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

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

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

As one determines requirements for a given system, it is necessary to define and allocate the appropriate design-to criteria for the different elements

True
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".

The management approach to identify, document, and audit the functional and physical characteristics of an item, and controlling changes to the item and its documentation is called Configuration Management. The purpose of this CM activity is to leave a complete audit trail of design decisions and the system modifications; typically, establish a baseline, then manage approval and documentation of all changes to the system
