Many organizations rely on culture surveys to gather feedback on what’s working well, what’s not, and how to strengthen the functioning of the organization. Relatively few surveys have been validated, which means that they may give false feedback on how to improve business results. Unless scores on the instrument correlate with performance, it is not reasonable to assume that efforts to improve scores will translate into business results. Dr. Krause and Kristen Bell have a long-standing commitment to validating culture assessment tools. We are particularly proud of the work we did in the 1990’s with psychologist Dr. David Hofmann, to identify characteristics of organizational culture that predicted safety performance. The innovation process was high-quality and highly efficient: It began with a review of published academic research. New research needed only to select, model and validate a set of scales that would become an effective organizational culture assessment tool for safety. Similar tools have since been developed and validated by US government agencies and are in the public domain. We are extremely proud of the quality of this work, and the broad use it enjoys today.
