Abstract—Collection of information after incidents is regularly done through pre-printed incident report forms. These tend to be incomplete; frequently lack essential information. One consequence is that reports with inadequate information, that do not fulfil analysts’ requirements, are transferred into the analysis process. To improve, we used theory in design science and designed a new incident reporting form, based upon witness psychology, interview and questionnaire research and with focus on analysts’ within safety science requests. We have previous conducted three experiments to evaluate the new form, built upon a design science hierarchy. The new form can capture knowledge, regardless of the incidents character or contex. The aim in this paper is to describe how design science viz. a design hierarchy was used to construct a new collection form, in purpose to improve a minor artefact frequently used in safety science.
