Back to Status page contains 7 Questions 1) Evolutionary Acquisition (EA) is: [.101.1.1 Define the most common IT Acquisition Strategy approaches.] A way to explicitly solicit user feedback and allow for gradual refinement of user requirements over time as the system evolves. Another term used within the DoD for "Acquisition Lifecycle Management (ALM)." Characterized by acquisition, development and deployment of the total functional capability of the system in a single, sometimes very massive effort. A possible alternative approach specified for use by DoD acquisition policies to begin a major program when there is inadequate funding for the project. 2) A Single-Step (Grand Design) acquisition approach is being used for the new missile system. Single-Step (Grand Design) was most likely selected because: [2.101.1.2 Select the appropriate systems-level acquisition approach based on the characteristics of the system being developed.] The operational user, based on extensive prototype testing and evaluation, had firmly established a clear system specification calling for the use of existing, proven technology. Requirements are stable. The User was still uncertain about some critical requirements and cost estimates for implementing the remaining requirements, which varied widely. The only way the stated user requirements can be met is to develop a new system whose features have never been built before (unprecedented system). A variety of new state of the art technologies are required The user found a new technology that does everything they want. This technology has never been used before inside a missile system. However, the user thinks it will work for sure. 3) Match the model to the appropriate feature characteristic [2.101.1.3 Identify the proposed, system software-based, Evolutionary Acquisition model options defined by DoD.] a) Model 2: Defense Unique Software Intensive Program b) Model 3: Incrementally Fielded Software Intensive Program c) Model 5: Hybrid Program A (Hardware Dominant) d) Model 6: Hybrid Program B (Software Dominant) Used in the development of major weapons systems and features hardware development as the basic model structure combined with simultaneous software intensive development. Features a software intensive development that adds a mix of incrementally fielded software products or releases. Features planned software builds which should be logically structured to flow the workforce from effort to effort, while reducing overall cost and schedule program risk. Features the rapid delivery of capability through several limited fielding’s in lieu of single Milestones B and C and a single full deployment. 4) You are part of Program Management Office (PMO) IPT supporting the PM for a tactical communications system. One component of the project involves the acquisition of extremely lightweight and portable Commercial-off-the-shelf (COTS) computers that are rugged, low-power, waterproof, and that can support secure video satellite communications. Risks include that we really don't know specifically how light or how portable the gear needs to be, or if it will ultimately be affordable. Other operational requirements are in flux as well. However, all key interface requirements have been defined in great detail and are considered to be very stable. For this project, which of the following might be a good acquisition strategy? [2.101.1.4 Relate acquisition strategy approaches to risks.] We should use an Evolutionary Acquisition approach. Because of the unknowns, the PMO should attempt to defer development as long as possible, at least until the commercial market settles down. Because almost none of the requirements are very firm, a Single Step (Grand Design) approach would work best in this situation. Proceed with a Single Step (Grand Design) strategy based on the requirements that are firm now, and modify the program later as the rest of the requirements become stable and funding becomes more readily available. 5) An agile software development paradigm generally has all the following principles (pick the three that apply): [10.101.1.1 Define common software development paradigms.]  Requirements changes are welcome, even late in development.  The highest priority is to satisfy the customer through early and continuous delivery of valuable software. Software documentation is the primary measure of progress.  Deliver working software frequently. 6) Which of the following is NOT an important characteristic when selecting an effective software development method? [10.101.1.11 Match the software paradigm best suited for a given software item (SI) development.] [Remediation Accessed :N] The availability of a government software programmer Anticipated life span of the product Stability of technology base Availability of support contractors to provide continuity with the program office 7) Your project is using a Single Step (Grand Design) acquisition approach for the overall system, but the software developer has proposed using a Spiral Model paradigm for all of the software items comprising the system. Which of the following statements is most CORRECT? [10.101.1.12 Describe the relationship of software paradigms being proposed in the supplier's Software Development Plan (SDP) and the Acquisition Approach you should use for your program.] From an overall requirements risk assessment viewpoint, Single Step (Grand Design) is generally incompatible with Spiral Model software development. Single Step (Grand Design) means you evolve the system based on feedback, but in the Spiral Model, software must be totally completed to provide a stable design baseline. Single Step (Grand Design) is always used for software development when the requirements are uncertain. The developer made a good choice because DoD policy requires use of the Spiral Model for software development whenever a Single Step (Grand Design) approach is used.
