Equipment Design Review Software Design Review Critical Design Review

The purpose of a design review process is to

Evaluate the system configuration at different stages in terms of the requirements

Type 1 Testing

Evaluation of system components in the laboratory using engineering breadboards, bench test models, service test models, rapid prototyping

CAD, CAM, and CAS are totally separate tool sets and there is little chance that there is smooth and automated flow of information from any one or another

False

It is not important to address the interaction effects between the newly designed system and other systems that operate independently within geographical area

False

Once the system is in production, it is not important to maintain the system configuration and performance characteristics

False

SE typically leads the planning and control aspects

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

False

System engineers are usually responsible for the project management for the entire system development program

False

Constructing a three-dimensional scale model of the system, or an element thereof, is called a physical rapid proto-type

False, Mock-up

Type 2 Testing

Formal tests and demonstrations accomplished during the latter stages of the detail design and development phase when preproduction prototype equipment and software are available

What step of the SE process does the text ask "Why must these functions be accomplished?"

System Requirements (Needs Analysis)

Functional Baseline

System becomes functional and configuration must be documented

A significant management challenge for SE is to evaluate and integrate the CAD tools for a system project, where they work together

At some point, the systems development team "freezes" the design. This "frozen" design becomes the reference design and any changes must go through managed and disciplined change control and is called the "baseline".
