A software product line is a set of software-

intensive systems sharing a common, managed

set of features that satisfy the specific needs of a

particular market segment or mission and that

are developed from a common set of core

assets in a prescribed way

Information visualization is the use of computer-supported, interactive, visual representations ofabstract data to amplify cognition.

Researches

21

Feature Modeling

affected by size of SPL

2D graph layouts are unable to fit large hierarchies on the screen

22

Feature Cone Tree

23

[Pablo Trinidad et al., 08]

Feature Cone Tree

24

[Pablo Trinidad et al., 08]

effective use of screen space

prioritizes the understanding of the topology

2D layouts

can be best

low effectiveness for balanced hierarchies

just a prototype25

Product Derivation

application engineering processes should be performed efficiently

the tool should support stakeholders in the process of product configuration

[Goetz Botterweck et al., 08]

VISIT-FC

29

[Goetz Botterweck et al., 08]

support an industrial SPL

integration between decisions, features and components

implements various techniques of human interaction

it is not integrated with IDE’s

30

ConfigurationWizard

31

[Rick Rabiser, 08]

ConfigurationWizard

32

[Rick Rabiser, 08]

integrated with Eclipse. Extensible

working with Siemens VAI

focus on stakeholders

it works for thousands of “decisions”?

33

Design

how a particular feature is realized?

which artifacts may be effectively used in

a variant?

34

MappingViews

35

[Florian Heidenreich et al., 08]

MappingViews

36

[Florian Heidenreich et al., 08]

37

views controlled by developer

support feature expressions

just a prototype

do not map realcomponents

Implementation

tracing features from the domain level to their implementation

the code that realizes a feature can be scattered across multiple units

38

CIDE tool

39

[Christian Kästner et al., 08]

CIDE tool

40

[Christian Kästner et al., 08]

series of case studies

(industrial SPL too)

colors are intuitive we are not able to recognize many colors

blend colors

41

Evolution

new variable features are introduced, no one is removed

how to ensure the minimum number of variable features?

42

Optimization of Variability

43

[Felix Loesch & Erhard Ploedereder, 07]

Optimization of Variability

44

[Felix Loesch & Erhard Ploedereder, 07]

the method is easy

case study in large industrial SPL visualization

generated for large SPL is complex

variability analysis is time consuming

45

Conclusion

46

Visualization has proven useful in SPL

Many researches on:

Product derivation

Variability management

47

Tools should be integrated

Gap on reactive approach
