Jeanette is a researcher at RISE Metrology. She works for and do researcher about that the same underlying metrological principles from physical sciences should be applied also for human-based measures, i.e. categorical quantities. Those methods are sparsely used, which gives unreliable decision bases. Thus, an appraisal is needed to provide quality assured measures for information, comparisons and decision-making. In turn, this can be used to identify and prioritize the most effective development activities and innovations.
