16
Q

Design goal

A

set of top-level requirements. Often related to system attributes

17
Q

Good requirements must be

A 
Clear
Solution-neutral
Verifiable
Consistent
Complete
18
Q

Good requirements should be

A

Positively formulated
Quantifiable
Ambitious, but attainable

19
Q

5 rules for ADGs

A

what can be meassured first is in the lower level
Elements can only be attributes
Properties(values) or requirements are not part of the graph
no circular dependencies
direct vs indirect dependence

20
Q

House of Quality

A

Elements and their relations are systematically documented and visualized

21
Q

What is a solution-neutral requirement

A

Is formulated according to the what-not-how principle:

one should focus on what goals they want to accomplish and not how thez want to accomplish

22
Q

INUS condition

A

Insuficient but necessary part of an unnecesary but suficient condition

23
Q

Organization forms

A

1) Component-oriented
2) Project/product-oriented
3) Customer-Function-oriented
4) Matrix- organization

24
Q

Complete Solution Space

A

Set of all good designs

25
Q

Building Models

A

1) Function
2) Working Principle —> how it is performed
3) Component detail attributes

26
Q

How to come to solutions by abstractions

A

1) Concrete problem
2) Abstract problem
3) Several abstract solutions
4) Solution idea

27
Q

Function

A

states the action of a system upon an element, expressed as an input-output relationship

28
Q

Types of function models

A

Verbal description
Verbal and graphical description
Graphical description

29
Q

Function models summary

A

Represent products on a particular level of abstraction
Provide structure for design task
Supports common understanding

30
Q

Clustering summary

A

separate a system into clusters depending on their connectivities and mixed interfaces
—> organize complex systems

31
Q

sequencing connection types

A

serial
parallel
coupled

32
Q

What is a Pareto-optimal design

A

A design where no pareto improvement is possible.

Pareto improvement:
an improvement of an attribute without making another one worse

33
Q

3 modern design methods philosophies

A

1) design thinking
—> creative strategies designers use during the process of identifying problems designing solutions
2) lean (smart development)
—> improve virtually everything by deleting anything that does not bring value to the customer
3) agile
—> iterative approach: time-focusing way of achieving continuous value delivery aimed at executing tasks faster, adapting to changes easier
