Document Content and Description Below

1) True or False. One of the reasons that accurate project estimates are needed is that estimates are used to assess the impact of changes and permit re-planning. [15.101.1.1 Describe why accurate e... stimates are needed.] False True 2) has the most important impact on cost and schedule estimates. (Fill in the blank.) [15.101.1.2 Identify key estimation "Lessons Learned."] Software size Developer experience level Type of programming language being used Choice of software development paradigm 3) The estimating technique is the most accurate technique for estimating system production costs, but is not particularly useful for initial software estimating. (Fill in the blank.) [15.101.1.3 Recognize methods best suited for different software estimation situations.] Actual Cost Analogy Expert Judgment (Delphi Method) Bottom-Up 4) Select the BEST answer. Which of the following is a cost driver that can influence a developer's software cost and schedule estimates? [6.101.1.1 List factors that most influence software cost and schedule estimates.] Schedule and staffing constraints. If the Government Program Management Office (PMO) is adequately staffed. Whether or not a software measurement program is being employed. The level of Earned Value Management used. 5) Which common cost and schedule estimating method is used when teams of experts first independently make a resource estimate and then meet to reach consensus on an overall estimate? [6.101.1.2 Describe common cost and schedule estimation methods.] [Remediation Accessed :N] Expert Judgment Top-down Estimating Bottom-Up Estimating Parametric Methods 6) Which THREE of the following are ways that software parametric cost estimation models typically work? Select three. [6.101.1.3 Describe the attributes of parametric models.] Input parameters are related to common cost and schedule drivers. Parameters are used as inputs and are designed to be tailored and "calibrated." Various mathematical models of the development process are used. Software "size" is rarely used in a software cost model. [Show More]
