How it works
Every statement is written so that agreement means a stronger force. Each force’s score is the mean of its statements on a 1 to 5 scale.
Industry attractiveness = 6 − mean of the five force scores
High at 3.67 or above, moderate from 2.33, low below 2.33
The radar chart shows the shape of the pressure: a large, even shape means a tough industry, and one long spike points to the force to manage first. Forces scoring 3.5 or more are listed as the main pressures on profit.
Frequently Asked Questions
What are Porter's Five Forces?
Porter's Five Forces is a framework for judging how attractive an industry is.
