Schedule Estimation is an indispensable activity performed on the project planning phase. By this activity we aim to give a maximally accurate appraisal to the project timeline. Schedule estimate is to be well-elaborated, realistic and feasible as it gives a ground for setting up expectations on a date of obtaining the project’s results and deliverables. These expectations (along with certain allowance of delay) are to be officially documented in the project’s contract and signed by its stakeholders as the project’s due date which the project performers should be committed to.
Inaccurate estimation can lead to violating of these timeframes, and this issue can entail penalties applied against the project’s performers. Schedule estimating is composed from putting in order and estimating durations of the smaller schedule elements, such as activities or tasks. In order to make a proper project schedule estimation you need to have a set of certain items at your hands (availability of all these items will maximize accuracy of estimate):
- Detailed outlook and a well-designed conception of work involved into the project;
- Work breakdown structure (WBS);
- Complete and systematized register of the actions to be done ;
- The Critical Path of the project ;
- Profound appraisal and opinions from concerned professionals and experts;
- Previous experience on similar type of work performed in the past;
- Assessment of risks which are forecasted to arise (for every task involved into the project);
- Capacity and productivity of equipment and manpower available to the project;
