Errors are an inevitable by-product of human labour. Therefore, organizational learning from errors should be regarded as a strategic goal of HR development. Despite a large number of studies on organizational learning from errors, a thorough understanding of error-related learning processes at work is still missing. In the present article, we present the results of a literature review that was used to derive an integrated model of organizational learning processes in the consequence of errors and to develop the questionnaire to assess the error-related learning climate in organizations. The questionnaire was evaluated on a sample of 383 employees of two companies. Confirmatory factor analyses support the suggested structure of errorrelated learning climate. Further analyses stress the relevance of constructive error handling in organizations by revealing substantial links between error-related learning climate and the effectiveness of error learning, self-perceptions and error-related behaviours of team members, as well as group cohesion and certain aspects of team performance.
