Trade-offs & activity fit

What is Trade-offs & activity fit?

A trade-off is giving up one thing so you can do something else well. Activity fit means the things a business does help each other work better. Together, these choices form what Porter calls an 'activity system': a way of running the business in which the parts support each other. In 'What Is Strategy?', he argues that running efficiently is necessary, but a strategy also requires doing different things from competitors, or doing the same things differently. A lasting advantage depends on choices that are costly to copy and work best together. Rumelt calls for 'coherent action', meaning actions that support the same plan. Martin and Lafley likewise describe strategy as a set of choices that work together.

How Trade-offs & activity fit works

A competitor may be able to copy one thing you do. Getting the same benefit from the whole set of choices is harder: it would have to change how its own business works and give up parts of its existing strategy. These choices also guide the development of Process Power: ways of working that a company gets good at over time and competitors struggle to copy.
