Michael Porter (1980) originally developed the five-forces model as a way of evaluating the attractiveness (profit potential) of an industry. He described his analysis as being concerned with the ‘forces driving industry competition’.
This model can aid the category strategy-development process. Assessing all facets of potential supply competition provides a rounded view when deciding upon what action to take in order to gain a competitive advantage.
In any industry, whether it is domestic or international, or whether it produces a product or a service, the rules of competition are embodied in five competitive forces that Porter classified as follows:
Lack of competition improves profit potential in a market. Category managers therefore need to understand how to develop supply-market opportunities for their categories in order to improve their overall leverage.
Correct application of this model should be at the lowest level of category hierarchy (i.e. at the granular, microindustry level); otherwise the output could be too ‘broad brush’ and thus potentially meaningless.
This model has been the subject of some critical comment, largely surrounding the static nature of the framework. Category management in comparison is a proactive, dynamic and ongoing process.
It has also been argued that category managers tend to ‘fit’ a strategy around Porter’s five forces in order to accommodate the output, whereas a more modern approach is to ‘stretch’ a strategy – that is, be more lateral and forward thinking – in order to circumnavigate the market supply and demand parameters.
The following template can be used to analyse market forces and rivalry that might impact a category strategy:
