Fundamentals of System Engineering

Question 1

Systems Engineering

Answer 1

A methodical, multi-disciplinary approach for the design, realization, technical management, operations, and retirement of a system.

Question 2

A System

Answer 2

A combination of elements that function together to produce the capability required to meet a need. The elements include all hardware, software, equipment, facilities, personnel, processes, and procedures needed for this purpose; that is, all things required to produce system-level results. The results include system-level qualities, properties, characteristics, functions, behavior, and performance.

Question 3

Systems Engineering Engine

Answer 3

A series of NASA processes used to develop and realize end products.

Question 4

Verification

Answer 4

Verification of a product shows proof of compliance with requirements—that the product can
meet each “shall” statement as proven though performance of a test, analysis, inspection, or demonstration (or combination of these

Question 5

Validation

Answer 5

Validation of a product shows that the product accomplishes the intended purpose in the intended environment—that it meets the expectations of the customer and other stakeholders as shown through performance of a test, analysis, inspection, or demonstration

Question 6

Which three elements must systems engineering address equally and integrate into the design?

Answer 6

Hardware, Software, and Human Systems

Question 7

What is functional decomposition?

Answer 7

Functional decomposition is the examination of a function to identify sub functions necessary for the accomplishment of that function and functional relationships and interfaces.
