Value Methodology Associate Questions and Answers
An unwanted function of a hammer would be:
Options:
Swing arm
Apply force
Deliver force
Transmit vibration
Answer:
DExplanation:
Function Analysis in Value Methodology involves identifying and classifying functions of a product, process, or system using verb-noun combinations, as taught in the VMF 1 course (Core Competency #2). Functions are categorized as basic (essential to the purpose), secondary (supporting), or unwanted (undesirable outcomes). For a hammer, the basic function is to “deliver force” to drive a nail, while secondary functions like “swing arm” or “apply force” support this purpose. An unwanted function is an unintended or negative outcome of the hammer’s use.
Option A (Swing arm) is a supporting function, describing the action of the user’s arm to generate momentum, and is not unwanted.
Option B (Apply force) is a secondary function, as it describes the action leading to delivering force, and is not unwanted.
Option C (Deliver force) is the basic function of a hammer, essential to its purpose, and not unwanted.
Option D (Transmit vibration) is correct because it represents an unintended and undesirable outcome—vibration transmitted to the user’s hand can cause discomfort or fatigue, making it an unwanted function.
The VMF 1 course emphasizes identifying unwanted functions to target areas for value improvement, such as redesigning the hammer to reduce vibration.
Functions on a FAST diagram's function logic path follow:
Options:
When-Why logic
How-Why logic
How-When logic
And-Or logic
Answer:
BExplanation:
The Function Analysis System Technique (FAST) diagram is a key tool in Value Methodology’s Function Analysis phase, as taught in the VMF 1 course (Core Competency #2). The function logic path in a FAST diagram is the horizontal sequence of functions, often referred to as the critical path (as identified in Question 3 with arrow Y). According to SAVE International’s Value Methodology Standard, “the function logic path in a FAST diagram follows a How-Why logic: moving to the right answers ‘how’ a function is performed, and moving to the left answers ‘why’ a function exists.” This logic helps trace the relationships between functions, starting from the higher-order function (e.g., Function E, as noted in Question 18) on the left to more specific functions on the right (e.g., Function O).
How: Moving right along the path (e.g., from E to F to G) explains how the preceding function is achieved.
Why: Moving left (e.g., from O to N to M) explains why the succeeding function is needed.
In the diagram, the critical path (E-F-G-J-L-M-N-O) follows this How-Why logic, as confirmed in earlier questions (e.g., Question 3). The “when” direction (vertical, as noted in Question 36) and “and-or” logic (used at junctions for concurrent or alternative functions) are not the primary logic of the function logic path.
Option A (When-Why logic) is incorrect because the “when” direction is vertical, indicating simultaneous functions, not the horizontal logic path.
Option B (How-Why logic) is correct, as it matches the standard logic of the function logic path in a FAST diagram.
Option C (How-When logic) is incorrect because the “when” direction does not apply to the horizontal logic path.
Option D (And-Or logic) is incorrect because “and-or” logic applies to junctions (e.g., gates for concurrent or alternative functions), not the main logic path.
Which of the three levels of filters used for evaluating ideas during the Evaluation Phase applies an evaluation matrix technique?
Options:
Fine
Reasonable
Medium
Coarse
Answer:
AExplanation:
The Evaluation Phase of the Value Methodology (VM) Job Plan involves assessing ideas using a three-level filtering process, as taught in the VMF 1 course (Core Competency #7: Evaluation and Selection of Alternatives). According to SAVE International’s Value Methodology Standard, the three levels of filters are Coarse, Medium, and Fine (as confirmed in Question 33). The standard further specifies that “the Fine filter applies detailed evaluation techniques, such as an evaluation matrix, to select the best ideas for development by scoring them against weighted criteria.” An evaluation matrix (e.g., a weighted matrix, as noted in Question 11) is a tool where ideas are scored based on criteria like cost, performance, and risk, with weights reflecting their importance (as in Question 51). This detailed, quantitative approach is used in the Fine filter to make final selections after the Coarse (initial screening) and Medium (shortlisting) filters have narrowed down the ideas.
