Chapter 2

True

(True or False): During system operational use and life-cycle support, success data refers to information covering system operations and utilization on a continuing basis.

False

(True or False): Once the system is in production, it is not that important to maintain the system configuration and performance characteristics.

True

(True or False): Ranking of the customer needs in priority order is a part of the House of Quality (HOQ).

False

(True or False): Since system retirement and material disposal happen so far in the future, decisions made in design do not really have that much impact on that step in the System Engineering Process.

False

(True or False): The best way to test and evaluate a system is to first build the complete system and test the whole thing to see if it all works.

a) partitioning b) allocation c) traceability

Breaking the system down into subsystems and lower-level elements is called [a]. Dividing up the requirements into the various subsystems and major lower-level components is called [b]. There should be a [c] of requirements from top down and those identified at lower levels must directly support the requirements for the overall system.

FFBD stands for

a) Type 2 b) Type 4 c) Type 1 d) Type 3

Identify each of these 4 Testing Levels as Type 1, 2, 3, or 4: [a] Formal tests and demonstrations during later stages of detailed design and development phase; typically with preproduction prototypes; qualification type testing occurs here. [b] Formal tests conducted during system operational use and life-cycle support phase; typically at operational sites in real environment by operational and maintenance personal. [c] Evaluation of system components in the laboratory using engineering breadboards, bench test models, service test models, rapid prototyping; mainly to test functionality and performance in a development environment. [d] Formal tests at designated field sites by user personnel over an extended period of time; typically with early production or integrated models after system qualification and before completion of production/construction phase.

a) Organizational maintenance b) Intermediate maintenance c) Depot or supplier maintenance

Identify the 3 types or levels of Maintenance support for a system. [a] Performed at the operational site, typically by the using organization on its own equipment; typically includes periodic maintenance and simple repairs. [b] Performed by mobile, semi-mobile, and/or fixed specialized organizations and installations; typically includes removal and replacement of major modules and some system disassembly. [c] The highest level of maintenance and can do all levels of repair, system disassembly, module replacement, etc.; typically a fixed location and includes large inventory of spare parts and highly skilled specialists.
