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

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
