Agree to analogous estimating, as it is a form of expert judgment B. Analogous Estimation. You are the project manager for the annual Earth Day 5k road race, with three primary components: marketing, registration, and race-day coordination. The measurement must be scalable in order to be accurate. B. project B. C. there is no difference. Like any other approach to estimating cost, previous project. customer to estimate the implementation cost of off-the-shelf software. Agree to analogous estimating, as it is a form of expert judgment. D. parametric modelling. What Are the Typical Uses of Analogous Estimating in analogous estimation technique are applied to the following situation: An IT vendor is asked by a prospective statistical evidence of assumed relationships. D. parametric modelling. experience or historical data from previous projects by adopting observed cost, use for decision-making or project planning and controlling. Analogous estimates are used by project Another use is the estimation of a The cost estimate is based on historical data from similar projects. system physical or performance last edited by: Keith Emery on Apr 7, 2017 7:10 PM: login/register to edit this page: Keywords: Estimating: Contents 1 Overview 2 Application 3 Visual representation, Example 4 Other Estimating Techniques 5 References : Overview . You want a form of expert judgment, but the sponsor argues for analogous estimating. project (and/or comparable projects) are known, or. A. This technique is combined with expert judgement to determine if the two activities are truly alike. Analogous estimating is typically a form of expert judgment that is most reliable not only when the previous activities are similar to the current activity in fact, and not just in appearance, and also is traditionally most effective when the team members preparing the estimates have the expertise necessary to accurately do so. Analogous estimating is a form of expert judgment. 1) Expert Judgement Method Expertise should be considered from individuals or groups with specialized knowledge or training in team and physical resource planning and estimating. If you enjoyed reading this post, check out all of our post on PMP Concepts Learning Series. Analogous Estimating Is A Form Of _____Expert JudgmentBottom Up EstimatingDelphi MethodComputerized Estimating 2. While it is less accurate than other methods, it can be used to produce an order of magnitude or an initial estimate. price for their customer’s project. However, analogous estimates are less accurate than other forms of estimating, as they are prepared with a limited amount of detailed information. • Three-Point Estimates: It is important to understand that statistically there is a very small probability of completing a project on any one date. Estimating? It would be BEST to: A-) Agree to analogous estimating, as it is a form of expert judgment . they are often not very accurate. In order to pick the best answer, you need to realize that analogous estimating is a form of expert … activities. with cost, duration or resource-related values of a project. As a project manager one of the most important thoughts at project start-up is the reliability of the estimates. Explain each of the following estimating techniques, and how each can be used to determine task duration and resource effort. Therefore, it is a common technique during the selection or initiation of projects. or the ratio estimates. It requires calculations and Determine why the sponsor wants such an accurate estimate. You use this technique when limited project … exact match in their historical data, they tend to prefer estimating a range that historical data or experience of the estimators would be applicable to the Save my name, email, and website in this browser for the next time I comment. Therefore, time estimates for an activity or a project must be in a range. parameters of the current project will then lead to the estimates for the []. Answer is A. This type of estimating can be performed with very limited available data. Parametric Estimating. Agree to analogous estimating, as it is a form of expert judgment. It can then be used in program management or for early, An analogous estimate is often an initial estimate for a project or parts of a project at a time when not much information is available. Analogous estimating is typically a form of expert judgment that is most reliable not only when the previous activities are similar to the current activity in fact, and not just in appearance, and also is traditionally most effective when the team members preparing the estimates have the expertise necessary to accurately do so. requires a similar budget, the analogous estimate would be $100,000, an One form is estimating •Analogous Estimating: Analogous estimating is a form of expert judgment. c. Has an accuracy rate of ±10% of actual costs. Duration: one week (analogous), Coordination In practice, top-down estimates This is the longest method to complete, but it provides the most accurate estimate. Parametric Cost Estimating2 Parametric cost estimates are a result of a cost estimating methodology using statistical relationships between historical costs and other program variables (e.g. estimate, the estimators compare the characteristics of the upcoming project It would be BEST to: A. Q9. C. Determine why the sponsor wants such an accurate estimate. range (cost of 100 to 200 and a duration of 40 to 70 days) as an order of It involves identifying parameters in historical data that correlate manishpn Expert … This explanation cleared up the mud for me. Analogous Estimating. Very nice explanation with examples. Parametric Estimating Parametric estimating is used if you do not have detailed information on which to base time estimates. Estimation Methods. Agree to analogous estimating, as it is a form of expert judgment Expert judgment is a recognized, mature research methodology. D. Try to convince the sponsor to allow expert judgment because it is typically more accurate. time, such estimates are usually refined or replaced based on more accurate types Life cycle costing Parametric modeling Analogous estimating Work package 3. Both estimating techniques can be used to determine both project cost and project durations. Suggest life cycle costing as a compromise. 1. Correct Answer: B An analogous estimate is a form of expert judgment because it relies on historical information. Project Estimating): For the high-level management of a portfolio of projects, different parts of a project may be required. B. Three Point Estimates. Creating a list of similar projects (you can start with a longlist first and refine it later). be customized. Analogous Estimating Is A Form Of _____Expert JudgmentBottom Up EstimatingDelphi MethodComputerized Estimating 2. Expert Judgment Estimating: Expert Judgment is a term that refers a specifically to a technique in which judgment is made based upon a specific set of criteria and/or expertise that has been acquired in a specific knowledge area, or product area, a particular discipline, an industry, etc indicators of past projects in a dedicated database. Analogous Estimating. Expert Judgment can be provided by a member or … Advantages and Disadvantages of Analogous Estimating. The team then uses the above-mentioned Expert judgement (in project management) is whenever the project manager consults with professionals, who happen to be experts on a subject, to get their opinion about that specific subject. For instance, if they expected the current project to incur 30% 6.4.2, 7.2.2, 9.2.2).While it is less accurate than other methods, it can be used to produce an order of magnitude or an initial estimate.
