  • Md Shohel Mahmud Bangladesh Previous data could be a help but it is very crucial to think each task separately and in a practical way.

  • Sánjìv Shakya Nepal A project must be divided multiple assignment as per the requirement and as per the available manpower. Each assignment should estimate a certain time duration as per past records.

  • Franklin King Liberia A project manager must always be cautious about project time frame considering the PERT which provides clear picture about the task to be implemented and the timing

  • Lesley McLaughlin United States of America If first (or second) hand experience and historical records are not available, is there a "best" way to estimate activity time?

    • Amadeu Alexandre Angola Hi Lesley, If it's the first project to be managed you can contact experts i mean other people with a good experience in project management and contact people who did the same work to help you estimate the duration of the project

    • Ize Adava United States of America Not sure there is a 'best' way, it would mostly have to be discretionary, with room for adjustments.

  • 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

    • Lesley McLaughlin United States of America This is true, but what if some resource, like personnel, from the activity or task will be required for another activity or task on the time line. I would be cautious when counting on "slack."

  • 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.