Option A (Fine) is correct, as the Fine filter uses an evaluation matrix technique for detailed idea selection.
Option B (Reasonable) is incorrect because “Reasonable” is not one of the three filter levels; the correct levels are Coarse, Medium, and Fine.
Option C (Medium) is incorrect because the Medium filter involves a more general assessment (e.g., comparing ideas against criteria), not the detailed matrix technique.
Option D (Coarse) is incorrect because the Coarse filter is for initial screening (eliminating unfeasible ideas), not detailed evaluation with a matrix.
In which phase is a large quantity of ideas or alternatives generated to accomplish the functions?
Options:
Creativity Phase
Presentation Phase
Evaluation Phase
Function Analysis Phase
Answer:
AExplanation:
The Value Methodology (VM) Job Plan consists of six phases, as outlined in the VMF 1 course (Core Competency #3: Value Methodology Job Plan). The phase dedicated to generating a large quantity of ideas or alternatives is the Creativity Phase (also known as the Creative Phase). According to SAVE International’s Value Methodology Standard, “the Creativity Phase is where a large quantity of ideas or alternatives is generated to accomplish the functions identified in the Function Analysis Phase, using techniques like brainstorming to encourage divergent thinking.” This phase focuses on producing as many ideas as possible without judgment, as established in Question 40, where the objective of the Creativity Phase was confirmed as generating improvement ideas.
Option A (Creativity Phase) is correct, as it is the phase dedicated to generating a large quantity of ideas to accomplish functions.
Option B (Presentation Phase) is incorrect because this phase involves presenting recommendations to stakeholders, not generating ideas.
Option C (Evaluation Phase) is incorrect because this phase involves assessing and selecting ideas, not generating them (as noted in Question 33).
Option D (Function Analysis Phase) is incorrect because this phase focuses on identifying and analyzing functions, not generating ideas (as noted in Question 37).
Which of the following defines the effects of time, value, and money, converting all costs to a common reference point in today's dollars?
Options:
Return on Investment (ROI)
Present Worth (or Net Present Value)
Discount Rate
Simple Payback (or Breakeven Point)
Answer:
BExplanation:
In Value Methodology, cost analysis often involves evaluating the economic impact of alternatives over time, which requires understanding the time value of money. The VMF 1 course, under Core Competency #4 (Cost Analysis), includes financial concepts like discounting cash flows to assess long-term value. The concept of converting all costs to a common reference point in today’s dollars refers toPresent Worth (or Net Present Value, NPV). According to SAVE International’s Value Methodology Standard, Present Worth (or NPV) is used to “evaluate the economic feasibility of alternatives by discounting future cash flows to their present value, accounting for the time value of money.” This process converts all costs and benefits (adjusted for time, value, and money) to a single value in today’s dollars using a discount rate, allowing for a fair comparison of alternatives.
Option A (Return on Investment or ROI) is incorrect because ROI measures profitability as a percentage and does not convert costs to a present value.
Option B (Present Worth or Net Present Value) is correct because NPV accounts for the effects of time, value, and money by discounting future cash flows to today’s dollars.
Option C (Discount Rate) is incorrect because the discount rate is the rate used in NPV calculations, not the method of converting costs itself.
Option D (Simple Payback or Breakeven Point) is incorrect because payback measures the time to recover an investment and does not account for the time value of money or convert costs to present value.

In SWOT analysis:
Options:
Strengths and opportunities are internal attributes.
Threats and strengths are harmful attributes.
Strengths and weaknesses are helpful attributes.
Opportunities and threats are external attributes.
