is the most important activity in SPL development. It is a
transverse activity performed during the whole product line
development cycle.
Figure 2.4 summarizes the five main activities involved in
the two SPL engineering processes. In this figure, variability
management covers the entire domain engineering since
several kinds of variability and several stages are needed.
The core assets result from domain engineering; this is “for
re-use”, while product derivation re-uses the elements from
the core assets. The product configuration can be seen as

domain engineering. The production plan is the main activity
responsible for the derivation of each product. The following
sections detail these activities.

Several dimensions are interesting for SPLE: the adoption
of SPLE,the development process,the re-use organization,and
the technical aspects.
