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.
Critical path analysis is commonly used with all forms of projects, including construction, aerospace and defense, software development, research projects, product development, engineering, and plant maintenance, among others. Any project with interdependent activities can apply this method of mathematical analysis.
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
X-Pert supports the full cycle of project management – through multi-level work breakdown structure creation, transition to multiple projects using critical path diagrams and Gantt chart presentation. X-Pert is available as Software as a Service (SaaS) running in the cloud, for a low monthly subscription
The PERT distribution is a special case of the four-parameter beta distribution. The uniform distribution or rectangular distribution on [a,b], where all points in a finite interval are equally likely, is a special case of the four-parameter Beta distribution.
PERT chart for a project with five milestones (labeled 10–50) and six tasks (labeled A–F). There are two critical paths, ADF and BC. A somewhat different DAG-based formulation of scheduling constraints is used by the program evaluation and review technique (PERT), a method for management of large human projects that was one of the first ...
The Gantt chart: Still accepted as an important management tool today, the Gantt chart is a graphical format that is used for the planning, scheduling, and controlling of work, including recording the progress of a project and its stages. The chart has a modern variation, Program Evaluation and Review Technique (PERT).
FFBDs are one of the classic business process modeling methodologies, along with flow charts, data flow diagrams, control flow diagrams, Gantt charts, PERT diagrams, and IDEF. [3] FFBDs are also referred to as functional flow diagrams, functional block diagrams, and functional flows. [4]