Answer:
DExplanation:
SWOT analysis (Strengths, Weaknesses, Opportunities, Threats) is a tool sometimes used in Value Methodology, particularly during the Information Phase or Evaluation Phase, to assess the context of a project or product, as taught in the VMF 1 course (Core Competency #3: Value Methodology Job Plan). According to SAVE International’s Value Methodology Standard, “SWOT analysis evaluates internal and external factors: Strengths and Weaknesses are internal attributes of the system or organization, while Opportunities and Threats are external attributes from the environment.”
Strengths: Internal, helpful attributes (e.g., strong design team).
Weaknesses: Internal, harmful attributes (e.g., high production costs).
Opportunities: External, helpful attributes (e.g., market demand).
Threats: External, harmful attributes (e.g., regulatory changes).
This framework helps the VM team identify factors that could impact the study’s success, such as external opportunities to leverage or threats to mitigate.
Option A (Strengths and opportunities are internal attributes) is incorrect because opportunities are external, not internal.
Option B (Threats and strengths are harmful attributes) is incorrect because strengths are helpful, not harmful.
Option C (Strengths and weaknesses are helpful attributes) is incorrect because weaknesses are harmful, not helpful.
Option D (Opportunities and threats are external attributes) is correct, as both are external factors in SWOT analysis.
The Value Methodology is:
Options:
A suggestion program to improve value.
A cost reduction exercise to improve value.
A step-by-step design review to improve value.
An eight-phase process to improve value.
Answer:
CExplanation:
Value Methodology (VM), as defined by SAVE International in the Value Methodology Fundamentals 1 (VMF 1) course, is a systematic, step-by-step approach to improve the value of a project, product, or process by optimizing the function-to-cost ratio. According to SAVE International’s Value Methodology Standard, VM is described as “a systematic and structured approach for improving projects, products, and processes… to achieve the optimum balance between function, performance, quality, safety, and cost.” The VM Job Plan, a core component of VM, involves a step-by-step process (six phases: Information, Function Analysis, Creative, Evaluation, Development, and Presentation) that can be likened to a design review because it evaluates and enhances the design or process to improve value.
Option A (suggestion program) is incorrect because VM is not merely about collecting suggestions; it is a structured methodology with defined phases and tools like function analysis.
Option B (cost reduction exercise) is incorrect because VM focuses on improving value, not just reducing costs—cost reduction may occur, but only if it does not compromise essential functions.
Option C (step-by-step design review) aligns with VM’s systematic nature, as the Job Plan reviews and improves designs or processes through structured phases, making it the best fit.
Option D (eight-phase process) is incorrect because the VM Job Plan has six phases, not eight, as established in SAVE International’s standards.
Which of the following is the risk response strategy for opportunities that seek to increase the probability of an opportunity occurring and/or the magnitude of results being beneficial?
Options:
Exploit
Share
Mitigate
Enhance
Answer:
DExplanation:
Risk management in Value Methodology (VM) includes strategies for both threats and opportunities, particularly during the Implementation Planning phase, as taught in the VMF 1 course (Core Competency #8: Implementation Planning). According to SAVE International’s Value Methodology Standard, which aligns with project management best practices (e.g., PMI’s PMBOK, as noted in Question 28), risk response strategies for opportunities include:
Exploit: Ensure the opportunity is realized by taking actions to make it certain (e.g., assigning the best resources).
Share: Partner with others to increase the likelihood or benefit of the opportunity (e.g., joint ventures).
Enhance: Increase the probability of the opportunity occurring and/or the magnitude of its beneficial results (e.g., by improving conditions or amplifying benefits).
Accept: Take no action to influence the opportunity.
The question specifically asks for the strategy that seeks to “increase the probability of an opportunity occurring and/or the magnitude of results being beneficial,” which directly matches the definition ofEnhance. For example, in a VM study, enhancing an opportunity might involve marketing a new feature to increase its adoption rate (probability) or improving its design to maximize savings (magnitude).
Option A (Exploit) is incorrect because exploiting ensures the opportunity happens, not necessarily increasing its probability or magnitude.
Option B (Share) is incorrect because sharing involves collaboration, not directly increasing probability or magnitude.
