Wal-Mart started as a single discount store and has grown into one of the largest retailers. It uses an ends-driven ethical approach where actions are judged based on their outcomes. Wal-Mart's management code of ethics applies to all employees involved in purchasing and aims to ensure honesty, confidentiality, and avoiding conflicts of interest. The board of directors' code governs board members' conduct during business. Managers must comply with applicable laws and regulations. Wal-Mart may need to modify its existing code to align with changes in laws and regulations.
