SSE definition

Question 1

Could you qualify SE? (2 elements)

Answer 1

1. a robust approach to the design, creation, and operation of systems.
2. ubiquitous and necessary part of the development of every space project.

Question 2

What is the function of SE?

Answer 2

to guide the engineering of complex systems.

Question 3

How is this approach?

Answer 3

This approach is iterative, with several increases in the resolution of the system baselines (which contain requirements, design details, verification plans and cost and performance estimates).

Question 4

The approach of SE consists of: (5 elements)

Answer 4

1. identification and quantification of system goals
2. creation of alternative system design concepts
   performance of design trades
   3.selection and implementation of the best design
   4.verification that the design is properly built and integrated
3. assessment of how well the system meets the goals

Question 5

What is a system?

Answer 5

a system is an integrated composite of people, products, and processes that provide a capability to satisfy a stated need or objectives

Question 6

Provides examples of systems: (4 elements)

Answer 6

1. Space Shuttle Main Engine vs. a collection of parts
2. Space Shuttle Orbiter with engines and avionics
3. Space Shuttle Orbiter with solid rocket boosters and external fuel tank
4. Space Transportation System (STS) with payload, launch pad, mission controllers, vehicle assembly facilities, trainers and simulators, solid rocket booster rescue ships

Question 7

How SE helps to solve problems? (2 elements)

Answer 7

1. Most space projects struggle keeping to their cost and schedule plans. Systems engineering helps reduce these risks.
2. Systems engineering decomposes projects in both the product and time domain, making smaller problems that are easier to solve.

Question 8

Could you describe SE? (4 elements)

Answer 8

1. Systems engineering is an interdisciplinary engineering management process to evolve and verify an integrated, life-cycle balanced set of system solutions that satisfy customer needs.
2. Systems engineering is a standardized, disciplined management process for development of system solutions that provides a constant approach to system development in an environment of change and uncertainty.
3. It also provides for simultaneous product and process development, as well as a common basis for communication.
4. Systems engineering ensures that the correct technical tasks get done during development through planning, tracking and coordinating.

Question 9

Could you describes SE major activities:

Answer 9

1. Development phasing that controls the design process and provides baselines that coordinate design efforts.
2. A systems engineering process that provides a structure for solving design problems and tracking requirements flow through the design effort.
3. Life cycle integration that involves the customers in the design process and ensure that the system developed is viable throughout its life.
