SENG 312 EXAM 1 | QUESTIONS AND ANSWERS | 2026 UPDATE | WITH COMPLETE
SOLUTION
System - (ANSWER)A set of interacting or interdependent component parts forming a complex or
intricate whole.
Systems Thinking - (ANSWER)Is the use of various techniques to study and understand systems of many
kinds.
Defining a System - (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 - (ANSWER)Represents an element of a system that may contribute a system itself.
Safety - (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 - (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 - (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 - (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 - (ANSWER)-Concept Definition

SOLUTION
-Development (Preliminary design, detailed design, test)
-Production
-Operation
-Disposal
Core System Safety Process Steps - (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 - (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 - (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 - (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 - (ANSWER)Hazard; peril; jeopardy. An expression of the impact and possibility of a mishap on
terms of potential mishap severity and probability of occurrence.
Swiss Cheese Model - (ANSWER)Systems approach to understanding errors. Declares humans are fallible
and errors are to be expected even in the best organization. The holes represent opportunities for the
process to fail
