microsoft Project.
