Corporate risk management has traditionally focused on mitigating the impact of external factors over which a company has no control. But what about internal factors? Australian School of Business professor Lex Donaldson has developed Organisational Portfolio Analysis (OPA), a new approach that identifies the risks within a company's individual business units and reveals how their fluctuations interact with overall company risk and performance. OPA can deliver fresh insights into the dynamics and behaviour of a corporation. By better understanding sources of corporate risk, they can be managed and used to drive profits.
