Microsoft Project, commonly abbreviated as MSP, MSOP or WinProj, is a project management software program, created and sold by Microsoft, which is intended to support a project manager in developing plans, managing budget, analyzing workloads, assigning resources to tasks and tracking progress. MS Project was the company's third Microsoft Windows-based application, and within a couple of years from its release, it became the dominant PC-based project management software. Microsoft Project 95 was the first to use common Office menus. Although branded as a member of the Microsoft Office family, it never has been included in any of the Office suites, like Visio. It is available presently in two editions, Standard and Professional; both editions are available either as 32 or 64bit options. MS Project's owned file format is .mpp. Microsoft Project and Microsoft Project Server are the foundations of the Microsoft Office Enterprise Project Management (EPM) product. Microsoft Project 2010 features the Ribbon user interface.
