  • Eugene Doris Nigeria A project plan is constructed within the planning phase. It contains all activities . These events are placed in a particular time sequence, ultimately producing something similar to a horizontal bar chart. Indication of slack time - events not on the critical path usually have slack time, extra time for that event that does not effect the timing of other events thus not effecting the project time. That means that can fall behind schedule and there is no impact on the project completion date

  • Eskalehu Abeje wubu Ethiopia Most projects come in late - that's just the way it is - so don't plan a timescale that is over-ambitious. Ideally plan for some slippage. If you have been given an fixed deadline, plan to meet it earlier, and work back from that earlier date. Build some slippage or leeway into each phase of the project. Err on the side of caution where you can. Projects which slip back and are delivered late, or which run over budget or fail to meet other financial requirements often cause significant problems. Many planners are put under pressure to deliver projects sooner and more cost-effectively than is realistic. Ambition and aiming high are good attitudes, but planning without proper prudence and responsibility is daft. Investors and executives tend rarely to question an over-ambitious plan, but they will quickly make very ruthless decisions when any overly ambitious project starts to fail. Exercising a little realism at the outset of a project regarding financials and timescales can save an enormous amount of trouble later.

  • Aggrey Kegome Kenya Historical data and personal experience should be the determinants when making activity time estimate.

  • Nothando Gumpo United Kingdom Good to be realistic when estimating time and consider each task separately

  • Shimmon Lezama Trinidad and Tobago I think this is critical because it is imperative that you don't underestimate the power of time.

  • Ralph Webster South Africa Each task has to be defined and the estimate of completion has to be made on the best available data to deliver a realistic time frame. Errors here can cause major changes in the project execution.

  • Sunday Sayepe Nigeria what are the risks involved in using historical data?
    2014-10-15 12:10:54

    • Siviwe Valtyn South Africa I wouldn't look at it from a risk factor, but rather a useful piece of information when available. Planning activity time duration requires all the info that one can get. So having historical data can't be a risk. However, one has to make sure that it is accurate historical data. So when recording that data one has to consider all the obstacles & challenges that had to be overcome to complete that activity.

  • Owan Manyo Ayuk Walters Cameroon Nice to know. Thanks Alison

  • Priya Deshmukh Other Time estimation may differs from the actual which may cause differences in output.

  • ANNETTE ROBINSON United States of America Wouldn't the historical data depend on your project and what's entailed?

  • Tesfaye Tessema Gintamo Ethiopia How can we estimate activity time in a normal conditions project management?

    • Yai Deng Yai South Sudan Is done through planning and consultation with stakeholders and experts.

  • Lukong Terence Cameroon Does each task in a project warrant a team task leader as regard respecting the activity timing ?????
    2014-08-21 10:08:36

  • Saw Minyau Germany Is there any effect if the project not in timing schedule?

    • Frank Alessio United States of America very seldom do projects run perfectly smoothly, there are many factors involved, to many variables to consider, purpose of charts and diagrams, power points are great but there is something that is never considered by management, which I like to call the x-factor. You can have 10,000 peices of paper drawing up one conclusion...the project will end on this date. It all looks spetacular on paper..and all it takes is that one security guard who wasnt feeling well..not to show up to work with the keys or the pass card...or that assistant that who after repeatedly was told to make sure that delievery of materials was sent on that day and they didnt make that call..... or the freight elevator person just got up on the wrong side of the bed that morning......

    • Yai Deng Yai South Sudan Yes the management of the project would not achieve the objective since there are timing for activities.
      2014-08-24 12:08:39
    • Tesfaye Tessema Gintamo Ethiopia Yes,because the project by itself time,budget and resources bounded so that without timing schedule the project ,, will encore high investment cost
      2014-08-21 19:08:26
    • ARIHO SIMPLISIO Uganda yes because it lead to bureaucracy
      2014-08-20 08:08:01
    • aula Al Helfe Iraq sure it will destroy the project cos you have time to hand over the project so any delay will make you loss money and your name
      2014-08-15 20:08:00
    • Asela Lauzon Philippines Yes, it greatly affects the project budget particularly if the client is budget conscious.
