Final answer:
A systemic approach with incentive systems is more likely to create an ethical organizational culture by aligning employees' actions with organizational goals, as opposed to oversight or compliance-based approaches.
Step-by-step explanation:
The question pertains to which approach to corporate governance is more likely to foster an ethical organizational culture. Among the options provided, a systemic approach with incentive systems may be most conducive to creating ethical behavior within an organization. This method encourages a culture of ethics by aligning the incentives of the employees with the goals of the organization, which includes ethical performance. In contrast, oversight committees focused on rules and a board focused on legal and regulatory compliance tend to enforce a minimum standard of behavior but do not necessarily promote a culture that goes beyond mere compliance. The failure of corporate governance in the case of Lehman Brothers, which did not provide accurate financial information about their operations, illustrates the importance of a governance system that is embedded throughout the organizational culture rather than one that merely enforces rules.
