MEM Systems Engineering 1 — Questions and Answers
Question 1: What is the primary goal of systems engineering in complex projects?
- Minimizing the number of software components
- Ensuring all system elements work together to satisfy stakeholder requirements (Correct answer)
- Reducing project team size
- Maximizing hardware performance in isolation
Correct answer: Ensuring all system elements work together to satisfy stakeholder requirements
Systems engineering integrates all aspects of a complex system to ensure that design, development, and operation meet defined stakeholder requirements holistically.
Question 2: In systems engineering, what does a 'requirements baseline' represent?
- The minimum budget approved for a project
- A formally reviewed and agreed-upon set of requirements controlling further development (Correct answer)
- The initial rough estimate of system needs
- A list of all rejected requirements
Correct answer: A formally reviewed and agreed-upon set of requirements controlling further development
A requirements baseline is a formally approved configuration of requirements used as a reference point for managing changes throughout the system lifecycle.
Question 3: What is 'functional decomposition' in systems engineering?
- Breaking down system functions into smaller, manageable sub-functions (Correct answer)
- Removing unnecessary functions to simplify the system
- Decomposing a system into its physical hardware components only
- Analyzing system failures and their root causes
Correct answer: Breaking down system functions into smaller, manageable sub-functions
Functional decomposition hierarchically breaks complex system functions into simpler sub-functions to facilitate design, allocation, and verification.
Question 4: Which document in systems engineering defines the high-level technical requirements a system must satisfy?
- Work breakdown structure (WBS)
- System requirements specification (SRS) (Correct answer)
- Project charter
- Risk register
Correct answer: System requirements specification (SRS)
The System Requirements Specification (SRS) formally documents the functional and non-functional requirements the system must meet to satisfy stakeholder needs.
Question 5: In the 'Vee model' of systems engineering, what activities occur on the right side of the V?
- Requirements definition and system architecture
- Integration, verification, and validation activities (Correct answer)
- Risk identification and mitigation planning
- Schedule and cost estimation
Correct answer: Integration, verification, and validation activities
The right side of the Vee model represents progressive integration, verification at each level, and final system validation against stakeholder requirements.
Question 6: What is the difference between verification and validation in systems engineering?
- Verification tests prototypes; validation tests final products
- Verification checks if the system was built right; validation checks if the right system was built (Correct answer)
- Validation occurs before verification in the development cycle
- They are interchangeable terms for quality assurance
Correct answer: Verification checks if the system was built right; validation checks if the right system was built
Verification ensures the system meets its specified requirements (built right), while validation confirms the system satisfies the actual user needs (right system built).