Option C (Mitigate) is incorrect because mitigation applies to threats, not opportunities.
Option D (Enhance) is correct, as it focuses on increasing the probability and/or magnitude of an opportunity’s benefits.
What function must a pen or pencil perform?
Options:
Write documents
Color surface
Mark surface
Convey message
Answer:
CExplanation:
Function Analysis in Value Methodology involves identifying and classifying functions using verb-noun combinations, as taught in the VMF 1 course (Core Competency #2). The basic function of an item is its primary purpose—what it must do to fulfill its intended use. According to SAVE International’s Value Methodology Standard, “functions should be defined in broad, measurable terms (verb-noun format) to capture the core purpose.” For a pen or pencil, the basic function is the most fundamental action it performs. A pen or pencil mustmark surface, as this captures the essential action of leaving a visible trace (e.g., ink or graphite) on a surface (e.g., paper), which is the core purpose of both tools, regardless of their specific use (writing, drawing, etc.).
Option A (Write documents) is incorrect because writing documents is a specific application, not the basic function; a pen can also draw or mark without writing a document.
Option B (Color surface) is incorrect because coloring implies adding color, which is not the primary function of a standard pen or pencil (e.g., a pencil typically uses graphite, not color).
Option C (Mark surface) is correct, as it defines the basic function of a pen or pencil in the broadest, most fundamental terms, encompassing all uses (writing, drawing, marking).
Option D (Convey message) is incorrect because conveying a message is a higher-level outcome, not the basic function; a pen can mark a surface without conveying a message (e.g., a random scribble).
Which phase enables the VM team to select viable ideas?
Options:
Function Analysis
Presentation
Evaluation
Development
Answer:
CExplanation:
The Value Methodology (VM) Job Plan, as outlined in the VMF 1 course and SAVE International’s Value Methodology Standard, consists of six phases, one of which is the Evaluation Phase, where the VM team selects viable ideas. In the Evaluation Phase, the team assesses ideas generated during the Creative Phase to determine their feasibility, cost impact, and alignment with project goals. According to the VMF 1 Core Competency #3 (Value Methodology Job Plan), the Evaluation Phase involves “evaluating the ideas for their potential to improve value, using criteria such as cost savings, performance, quality, and feasibility, to select the most viable alternatives for further development.” Tools like weighted evaluation matrices may be used to rank ideas systematically.
Option A (Function Analysis) is incorrect because this phase focuses on identifying and analyzing functions, not selecting ideas.
Option B (Presentation) is incorrect because this phase involves communicating recommendations to stakeholders, after ideas have already been selected and developed.
Option C (Evaluation) is correct, as it is the phase where the VM team filters and selects viable ideas based on defined criteria.
Option D (Development) is incorrect because this phase involves refining selected ideas into actionable proposals, which happens after the Evaluation Phase.
Which of the following letters represents the scope lines?
Options:
A
B
C
D
Answer:
BExplanation:
The diagram provided is a Function Analysis System Technique (FAST) diagram, a key tool in Value Methodology’s Function Analysis phase, as taught in the VMF 1 course (Core Competency #2). FAST diagrams map the relationships between functions of a system, with the horizontal axis showing the “how-why” logic (critical path) and the vertical axis showing supporting functions. The vertical demarcations on the left and right of a FAST diagram are calledscope lines, which define the boundaries of the study. According to SAVE International’s Value Methodology Standard, “scope lines indicate the limits of the system or project being analyzed, separating the functions within the study’s scope from external functions or assumptions.” This was previously established in Question 15, where scope lines were identified as the correct term for these vertical demarcations.
In the FAST diagram:
The dashed vertical lines on the left and right are labeledB(left) andD(right). These lines define the scope of the study, with functions inside the lines (e.g., E, F, G, J, L, M, N, O) being within the study’s focus, while functions outside (e.g., P, Q, R) are external assumptions or higher-level objectives.
