  Regulatory compliance is a well-studied area, including research on how to
model, check, analyse, enact, and verify compliance of software. However, while
the theoretical body of knowledge is vast, empirical evidence on challenges
with regulatory compliance, as faced by industrial practitioners particularly
in the Software Engineering domain, is still lacking. In this paper, we report
on an industrial case study which aims at providing insights into common
practices and challenges with checking and analysing regulatory compliance, and
we discuss our insights in direct relation to the state of reported evidence.
Our study is performed at Ericsson AB, a large telecommunications company,
which must comply to both locally and internationally governing regulatory
entities and standards such as GDPR. The main contributions of this work are
empirical evidence on challenges experienced by Ericsson that complement the
existing body of knowledge on regulatory compliance.
