Answer 0

Systems Engineering is an interdisciplinary approach and means to enable the production of robust systems, on-time and on-budget

Question 1

What is a System?

Answer 1

A system is a set of interrelated subsystems and components which interact with one another in an organized fashion toward a common purpose.

Question 2

What are the four main groups a systems engineer interacts with?

Answer 2

Question 3

What is the purpose of the ECSS (European Commission for Space Standardisation)?

Answer 3

ECSS provides baseline working practices for systems engineering in line with eSA/EU/industry requirements and recommendations

Question 4

Sequential vs Centralised vs Concurrent Design

Answer 4

Sequential goes from on person to the next in sequence.
Centralised has people communicating to a manager in the center, but not to one another.
Concurrent has all teams communicating to everyone.
