10. Analogous Estimating

    • Is when you look at activities from previous projects that were similar to this one and look at how long it took to do similar work before. But this only works if the activities and the project team are similar!

11. Three-Point Estimates

    • Are when you come up with three numbers: a most likely estimate that probably will happen, an optimistic one that represents the best-case scenario, and a pessimistic one that represents the worst-case scenario. The final estimate is the average.

12. Parametric Estimating

    • Means plugging data about your project into a formula, spreadsheet, database, or computer program that comes up with an estimate. The software or formula that you use for parametric estimating is built on a database of actual durations from past projects.

13. Reserve analysis

    • Means adding extra time to the schedule (called a contingency reserve or a buffer) to account for extra risk.

14. RBS

    • Create a hierarchical image that organizes the planned resources by their category and type (a resource breakdown structure)
