  • Lukong Terence Cameroon i need indepth lessons with vivid examples to better understand the notion of PERT or network diagrams as the case may be ...

    • George Fragos Greece PERT breaks down the project into events and activities, and lays down their proper sequence, relationships, and duration in the form of a network. Lines connecting the events are called paths, and the longest path resulting from connecting all events is called the critical path. The length (duration) of the critical path is the duration of the project, and any delay occurring along it delays the whole project. PERT is a scheduling tool, and does not help in finding the best or the shortest way to complete a project.

  • Je Rouse United Kingdom is the PERT method better than GANNT or does which one you use depend on the type of project that you are delivering?
    2014-08-07 15:08:34

    • Yai Deng Yai South Sudan Both depend on each other.

    • Glen Holmes Ireland It isn't really a case of which one is better. In a lot of projects you would tend to use both. Gannt charts are great to see how much or what parts of the project are complete, on the other hand Pert diagrams are great to actively see the next stages of a project. Particularly when one part of a project cannot go ahead on till another is completed. Hope that helped.

  • Jones Hanungu Munang'andu Zambia Management Both during and after World War II the United States operated the largest and most advanced logistic system in the world. Its wartime operations stressed speed, volume, and risk-taking more than efficiency and economy. The postwar years, with accelerated technological change, skyrocketing costs, and diminished public interest in defense, brought a revulsion against military prodigality, manifested by calls for reduced defense budgets and a growing demand for more efficient management of the military establishment. This demand culminated in a thorough overhaul of the whole system in the 1960s. One result was the reorganization of logistic activities in the three military services, generally along functional lines, with large logistic commands operating under functional staff supervision. In each service, however, each major weapon system was centrally managed by a separate project officer, and central inventory control was maintained for large commodity groups. In 1961 a new defense supply agency was established to manage on a wholesale basis the procurement, storage, and distribution of common military supplies and the administration of certain common services. The most far-reaching managerial reforms of the period were instituted by the U.S. defense secretary, Robert S. McNamara (1961–68), in the resource allocation process. A unified defense planning–programming–budgeting system provided for five-year projections of force, manpower, and dollar requirements for all defense activities, classified into eight or nine major programs (such as strategic forces) that cut across the lines of traditional service responsibilities. The system was introduced in other federal departments after 1965, and elements of it were adopted by the British and other governments. In 1966 a program was inaugurated to integrate management accounting at the operating level with the programming–budgeting system. At the end of the 1960s a new administration restored some of the initiative in the planning–budgeting–programming cycle to the Joint Chiefs of Staff and the military services. The reforms of the 1960s exploited the whole range of current managerial methodology. The basic techniques, such as systems and operations analysis, all stressed precise, scientific, usually quantitative formulations of problems and mathematical approaches to rational decision making. Systems analysis, the technique associated with defense planning and programming, was a method of economic and mathematical analysis useful in dealing with complex problems of choice under conditions of uncertainty. The technological foundation of this improved logistic management was the high-speed electronic computer, which was being used chiefly in inventory control; in automated operations at depots, bases, and stations; in transmitting and processing supply data; in personnel administration; and in command-and-control networks.

  • Gregory Ngene Nigeria PERT DIAGRAM IS DIFFERENT FROM GANTT CHART. WHAT IS THE FULL MEANING OF GANTT AND PERT?
    2014-07-07 14:07:26

    • Yai Deng Yai South Sudan GANTT chart is the tool for management that was invented by Hentry GANTT to indicate activities, cost and timeframe for start and end meanwhile PERT is Performance Evaluation Review Technique that is used to show relationship between activities and time.
      2014-08-24 12:08:59
    • Marvin Banda Zambia GANTT charts they are better at identifying task and cost and PERT are better at identifying the activities and time frames

  • Philemon Johnson Liberia What is a GANTT chart and what do it does?
    2014-07-03 19:07:22

    • Yai Deng Yai South Sudan Just answered above.
      2014-08-24 12:08:36
    • Marvin Banda Zambia GANTT chart is a chart which displays tasks and costs along a horizontal time for each task, as well as indicating the start and the finish dates of the tasks. In short it shows the best possible way to complete the project in the shortest time

  • Asrat Zerihun Ethiopia Is a project manager must use both charts?
    2014-06-27 14:06:31

    • Yai Deng Yai South Sudan Yes.
      2014-08-24 12:08:11
    • Marvin Banda Zambia Yes GANTT displays tasks rather than the activities and time frames that PERT display
      2014-07-11 06:07:10
  • ODAFE PATRICK OHWOJERO Nigeria if a project manager has a PERT chart, why would he still need a GANTT chart
    2014-06-23 10:06:22

    • Yai Deng Yai South Sudan Because the two can be used together.
      2014-08-24 13:08:01
    • Marvin Banda Zambia PERT it shows all the activities and time frames whereas GANTT it shows each task when you started the project until you finish e.g PERT will look at the group of people working on the project as for GANTT will look at each task a person is working to finish the project
