What it shows
Porter’s generic strategies as a 2 × 2 grid. The type of competitive advantage, lower cost or differentiation, runs across the top; the competitive scope runs down the side, from a broad target (most or all segments) to a narrow one (one or a few segments).
Each cell names the strategy, says what it means and gives a fictional example from one industry, coffee roasting, so the grid compares rivals rather than unrelated businesses. A dashed box over the center marks “stuck in the middle”, Porter’s term for a firm that makes no clear choice.
How to read it
Read a cell by its column (the type of advantage) and its row (how broad the target is). A mass-market roaster whose coffee is in every supermarket competes on lower cost across the whole market: cost leadership.
A premium national coffee brand, sold everywhere at a higher price, has a differentiation strategy. A low-price roaster serving offices only has a cost focus.
Northfield Coffee Roasters sells traceable single-origin beans to specialty cafes and subscribers, a segment that pays more for them. That is differentiation focus.
Porter argued that a firm should choose one. Critics point to firms that manage low cost and differentiation together, the debate the stuck-in-the-middle box opens.
The four strategies
- Cost leadership: the lowest cost in the industry, serving most segments.
- Differentiation: a product that buyers across the industry value and pay more for.
- Cost focus: lower cost than rivals within one or a few segments.
- Differentiation focus: a product that one segment values and pays more for.
Ways to use it in teaching
Ask students to place three real firms from one industry on the grid and defend each placement.
Use the stuck-in-the-middle box to open a debate on hybrid strategies, with Miller’s (1992) “The generic strategy trap” as the opposing reading.
Set Northfield’s cell beside the balanced scorecard example, which names differentiation focus as its strategy. Which of its measures would a cost leader keep, and which would it replace with cost measures such as cost per pound roasted?
