PERT network chart for a seven-month project with five milestones (10 through 50) and six activities (A through F). The program evaluation and review technique (PERT) is a statistical tool used in project management, which was designed to analyze and represent the tasks involved in completing a given project.
PERT chart for a project with five milestones (10 through 50) and six activities (A through F). The project has two critical paths: activities B and C, or A, D, and F – giving a minimum project time of 7 months with fast tracking. Activity E is sub-critical, and has a float of 1 month.
In probability and statistics, the PERT distributions are a family of continuous probability distributions defined by the minimum (a), most likely (b) and maximum (c) values that a variable can take. It is a transformation of the four-parameter beta distribution with an additional assumption that its expected value is

An example of this type of directed acyclic graph are those encountered in the causal set approach to quantum gravity though in this case the graphs considered are transitively complete. In the version history example below, each version of the software is associated with a unique time, typically the time the version was saved, committed or ...

X-Pert is geared to producing critical path method and PERT schedules for major, long-term projects (in one case [1] a duration now approaching 40 years).. Developed by users and contributors to the ICL 1900 PERT mainframe package, X-Pert is one of the few packages still fully supporting the activity on arrow project network process.
A Gantt chart is a bar chart that illustrates a project schedule. [1] It was designed and popularized by Henry Gantt around the years 1910–1915. [ 2 ] [ 3 ] Modern Gantt charts also show the dependency relationships between activities and the current schedule status.
