  The adequate use of documentation for communication is one challenge in
requirements engineering (RE). In recent years, several researchers addressed
this challenge by using videos as a communication mechanism. All of them
concluded that this way of using videos has the potential to facilitate
requirements communication. Nevertheless, software professionals are not
directors and thus do not necessarily know what constitutes a good video. This
lack of knowledge is one crucial reason why videos are still not an established
communication mechanism in RE. When videos shall be established in the RE
activities, practices, and techniques, requirements engineers have to acquire
the necessary knowledge to produce and use good videos on their own at moderate
costs, yet sufficient quality. In our research project ViViReq (see
Acknowledgment), we aspire to bridge this knowledge gap about what constitutes
a good video. Whether a video is good or not depends on its quality perceived
by its viewers. However, video quality is a rather ill-defined concept due to
numerous unspecified technical and subjective characteristics. As part of our
research plan, we develop a quality model for videos inspired by the idea of
Femmer and Vogelsang to define and evaluate the quality of videos as RE
artifacts. In addition to evaluating videos, this quality model can be used to
identify the relevant characteristics of videos for their specific purpose
which can be further used to specify requirements, their criteria for
satisfaction, and corresponding measures. Therefore, software professionals may
use the quality model as guidance for producing and using videos.
