Weight 3. Parametric estimating is a technique for estimating cost and duration. In this article, estimation tools, such as Analogous Estimating, Resource Cost Rates, and Bottom-up Estimating are explained. You collect three estimates based on the best case, most likely, and worst case scenarios. Time estimation using the Gantt chart is shown below, Top 10 cost estimation techniques in project management. The PMP exam might refer to this as a Beta Distribution or PERT (Program Evaluation and Review Technique) estimating. Final Thoughts.

The traditional approach is to estimate using a “bottom-up” technique: detail out all requirements and estimate each task to complete those requirements in hours/days, then use this data to develop the project schedule. You can’t do bottom-up estimating until you have a significant level of detail for the deliverables. These are used across many process groups, that are defined in PMBOK. Cost Estimation Tools. This is represented as an m for “most likely.” You might see this presented as cm for “cost most likely.”, Worst case (pessimistic): Assumes expensive resources, much rework, and delays in work getting accomplished. Parametric estimating is a statistics-based technique to calculate the expected amount of financial resources or time that is required to perform and complete a project, an activity or a portion of a project. Cost estimation is the process of forecasting the project’s cost with a defined scope. The simplest way is to use some kind of spreadsheet. This article on cost estimation techniques in project management (1) will help you remember the tools and techniques in the PMBOK guide for the estimate costs process and (2) can be used as a reference later when you are working on projects to estimate costs.
