Video Variants for CrowdRE: How to Create Linear Videos, Vision Videos, and Interactive Videos

In CrowdRE, heterogenous crowds of stakeholders are involved in requirements elicitation. One major challenge is to inform several people about a complex and sophisticated piece of software so that they can effectively contextualize and contribute their opinions and insights. Overly technical or boring textual representations might lead to misunderstandings or even repel some people. Videos may be better suited for this purpose. There are several variants of video available: Linear videos have been used for tutorials on YouTube and similar platforms. Interactive media have been proposed for activating commitment and valuable feedback. Vision videos were explicitly introduced to solicit feedback about product visions and software requirements. In this paper, we describe essential steps of creating a useful video, making it interactive, and presenting it to stakeholders. We consider four potentially useful types of videos for CrowdRE and how to produce them. To evaluate feasibility of this approach for creating video variants, all presented steps were performed in a case study.
