Program Evaluation and Review Technique
(PERT) with ConceptDraw DIAGRAM

PERT method (Program Evaluation and Review Technique) is developed by the Ministry of Defense of the USA in 1958 in the framework of the project Polaris. PERT diagram is one of the tools for project management. With its help it is possible to analyze the time which is necessary for project execution and the consequence of tasks which involved into the project. The main advantage of such diagram type over the other diagram types is the possibility of calculation of the project fulfillment critical path that is the consequence of tasks which has the minimal float for execution and on which the total time for the whole project execution depends. If the task on the critical path is delayed than the execution of the whole project is delayed. There for it is important to calculate the critical path of the whole project execution and pay the most attention to tasks which appear on this way.

PERT Diagram is a more realistic approach of a project's time estimate analysis. After PERT chart was constructed user can discover the shortest possible duration for entire project timescale. The project timeline is the longest chain that might be taken with connected tasks on the PERT Diagram. Completion of serial tasks need to be accomplished in a presented order. At a project timeline can be independent tasks that not linked with main sequence they are called parallel tasks. PERT diagram is more suitable for Critical Path Analysis than Gantt chart for the reason that it undoubtedly better figure task dependencies. Project managers customarily utilize both methodologies.

It should be considered that PERT diagram does not give you ready concrete decisions but it helps you to find these decisions.

PERT diagram is constructed by definite rules. It represents the set of tasks, connected between each other in the consecution of their execution.

PERT benefits:

  • With a PERT method users can decide how to split project phases and choose the tasks' specification and dispose relations between them.
  • Different contractors involved in the project can coordinate the work on their tasks.
  • PERT determines schedule based on the availability of resources assigned to project tasks.
  • Decrease completion time of different tasks or supposed additional actions.
  • PERT utilizes resources within flexibility for implementing a thrift.
  • Attracting more management attention to critical stages of the project.

There are two variants of PERT diagram construction. In the first variant the duration is denoted on arrow connecting diagram nodes. Such diagram type is called AOA (activity on arrow).

The second type of PERT diagram is called AON (activity on node). In such diagram the information about the task duration is denoted in the diagram node and each task is represented in the form of rectangle with the definite set of fields. These are the task name, duration, early and late starts and early and late finishes of the task and also the float for execution of the given task.

With the help of ConceptDraw you can build diagrams of any type, but we recommend you using of AON variant, because such diagram type is easier for building and perception.

PERT diagram starts from the task which does not have duration and does not use resources and presents just a project start. This is done to denote the common start of the project as starting from the first day of the project several tasks are starting simultaneously. Analogously PERT diagram finishes with the task “finish”.

No task is able to start before the preceding task is finished. Also each task may represent a separate project with its subtasks, which can be displayed on a separate diagram. In ConceptDraw this can be realized in the form of hyperlinks assigned to such tasks. These hyperlinks may point at some pages of your ConceptDraw document where the corresponding PERT diagrams are placed.

Objects for PERT diagrams building are gathered in a separate ConceptDraw objects library. To start working it is enough to launch PERT Chart template from ConceptDraw STORE.

To create a PERT diagram with ConceptDraw, it is enough to drag on a document page the number of ready objects, representing tasks, and then connect them between each other and fill out necessary task fields.

However, a Gantt chart gives more information than PERT diagram, and that assume to expand the information on it:

  • activity name
  • normal duration time
  • early start time (ES)
  • early finish time (EF)
  • late start time (LS)
  • late finish time (LF)
  • slack

Task appeared on the calculated critical path are marked out with red color. This way any person is able to see at once tasks which require special attention.

Process Flowchart →

When trying to figure out the nature of the problems occurring within a project, there are many ways to develop such understanding. One of the most common ways to document processes for further improvement is to draw a process flowchart, which depicts the activities of the process arranged in sequential order — this is business process management. ConceptDraw DIAGRAM is business process mapping software with impressive range of productivity features for business process management and classic project management. This business process management software is helpful for many purposes from different payment processes, or manufacturing processes to chemical processes. Business process mapping flowcharts helps clarify the actual workflow of different people engaged in the same process. This samples were made with ConceptDraw DIAGRAM — business process mapping software for flowcharting and used as classic visio alternative because its briefly named "visio for mac" and for windows, this sort of software named the business process management tools. This flowchart diagram shows a process flow of project management. The diagram that is presented here depicts the project life cycle that is basic for the most of project management methods. Breaking a project into phases allows to track it in the proper manner. Through separation on phases, the total workflow of a project is divided into some foreseeable components, thus making it easier to follow the project status. A project life cycle commonly includes: initiation, definition, design, development and implementation phases. Distinguished method to show parallel and interdependent processes, as well as project life cycle relationships. A flowchart diagram is often used as visual guide to project. For instance, it used by marketing project management software for visualizing stages of marketing activities or as project management workflow tools. Created with ConceptDraw DIAGRAM — business process mapping software which is flowcharting visio alternative or shortly its visio for mac, this sort of software platform often named the business process management tools.Process Flowchart
