very important characteristic of multi-staged configuration
is that when variants are selected in one stage, variants
from the next stage can be delimited because of the current
selection.
Figure 4.2 summarizes a process example to configure
and derive a Smart-Home system using a multi-staged
process. First, a building architect creates a domain model.
Then, a facilities designer creates a configuration based
on a facilities feature model. Finally, a software designer
createsanotherconfigurationbasedonanarchitecturalfeature
model.

4.3. Solution space issues
The solution space is concerned with the description of
a feasible solution to the problem using concrete software
patterns and adequate technology. Thus, the main issues
concerning the solution space dimension are i) the construction
of models,model transformations,textual descriptors,and core
assets to implement the variability captured in the problem
space, and ii) the design of an automated product derivation
dealing with multiple development stages with a range of
models and core assets.
