SENG 312 EXAM 1 QUESTIONS AND ANSWERS
System - CORRECT ANSWER✅✅A set of interacting or interdependent component parts forming a
complex or intricate whole.
Systems Thinking - CORRECT ANSWER✅✅Is the use of various techniques to study and understand
systems of many kinds.
Defining a System - CORRECT ANSWER✅✅-Composed of parts.
-A system is greater than the sum of its parts.
-All parts of a system must be related.
-Has a boundary.
-Can be nested inside another system.
-Is autonomous in fulfilling its purpose (a car is not a system. A car with a driver is a system).
Subsystem - CORRECT ANSWER✅✅Represents an element of a system that may contribute a system
itself.
Safety - CORRECT ANSWER✅✅A measure of the degree of freedom from risk or conditions that can
cause death, physical harm, or equipment or property damage. Should be thought of as a characteristic
of a system like quality, dependability, or reliability.
Safety System - CORRECT ANSWER✅✅A design that works automatically to prevent accidents; a system
that reduces possible hazards due to human error (i.e. system shutdown).
System Safety - CORRECT ANSWER✅✅The application of engineering and management principles,
criteria, and techniques to optimize all aspects of safety within the constraints of operational
effectiveness, time, and cost throughout all phases of the system life cycle (must consider system as a
whole).
Systems Engineering - CORRECT ANSWER✅✅Is an interdisciplinary field of engineering focusing on how
complex engineering projects should be designed and managed over their life cycles.
, System Life Cycle - CORRECT ANSWER✅✅-Concept Definition
-Development (Preliminary design, detailed design, test)
-Production
-Operation
-Disposal
Core System Safety Process Steps - CORRECT ANSWER✅✅1. Safety plan/define system
2. Identify hazards
3. Assess hazard risk
4. Identity safety measures
5. Reduce risk
6. Verify risk reduction
7. Review hazards and risk
8. Track hazards
Hazard - CORRECT ANSWER✅✅To risk; to put in danger of loss or injury. Any real or potential condition
that can cause injury, illness, or death to personnel; damage to or loss of a system, equipment or
property; or damage to the environment.
Accident - CORRECT ANSWER✅✅An undesirable and unexpected event; a mishap; an unfortunate
chance or event that results in damage to property, material, equipment, or cargo, or personal injury or
death.
Mishap - CORRECT ANSWER✅✅An unfortunate accident. An unplanned event or series of events
resulting in death, injury, occupational illness, damage to or loss of equipment or property, or damage
to the environment.
Risk - CORRECT ANSWER✅✅Hazard; peril; jeopardy. An expression of the impact and possibility of a
mishap on terms of potential mishap severity and probability of occurrence.
