This essay examines the challenges faced by managers at the Commonwealth Bank of Australia (CBA) in navigating a complex business environment influenced by government regulations and internal organizational dynamics. It discusses the impact of the Australian government's regulatory interventions, particularly the Banking Royal Commission, on the bank's operations and profitability. The essay further analyzes the managerial functions within CBA, drawing upon Henri Fayol's five principles of management—planning, organizing, commanding, coordinating, and controlling—to assess how managers can effectively address organizational issues and strategically position the bank for future growth amidst increasing complexity and regulatory scrutiny. The report concludes that Fayol’s five principles of management is considered to be the best possible solution for CBA to mitigate its expense issue and balance the revenue effectively with the help of the managerial decision making.