Ais a horizontal line at the bottom, representing the boundary of the diagram but not the scope lines.
Cis an arrow indicating the direction of the “why” axis (left), not a scope line.
Since the question asks for the letter that “represents the scope lines,” and both B and D are scope lines, the correct answer must be one of these. However, the options only allow for one letter to be selected, and in FAST diagramming convention, the left scope line (B) is often emphasized as the primary boundary for defining the study’s starting point (e.g., the higher-order function E, as identified in Question 18). Thus,Bis the most appropriate choice among the options provided.
Option A (A) is incorrect because A is a horizontal line, not a vertical scope line.
Option B (B) is correct, as B is the left vertical scope line, marking the boundary of the study’s scope.
Option C (C) is incorrect because C is an arrow, not a scope line.
Option D (D) is also a scope line (the right boundary), but since only one letter can be selected and B is the left scope line (often the primary focus in FAST diagramming), B is chosen. If the question intended to allow both B and D, the phrasing would need adjustment.
How many phases are in the VM Job Plan?
Options:
3
6
7
8
Answer:
BExplanation:
The Value Methodology (VM) Job Plan is a structured, systematic process central to Value Methodology, as defined in the Value Methodology Fundamentals 1 (VMF 1) course and SAVE International’s Value Methodology Standard. According to these sources, the VM Job Plan consists ofsix phases: Information, Function Analysis, Creative, Evaluation, Development, and Presentation. These phases ensure a disciplined approach to analyzing functions, generating ideas, evaluating alternatives, and presenting value-enhancing recommendations.
Information Phase: Collect and analyze data on project scope, costs, constraints, and objectives to establish a baseline for the study.
Function Analysis Phase: Identify, classify, and analyze functions (e.g., basic, secondary) using tools like the Function Analysis System Technique (FAST) to understand their purpose and relationships.
Creative Phase: Generate a broad range of ideas to improve value through brainstorming or other creative techniques, focusing on alternative ways to perform functions.
Evaluation Phase: Assess the feasibility, cost impact, and benefits of ideas using criteria like performance, quality, and alignment with project goals.
Development Phase: Refine the most promising ideas into detailed, actionable proposals, including implementation plans and cost estimates.
Presentation Phase: Communicate recommendations to stakeholders through reports, presentations, or other deliverables to gain approval and facilitate implementation.
SAVE International’s VMF 1 course, which is a prerequisite for the VMA exam, explicitly teaches these six phases as part of Core Competency #3 (Value Methodology Job Plan). The standard is consistent across SAVE International’s documentation, including the Value Methodology Standard and certification guidelines. Options A (3), C (7), and D (8) do not match the official six-phase structure of the VM Job Plan.
What is the correct sequence of the last four phases of the Value Methodology Job Plan?
Options:
Development, Presentation, Evaluation, and Implementation
Evaluation, Development, Presentation, and Implementation
Evaluation, Development, Implementation, and Presentation
Development, Evaluation, Presentation, and Implementation
Answer:
BExplanation:
The Value Methodology (VM) Job Plan, as outlined in the VMF 1 course and SAVE International’s Value Methodology Standard, consists of six phases: Information, Function Analysis, Creative, Evaluation, Development, and Presentation. This was established in Question 1, where the VM Job Plan was confirmed to have six phases. The last four phases, therefore, are: Creative, Evaluation, Development, and Presentation. However, the options include “Implementation,” which is not a formal phase in the standard VM Job Plan but is often considered a post-study activity (e.g., in the post-study phase, where recommendations are implemented). For the purposes of the VMA exam, which focuses on the VMF 1 curriculum, Implementation is sometimes treated as an extension of the Presentation Phase, where the team ensures stakeholder buy-in and facilitates the transition to implementation.
Thus, the correct sequence of the last four phases, interpreting Implementation as the post-Presentation activity, is:
Creative(third phase, but the first of the last four).
