Expert Judgement (Tools and Techniques): A brief paper describing work organizations utilizing their subject matter experts to properly address Estimate Activity Durations. PERT uses three-point estimating, a technique for Estimate Activity Duration processģ.
Three-point Estimating (Tools and Techniques): Homework problem from PMGT 613 involves determining the probability of finishing a project by a certain date. Organizational Process Assets (Input): an essay to explain estimate activity durations through historical data and lessons learned.Ģ. Once you have developed a WBS (see Guided Project: Creating a WBS. You will estimate the duration of your project activities, using techniques such as Expert Judgment, Analogy, and Parametric Estimation. In this guided project you will learn how estimate the durations of your project activities. Copyright 2013 by PMI.Inc, Reprinted without permission.ġ. Project Scheduling: Estimate Activity Durations.
Reprinted from "A Guide to the Project Management Body of Knowledge (PMBOK) 5th ed" by Project Management Institute, 2013, p.166. The duration can be estimated more accurately once deliverables become more understood.Įstimate Activity Durations: Inputs, Tools and Techniques, and Outputs. Labor and the time it takes can to complete can be difficult to estimate if and when constraints develop through the project life cycle. In this technique, Estimating the basis for activity duration. In my experience, building the schedule and working out the activity estimates are two processes that overlap majorly. These feed into the next process, where you create a project schedule. This process can be somewhat ambiguous considering there are moving parts. There are number of techniques for determining durations and one is Parametric Estimating. Next it’s time to work out the overall duration of the project based on the duration of the individual tasks. It is more accurate to assign activity duration until all resources have been assigned.
If not able to accurately estimate the duration of an activity, decompose activity. During the project, resources may not be as readily available. Tool of Estimate Activity Duration Process.
