What Is a PERT (Program Evaluation Review Technique) Chart? A PERT chart is a project management tool that depicts the chronology of a project graphically. The Program Evaluation Review Technique (PERT) deconstructs a project's separate activities for study. Then, using statistical analysis tools, such as linear programming, it estimates their completion dates and completes a chart showing how long each activity will take to complete.
A PERT chart shows the probability that each activity will be completed on or before its estimated date. For example, an activity with a 50% chance of being completed by its estimated date has a PERT score of 1.0. If no time limit is given, then the activity has no deadline and thus has a PERT score of 0%.
The PERT method was developed by William E. Peterson in 1978. He presented his findings at the University of California, Berkeley, where it is now used by project managers throughout the world.
In a PERT chart, each activity is represented by a bar across the chart. Activities that can be done in parallel are separated into different projects. Projected completion dates are shown next to each bar. The length of each bar represents the project's estimated duration. At the end of the bar, there is a line called a projection curve which indicates what percentage of activities have been completed per week or month.
The Program Evaluation Review Technique, or PERT, is a visual tool in project planning that assists companies in analyzing and representing the activity, as well as evaluating and estimating the time necessary to finish the project on schedule. PERT was developed by Bill Pert, who worked for the Boeing Company during the 1970s.
Pert starts with a question mark (?), which represents the unknown factor of the project. Then, you estimate how long it will take to complete each task using a percentage value. Finally, you add up all the estimated task durations to get an overall project duration. If any task takes longer than expected, you adjust the other tasks' estimates accordingly so that the whole project finishes on time or early if possible.
Some advantages of using PERT are its simplicity and ability to visualize the project timeline. Disadvantages include its accuracy only when used properly and the fact that not all projects can be analyzed using this technique.
Here are some examples of tasks performed by a project manager: create a detailed project plan, determine the resources needed to complete the project, interview participants to identify any potential challenges or issues with the project, maintain accurate records of progress, submit periodic reports to higher-ups regarding project status, and so on.
A PERT chart is a visual project management tool that is used to lay out and track a project's activities and schedules. PERT stands for Project (or Program) Evaluation and Review Technique. The technique was developed by E. Jerome McCarthy and Thomas Porter in the 1970s.
The PERT chart consists of five main parts: planning, scheduling, executing, monitoring and controlling. Each part is divided into several tasks that can be completed at any time during the life of the project. Tasks are linked together with start dates and end dates. When an end date is reached, a task terminates. Projects usually have a defined length of time; therefore, each part has an ending date after which new work cannot be started unless there is no longer any hope of completing the project by this date.
During the planning phase, the goals of the project are determined. Then, the tasks needed to complete the project are identified. Finally, estimates are made for how long it will take to complete each task. Using these estimated completion times, a schedule is created that shows when each task should be done. This is the planning stage of the PERT chart.
Next, the project is monitored and updated as necessary during its execution. Tasks that aren't expected to finish until later than the project end date are moved to the next phase.
Technique for Program (Project) Evaluation and Review (PERT) It is a visual project management tool that is commonly used in project planning. It entails planning, coordinating, integrating, and authorizing unpredictability. The term "pert" was coined by John Zachman in 1980 when he presented PERT to a group of managers at the Stanford University Business School.
Zachman later introduced the concept into popular culture with a cartoon character he created named "Dr. PERT". Dr. PERT first appeared in a 1981 issue of Management Science magazine where he was described as a "human reliability expert".
He has been called "the father of modern project management".
PERT is a registered trademark of the Project Management Institute (PMI).
Applications of PERT: Planning, scheduling, executing, monitoring and controlling processes or projects - especially those involving risk.
Does PERT apply only to projects in business? Yes. However, it is widely used by non-profit organizations, government agencies, and educational institutions as well.
Who invented project management? There are several claims to this honor, but the most common one goes to Sir David Wheeler who published the first book on project management in 1947.
