  Evidence shows that software development methods, frameworks, and even
practices are seldom applied in companies by following the book. Combinations
of different methodologies into home-grown processes are being constantly
uncovered. Nonetheless, an academic understanding and investigation of this
phenomenon is very limited. In 2016, the HELENA initiative was launched to
research hybrid development approaches in software system development. This
paper introduces the 3rd HELENA workshop and provides a detailed description of
the instrument used and the available data sets.