Evaluation(fourth phase): Assess ideas for feasibility and value improvement.
Development(fifth phase): Refine selected ideas into actionable proposals.
Presentation(sixth phase): Present recommendations to stakeholders for approval and implementation.
Implementation: Follows Presentation as a post-study activity to execute the recommendations.
Option A (Development, Presentation, Evaluation, and Implementation) is incorrect because Evaluation must precede Development—ideas are evaluated before being developed into proposals.
Option B (Evaluation, Development, Presentation, and Implementation) is correct, as it follows the VM Job Plan’s sequence and includes Implementation as the post-study step.
Option C (Evaluation, Development, Implementation, and Presentation) is incorrect because Presentation (delivering recommendations) must occur before Implementation.
Option D (Development, Evaluation, Presentation, and Implementation) is incorrect because Development cannot precede Evaluation in the VM Job Plan.
The VM Job Plan provides a structured sequence of phases designed to leverage which of the following types of thinking?
Options:
Divergent and abstract
Convergent and abstract
Critical and divergent
Convergent and divergent
Answer:
DExplanation:
The Value Methodology (VM) Job Plan, as outlined in the VMF 1 course (Core Competency #3: Value Methodology Job Plan), is a structured sequence of six phases designed to leverage bothdivergentandconvergentthinking. According to SAVE International’s Value Methodology Standard, “the VM Job Plan alternates between divergent thinking (to generate a wide range of ideas) and convergent thinking (to narrow down and refine those ideas).” Divergent thinking is used in the Creative Phase to brainstorm as many ideas as possible without judgment, while convergent thinking is applied in the Evaluation and Development Phases to analyze, select, and refine the best ideas into actionable proposals. This combination ensures a balance between creativity and practicality, maximizing value improvement.
Option A (Divergent and abstract) is incorrect because, while divergent thinking is used, “abstract” is not a specific type of thinking emphasized in the VM Job Plan.
Option B (Convergent and abstract) is incorrect because it omits divergent thinking, which is critical in the Creative Phase.
Option C (Critical and divergent) is incorrect because, while critical thinking is involved in Evaluation, the VM Job Plan specifically emphasizes convergent thinking to narrow down ideas.
Option D (Convergent and divergent) is correct, as it captures the dual thinking types leveraged across the VM Job Plan phases.
Which of the following best describes a VM study?
Options:
It is a structured effort using the VM process to improve value
Must be led by a Certified Value Specialist
Is undertaken after the design is completed
Is considered a business improvement best practice
Answer:
AExplanation:
A Value Methodology (VM) study is a structured effort that applies the VM process to improve the value of a project, product, or process by optimizing the function-to-cost ratio. According to SAVE International’s Value Methodology Standard, a VM study is defined as “a systematic application of recognized techniques by a multi-disciplined team to identify the functions of a project or process, establish a worth for each function, and develop alternatives to achieve those functions at the lowest overall cost while maintaining performance.” The VMF 1 course emphasizes that a VM study follows the six-phase VM Job Plan (Information, Function Analysis, Creative, Evaluation, Development, and Presentation) to systematically improve value, making it a structured effort.
Option A (structured effort using the VM process) directly aligns with SAVE International’s definition of a VM study, focusing on the systematic application of the VM process to enhance value.
Option B (must be led by a Certified Value Specialist) is incorrect because, while a Certified Value Specialist (CVS) often leads VM studies, the VMF 1 course and VMA certification allow non-CVS team members to participate in and contribute to VM studies under guidance, meaning it’s not a requirement.
Option C (undertaken after the design is completed) is incorrect because VM studies can be conducted at various stages of a project lifecycle—concept, design, or implementation—not only after the design is completed. The VMF 1 course highlights that early application of VM yields the greatest benefits.
Option D (business improvement best practice) is a broader statement and not specific to the definition of a VM study, though VM can contribute to business improvements. It does not best describe a VM study compared to Option A.
