The purpose of an external audit is to develop a finite list of opportunities that could benefit a firm and threats that should be avoided. As the term finite suggests, the external audit is not aimed at developing an exhaustive list of every possible factor that could influence the business; rather, it is aimed at identifying key variables that offer actionable responses. Firms should be able to respond either offensively or defensively to the factors by formulating strategies that take advantage of external opportunities or that minimize the impact of potential threats.

 

External forces can be divided into five broad categories: 

 

• Economic forces

• Social, cultural, demographic, and natural environment forces

• Political, governmental, and legal forces.

• Technological forces

• Competitive forces
