  Case Management supports knowledge workers in performing knowledge-intensive
processes in a flexible way. An essential ingredient of Case Management are
template processes that are modified for a specific case to suit the context of
that case. Modifying templates results in many different yet related process
variants. However, modifying a template is time consuming and may lead to
errors. This paper defines an approach to extract fragments, called features,
from artifact-centric process variants in case management. By composing the
extracted features, the input variants and other process variants can be
derived. This way, complex artifact-centric process variants can be designed
more efficiently and their quality improves, since well-known modifications are
applied.
