This study shows how an optimisation model DEA can be applied to corporate social responsibility in the company-wide capability for people, processes, and resources to meet social obligations to all stakeholders under the guise of corporate citizenship. The data used are the sanitized scores of the empirical results from an Australian bank study. The DEA model was able to identify 11 decision making units, from a cohort of 231, that were leading exponents of the behavioural characteristics required to be rated 100% for satisfying corporate social responsibility criteria. The firm could use such findings to investigate why these units succeeded so well when others floundered and this analysis can provide valuable information for developing an efficient organizational structure for the company for achieving good corporate governance.
