ASEP Exam — Questions and Answers
Question 1: In the ASEP body of knowledge, what distinguishes 'functional requirements' from 'non-functional requirements'?
- Functional requirements apply to hardware; non-functional requirements apply to software
- Functional requirements are verified by analysis; non-functional ones by inspection only
- Non-functional requirements are optional; functional requirements are mandatory
- Functional requirements describe what the system must do; non-functional requirements describe quality attributes like performance, reliability, or usability (Correct answer)
Correct answer: Functional requirements describe what the system must do; non-functional requirements describe quality attributes like performance, reliability, or usability
Functional requirements specify system functions (what it must do), while non-functional requirements specify quality attributes (how well it must do it).
Question 2: A systems engineer is analyzing a requirement that states: 'The system shall be user-friendly.' Which of the following characteristics of a good requirement is this statement primarily violating?
- Verifiable (Correct answer)
- Implementation-free
- Feasible
- Necessary
Correct answer: Verifiable
The term 'user-friendly' is subjective and cannot be objectively measured or tested. A good requirement must be verifiable, meaning there is a definitive way to determine if the system meets the requirement through inspection, analysis, demonstration, or test. To improve this, the requirement should be broken down into specific, measurable criteria, such as 'The system shall respond to user input within 0.5 seconds' or 'A new user shall be able to complete Task X within 5 minutes with no more than 1 error.'
Question 3: What is 'anchoring bias' in the context of engineering decision-making?
- Ignoring stakeholder input
- Over-relying on the first piece of information encountered when evaluating alternatives (Correct answer)
- Giving excessive weight to cost criteria
- Selecting the highest-weighted criterion as the sole decision driver
Correct answer: Over-relying on the first piece of information encountered when evaluating alternatives
Anchoring bias occurs when decision-makers over-rely on the first information they receive, skewing subsequent judgments and comparisons.
Question 4: How does the systems engineering process handle conflicts between cost, schedule, and technical performance?
- Schedule always takes priority
- Technical performance is always sacrificed first
- Cost always takes priority
- Through trade studies, stakeholder negotiation, and decision analysis that balance competing objectives based on project priorities (Correct answer)
Correct answer: Through trade studies, stakeholder negotiation, and decision analysis that balance competing objectives based on project priorities
Systems engineering uses trade studies, stakeholder negotiation, and structured decision analysis to balance cost, schedule, and performance based on documented project priorities.
Question 5: Which analysis technique evaluates the impact of a single component failure on overall system functionality?
- Design Structure Matrix (DSM)
- Monte Carlo simulation
- Fault Tree Analysis (FTA)
- Failure Mode and Effects Analysis (FMEA) (Correct answer)
Correct answer: Failure Mode and Effects Analysis (FMEA)
FMEA systematically examines each potential failure mode of every component and assesses its effect on the overall system.
Question 6: During integration, what is the purpose of regression testing after adding a new component?
- To reduce the total number of tests
- To verify that previously passing tests still pass after the new component is added (Correct answer)
- To generate documentation

Correct answer: A general term for any incompatibility between interfacing components in data formats, protocols, timing, or physical characteristics
Impedance mismatch broadly refers to any incompatibility between interfacing components, whether in data formats, communication protocols, timing assumptions, or physical characteristics.
Question 8: A project team for a new electric aircraft needs to track progress against the critical operational need for "long-endurance flight." They define a key measure, "Flight time in hours with maximum payload under standard atmospheric conditions," which they will track throughout development. This measure is best classified as a:
- Technical Performance Measure (TPM)
- Measure of Effectiveness (MOE) (Correct answer)
- Measure of Performance (MOP)
- Key Process Indicator (KPI)
Correct answer: Measure of Effectiveness (MOE)
A Measure of Effectiveness (MOE) quantifies how well a system achieves its intended purpose or mission objective from the end-user's perspective. "Flight time" directly reflects the system's operational effectiveness. In contrast, MOPs and TPMs measure specific performance attributes of the system or its components (e.g., battery energy density, motor efficiency) that contribute to the MOE.
