CVS CVS Function Analysis and FAST Diagrams Questions and Answers 2 — Questions and Answers
Question 1: What is the purpose of the Function-Cost-Worth matrix in VM?
- To assign team roles based on function complexity
- To compare what each function costs versus what it is worth to identify improvement targets (Correct answer)
- To schedule function analysis tasks during the workshop
- To document regulatory compliance requirements
Correct answer: To compare what each function costs versus what it is worth to identify improvement targets
The Function-Cost-Worth matrix highlights functions where cost exceeds worth, identifying the highest-priority areas for value improvement.
Question 2: In a verb-noun function statement, the verb should be:
- Passive (e.g., 'is supported')
- Active and measurable (e.g., 'transmit', 'reduce', 'protect') (Correct answer)
- An adjective describing quality
- A proper noun identifying a component
Correct answer: Active and measurable (e.g., 'transmit', 'reduce', 'protect')
Active, measurable verbs precisely describe the action performed, making functions clear and comparable across alternatives.
Question 3: When constructing a FAST diagram, the highest-order function on the left is typically called the:
- Supporting function
- Critical path function
- Higher-Order Function or 'Why' boundary (Correct answer)
- Cost driver function
Correct answer: Higher-Order Function or 'Why' boundary
The leftmost position in a FAST diagram represents the project's highest-order function — the ultimate 'why' or purpose that drives all other functions.
Question 4: The 'Required Functions Scope Line' in a FAST diagram marks:
- Functions that must be performed to meet user needs and basic requirements (Correct answer)
- Functions the team has creatively invented
- Functions eliminated during the Evaluation Phase
- Functions assigned to specific team members
Correct answer: Functions that must be performed to meet user needs and basic requirements
Functions within the required scope line are mandatory; those outside it represent design-specific choices that may offer value improvement opportunities.
Question 5: Which statement correctly identifies an 'unwanted function'?
- A function deliberately added for aesthetics
- A function that occurs as a negative side effect of performing other functions (Correct answer)
- A function required by the user but expensive to implement
- A function that supports the basic function indirectly
Correct answer: A function that occurs as a negative side effect of performing other functions
Unwanted functions are undesirable byproducts (e.g., 'generate heat' in an electrical system) that add cost without adding value.
Question 6: Why is function analysis considered the cornerstone of the VM process?
- It determines the project schedule and milestones
- It shifts focus from physical components to purpose, enabling broader creative solutions (Correct answer)
- It assigns financial accountability to team members
- It eliminates the need for stakeholder input
Correct answer: It shifts focus from physical components to purpose, enabling broader creative solutions
By focusing on functions rather than components, VM teams avoid design fixation and can explore a wider range of alternative solutions.
