Organizational resilience (OR) is rising in attention due to not just being a key solution for companies to cope with crises but also being closely tied to their long-term survival and growth. However, researchers acknowledge research gaps such as issues related to the comprehensiveness and accuracy of OR measuring tools, which also fail to specify the kind of crisis they cover. This study intended to develop a novel tool, considering both static (resource-based) and dynamic (capability-based) dimensions of OR, alongside all 4 strategic responses to crises to hedge expected and unexpected disruptions, aiming to enhance comprehensiveness, alongside eliminating redundancy among factors and assigning weight to improve accuracy. To this end, the structured focus group (FC) and best-worst method (BWM) were conducted with the participation of 6 experts to refine and augment as well as assign weight to the factors. The tool encompasses 8 factors distributed across three sets—direction with a weight of 0.222, execution with a weight of 0.317, and results with a weight of 0.460—collectively including 23 sub-factors and 86 indicators. The tool's validation was tested by assessing the resilience of five petrochemical companies and comparing it to the Altman-Z score calculated for each one. This tool enables decision-makers to precisely assess the resilience level of their organizations, identifying strengths and weaknesses more comprehensively and prioritizing areas for improvement.
