and selecting a target technological platform. The effects on
template models, which are used as starting core assets to
derive products, are specified in the model transformations.
Therefore, the effects must be expressed in terms of the
model transformations. What model transformations must be
used, and the execution ordering required to include selected
variants?

approach [WAG 08b]
The selection of the groups of model transformations
to be used is defined from the selected variants, i.e. the
model elements included in the configuration models, and the
