A quick and relatively […] The parametric technique uses such variables as duration (or cost) and the number of work packages / work units to develop estimates for upcoming projects.. [ Time Management ] Estimate Costs. What PERT does is manage probabilities. TheUS GAOdefines cost estimation as “the summation of individual cost elements, using established methods and valid data, to estimate the future costs of a program, based on what is known today.” The PMBOK defines the cost estimation process as “the process of developing an approximation of the cost of resources needed to complete project work.… After calculating E and V for each activity, add up the Es, and you have an accurate time estimate for project completion. It is not always advisable to use bottom-up estimating when you are short on time or resources. Linking dependent tasks is easy. Each task is a line on the Gantt chart, starting at one point and ending at the completion. You can even automatically calculate the critical path. Comparison Estimation. When comparing PERT Charts to Gantt Charts, on a Gantt chart, any dependent tasks—tasks that can’t start until another is finished—are linked. People often neglect to take historical data into their calculations and think only of what must be done, which makes estimations ill-informed. Project managers can factor in intuition, but it’s better to have backed up a schedule with hard data. Costs are estimated for the first time at the beginning of a project or even before a project has started.
