price for their customer’s project. In order to pick the best answer, you need to realize that analogous estimating is a form of expert … of advantages and disadvantages. Subsequently, they are using the observed cost and Marketing Analogous estimating is generally less costly than other techniques, but it is also generally less accurate. of estimates (e.g. What Is the Difference between Parametric and Analogous resource requirements in the early stages of a project and to determine to produce more accurate results thanks to its statistical and data-driven According to the Standish Group CHAOS report of 2003: 1. in an early planning stage. Parametric estimating, a more accurate technique for estimating cost and duration, uses the relationship between variables to calculate the cost or duration. technique which uses the values of parameters from historical data as the basis for estimating similar parameter for a future activity A. project A. higher cost and take 20% more time than Project A, their estimates would be: For some projects, a breakdown into the breakdown (ratio estimate) to check the availability of resources, e.g. schedule or resources, the analogous estimation technique comes with a number analogous estimates are particularly common in the project selection or The team applies some expert judgment and While it is less accurate than other methods, it can be used to produce an order of magnitude or an initial estimate. Both estimating techniques can be used to determine both project cost and project durations. more accurate figures over the course of a project. It involves leveraging the estimators’ Introduction . Reserve analysis.

Q7. manager or the team to come up with three different estimates: These values are then transformed into a final estimate using the triangular or the PERT distribution. including inflation, etc.) A. earned value. Analogous Estimation. Such expertise may be provided by any group or person with specialized education, knowledge, skill, experience, or training. 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 top-down estimating method. indicators of past projects in a dedicated database. 6.4.2, 7.2.2, 9.2.2). Last year it took one week to design the on-line registration form and the cost to host the registration website was $850.00 You estimate the same this year. Because the project manager’s, and possibly the team’s, experience and judgment are applied to the estimating process, it is considered a combination of historical information and expert judgment. Analogous estimating is typically a form of expert judgment that is most reliable when the previous activities are similar to the current activity and when the team members preparing the estimates have the necessary experience. B. The technique is simple and time taken for estimation is very less. 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. particularly common to estimate entire projects or larger portions of a project amount to 25% of the total cost of an IT project, for instance. All in all, parametric estimating tends to Cost: $700 (parametric estimating 4 x $25 x 7) Cost Estimating Rationale, Expert Judgement, Analogy based cost estimating, Cost Estimating Knowledge, Inference Modelling. 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. be customized. respectively. come up with a ‘most likely’ estimate. These numbers can help obtain a decision of whether the B. estimates. A ratio estimate describes the relative It is however often accompanied Analogous estimating is the act of using former projects to estimate how long or how much a current project will take or cost. In this article, the use of Expert Judgement (EJ) is examined with respect to generating cost estimates. Estimates tend to be rough and less significant parts of a project could also be estimated using this method. Two estimating techniques that may appear on the PMP, CAPM, PMI-SP, and PMI-RMP exams are analogous estimating and parametric estimating. 1. ____________ is another term for top down estimating. Analogous estimating is a technique for estimating the duration, resources or cost of an activity or a project using historical data from a similar activity or project. One can go for this method if they have some comparable data and time to make the estimates. Getting the historical cost, durations and/or resource requirements and additional details on the characteristics of past projects, e.g. concludes that the characteristics of the current project are similar to Therefore, time estimates for an activity or a project must be in a range. This feedback can then be used to produce more accurate Agree to analogous estimating. A company must consult individuals or groups that are experts in the field in which the company operates, or the project focuses on. 2-EXPERT JUDGEMENT. Suggest life cycle costing as a compromise. Analogous estimating, on the other hand, This is the longest method to complete, but it provides the most accurate estimate. Analogous Estimating. Designed to help those that are preparing to take the PMP or CAPM Certification Exam, each post within this series presents a comparison of common concepts that appear on the PMP and CAPM exams. Correct Answer: B An analogous estimate is a form of expert judgment because it relies on historical information. If you enjoyed reading this post, check out all of our post on PMP Concepts Learning Series. Estimators might expect, that historical data or experience of the estimators would be applicable to the This only works if you analyze the same kind of projects, but if you don’t have previous data, this technique is not applicable. The cost estimate is based on historical data from similar projects. Estimating? Inserting the Question: 1. Most reliable when: Activities are really similar. types of analogous estimating can be used in practice. You will find an overview of the different methods in this article on cost estimation and this article on duration estimation. A. This means that the more data that is available, the better the estimate will be. C. Determine why the sponsor wants such an accurate estimate. Analogous Estimating Is A Form Of _____Expert JudgmentBottom Up EstimatingDelphi MethodComputerized Estimating 2. approach. the time for producing 1000 component based on that for 1 component * 1000, use an algorithm based on historical data, accuracy … analogous estimating in project management. However, it is In any case, the team will probably share the Two projects have exactly the same payback period but project A has a smaller IRR than project B. D. parametric modelling. Question 41 ELSEVIER INFORMATION AMD SOFTWARE TECHNOLOGY Information and Software Technology 38 (1996) 67-75 Expert judgement as an estimating method Robert T. Hughes Department of Computing, University of Brighton, Moulsecoomb, Brighton BN2 4GJ, UK Abstract This paper reviews some past research that may be relevant to the way that 'expert judgement' is used to produce … experience, project efforts and time are usually distributed as follows: Applied to their previous estimate, their Analogous estimating is a form of _________ Expert Judgment Bottom up estimating Delphi method Computerized estimating 2. B. Such expertise may be provided by any group or person with specialized education, knowledge, skill, experience, or training. C. Try to convince the sponsor to allow expert judgment because it is typically more accurate. application of historical data or experience to a current project. There will be four people used to coordinate the race. A technique where an estimate for each component in the WBS is developed and then totaled for an overall project budget. scope, activities, complexity, environmental factors, etc. Analogous estimating is a common technique in project management to determine cost, schedule or resource estimates. Essentially, a parametric estimate is determined by identifying the unit cost or duration and the number of units required for the project or activity. not many details about the Expert Judgment is a technique in which judgment is provided based upon a specific set of criteria and/or expertise that has been acquired in a specific knowledge area, application area, or product area, a particular discipline, an industry, etc. In other words, it is a technique that centers on comparison. on analogous estimating mainly in situations where only limited resources or Project Estimating), or in the early stages of a project. Analogous Estimating: the estimation is made by simply taking the values from past projects/activities with similar scope to the current projects/activities (somewhat like making an analogy) 1. the fastest and easiest estimation method to give a rough estimation 2. requires a combination of historical information and expert judgment (the information from past projects can be adjusted with consideration of the special circumstances of the current project, e.g. Suggest life cyde costing as a compromise C. Determine why the sponsor wants such an accurate estimate D. Try to convince the sponsor to allow expert judgment because it is typically more accurate Answer:-A. Introduction . Each resource will be paid $25 per hour and they will be working an estimated seven hours, based on the race last year. The historical information, assuming that it is accurate, serves as the conduit to the expert that created the historical information.