The Pareto Principle as applied in the Value Methodology means:
Options:
20% of risks impact 80% of elements
20% of elements represent 80% of the cost
80% of functions represent 20% of components
80% of the whole includes 20% of the resources
Answer:
BExplanation:
The Pareto Principle, often referred to as the 80/20 rule, is a concept used in Value Methodology to focus efforts on the most impactful areas during cost analysis. In the context of VM, as taught in the VMF 1 course (Core Competency #4: Cost Analysis), the Pareto Principle is applied to identify high-cost areas that offer the greatest potential for value improvement. According to SAVE International’s Value Methodology Standard, “the Pareto Principle in VM states that approximately 20% of the elements (components, functions, or items) typically account for 80% of the total cost.” This allows the VM team to prioritize their efforts on the small number of elements that drive the majority of the cost, thereby maximizing value improvement (function/cost). For example, in a project, a few components (like a specialized motor in a machine) might represent the bulk of the cost, and optimizing those components can yield significant savings.
Option A (20% of risks impact 80% of elements) is incorrect because the Pareto Principle in VM focuses on cost distribution, not risk impact.
Option B (20% of elements represent 80% of the cost) is correct, as it directly aligns with the application of the Pareto Principle in VM cost analysis.
Option C (80% of functions represent 20% of components) is incorrect because it reverses the principle and does not reflect the cost-focused application in VM.
Option D (80% of the whole includes 20% of the resources) is incorrect because it misapplies the principle and is too vague for VM’s specific use of Pareto in cost analysis.
Function E is the:
Options:
Secondary Function
Required Secondary Function
Basic Function
Higher Order Function
Answer:
DExplanation:
The diagram provided is a Function Analysis System Technique (FAST) diagram, a key tool in Value Methodology’s Function Analysis phase, as taught in the VMF 1 course (Core Competency #2). FAST diagrams map the relationships between functions of a system, with the horizontal axis showing the “how-why” logic (critical path) and the vertical axis showing supporting functions. Functions are classified as basic, secondary, required secondary, or higher-order based on their position and role in the diagram. According to SAVE International’s Value Methodology Standard, “the basic function is the primary purpose of the system, typically found on the critical path; higher-order functions are the reasons why the basic function exists, located to the left of the basic function; secondary functions support the basic function and are often vertical; and required secondary functions are necessary to achieve the basic function.”
In the FAST diagram:
The critical path (horizontal, marked by Y in an earlier question) runs from E to F to G to J to L to M to N to O, representing the main sequence of functions.
Scope lines (B and D) define the study’s boundaries, as identified in Question 15.
Function E is positioned at the far left of the critical path, just inside the left scope line (B).
In FAST diagramming:
Thebasic functionis the primary purpose of the system, typically located near the center or right of the critical path within the scope lines. Here, it would likely be a function like J or L, which is central to the system’s purpose.
Thehigher-order functionis the reason “why” the basic function exists and is located to the left of the basic function, often at or near the left scope line. Function E, being the leftmost function on the critical path, answers “why” the subsequent functions (F, G, etc.) exist, making it the higher-order function.
Secondary functions(e.g., S, T, U, K) are vertical, supporting the critical path, and are not on the main horizontal sequence.
Required secondary functionsare secondary functions essential to the basic function, but E is on the critical path, not a vertical supporting function.
Thus, Function E, as the leftmost function on the critical path, is thehigher-order function, representing the overarching objective or need that the system fulfills.
Option A (Secondary Function) is incorrect because secondary functions are off the critical path (e.g., S, T, K), while E is on the critical path.
Option B (Required Secondary Function) is incorrect because E is not a secondary function; it is on the main path, not a supporting vertical function.
Option C (Basic Function) is incorrect because the basic function is typically more central on the critical path, not at the far left.
Option D (Higher Order Function) is correct, as E’s position at the left of the critical path indicates it is the higher-order function, answering “why” the system exists.
