Which methods are used to convert operational RAM requirements into contractual RAM requirements? (Select the five alternatives that apply.) - ANSWER 1.**** Apply a formal translator. 2.**** Apply a systems engineering approach. 3.*** Apply a policy. 4.**** Apply cost, schedule, or other constraints 5.***** Ask industry what is the best that can be done. Why might field reliability data differ from contractual reliability data? (Select the three alternatives that apply.) - ANSWER 1.**** The user changes the mission. 2. **** Field removals that were counted as failures are later determined to have no-defects. 3.*** Failures can be caused by interacting components and have been incorrectly classified as failures, rather than removals. What is a common reason why Mean Time Between Failure (MTBF) and Mean Time Between Maintenance (MTBM) are confused by both program offices and users in the field? - ANSWER Lack of understanding of the meaning of the term. Which of the following is an example of a nondevelopmental item? - ANSWER Item developed for and in-use by the government. When conducting market investigation, which of the following RAM-related questions should you ask? Select the two options that apply. - ANSWER 1.***** What is the MTBF and how are time and failure defined? 2.**** What RAM processes were conducted as part of the design and development of the item? Which of the following are reasons why field reliability data may differ from contractual reliability data? (Select the three alternatives that apply.) - ANSWER 1.**** The user changes the mission. 2.**** Field removals that were counted as failures are later determined to have been no-defect removals. 3.**** Failures are caused by interacting components. Which method of converting operational reliability, availability, and maintainability (RAM) requirements to contractual RAM requirements provides numbers that may drive up costs or may not be technically feasible? - ANSWER Apply of a policy. Which of the following describes an acceptable method for converting operational reliability, availability, and maintainability (RAM) requirements to contractual RAM requirements? - ANSWER Use of the Mean Time Between Failure (MTBF) translator of three times the Capability Development Document (CDD) threshold value of Mean Time Between Maintenance (MTBM). Which of the following describes a commercial item? - ANSWER An item available "Off the Shelf" or through a catalog. A previously developed item of supply used exclusively for governmental purposes is what type of item? - ANSWER Nondevelopmental Item (NDI).
