features include ability to link tasks using a drop-down menu, Task Summary Name field, timeline bar labels and task progress, accessibility improvements. Versions for Windows were released in 1990 (v1.0), 1992 (v3.0), 1993 (v4.0), 1995 (Project 95, v4.1a), Project 98 (v8.0), Project 98 SR-1 (1999), Project 2000 (v9.0), Project 2000 SR-1 (2001), Project 2002 (v10.0), Project 2003 (v11.0), Project 2007 (v12.0), Project 2010 (v14.0), Project 2013 (v15.0) and Project 2016 (v16.0). There was no Version 2 on the Windows platform; the original design spec was augmented with the addition of macro capabilities and the extra work required to support a macro language pushed the development schedule out to early 1992 (Version 3). Features The project creates budgets based on assignment work and resource rates. As resources are assigned to tasks and assignment work estimated, the program calculates the cost, equal to the work times the rate, which rolls up to the task level and then to any summary tasks and finally to the project level. Resource definitions (people, equipment and materials) can be shared between projects using a shared resource pool. Each resource can have its own calendar, which defines what days and shifts a resource is available. Resource rates are used to calculate resource assignment costs which are rolled up and summarized at the resource level. Each resource can be assigned to multiple tasks in multiple plans and each task can be assigned multiple resources, and the application schedules task work based on the resource availability as defined in the resource calendars. All resources can be defined in label without limit. Therefore, it cannot determine how many finished products can be produced with a given amount of raw materials. This makes Microsoft Project unsuitable for solving problems of available materials constrained production. Additional software is necessary to manage a complex facility that produces physical goods. The application creates critical path schedules, and critical chain and event chain methodology third-party add-ons also are available. Schedules can be resource leveled, and chains are visualized in a Gantt chart. Additionally, Microsoft Project can recognize different classes of users. These different classes of users can have differing access levels to projects, views, and other data. Custom objects such as calendars, views, tables, filters, and fields are stored in an enterprise global which is shared by all users. Editions The project is available in two editions, Standard and Professional; both editions are available either
