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.
