Q

What is synthesis?

A

Modifying or combining existing systems to satisfy stated needs, it requires good logic and good knowledge of existing system. Can we combine existing systems without too much baggage?

Q

What is discovery

A

Leverage knowledge of existing architectures to discover a new one. This requires knowledge of existing systems and abstraction skills. What are the good or bad properties of the given architecture?

17
Q

Functional Analysis definition

A

A decomposition of each high level function of a system (identified in requirements analysis) into sets of lower-level function

18
Q

What is a PBS?

A

Product Breakdown Structure. Where you are going?

19
Q

What is a PBS often called?

A

System Hierarchy

20
Q

What is WBS?

A

Work Breakdown Structure, it is built from PBS

21
Q

What is WBS defined by?

A

Results and outcomes, not actions.

22
Q

What does PBS contain?

A

It contains all products and deliverable to make a final product

23
Q

What does PBS begin with?

A

It begins with the final product. ex: Space shuttle

24
Q

Baseline definitions: INCOSE?

A

Baselines are business, budget, functional, performance and physical reference points for maintaining development and control.

25
Q

NASA baseline definition?

A

A baseline identifies an agreed to description of attributes of a configuration item (CI) at a point in time and provides a known configuration to which changes are addressed.

26
Q

What are NASA’s four baselines?

A

Functional, allocated, product, as deployed.
