In this guided project you will learn how estimate the durations of your project activities. You will estimate the duration of your project activities, using techniques such as Expert Judgment, Analogy, and Parametric Estimation. Once you have developed a WBS (see Guided Project: Creating a WBS, for how to create one), and decompose the work packages (lowest elements in the WBS) into the necessary activities (See Guided Project: Creating a Project Network Diagram), you can use the bottom up estimation technique. To improve the accuracy of your estimate you will learn how to use the three-point estimation technique, taking into account risk and uncertainty. You will also learn how use statistics to come up with an Interval Estimate with a up to a 99% confidence level. Note: This project works best for learners who are based in the North America region. We’re currently working on providing the same experience in other regions.
