Blue Ocean Strategy

Red oceans are existing industries with defined boundaries and known rules, where competitors fight for a share of a fixed demand and the water turns red. Blue oceans are untapped market space where demand is created rather than fought over.

The authors' claim is that the strategic literature — Porter's especially — is overwhelmingly about winning in red oceans, and that the more valuable question is how to stop competing.

Most strategy asks how to win the contest. This asks how to arrange not to be in it.

The book's central concept and its direct challenge to Porter. Value innovation means pursuing differentiation and low cost simultaneously — which Porter argues leaves a firm stuck in the middle.

Their mechanism for resolving this is the key move: cost is reduced by *eliminating* factors the industry competes on, while value is raised by introducing factors it has never offered. The two are achieved by changing what is offered, not by doing more of everything.

Their primary diagnostic: plot the factors an industry competes on against the level each player offers, producing a value curve.

Its usefulness is immediate — competitors' curves usually converge almost exactly, which makes visible how little differentiation actually exists in most industries. A blue ocean strategy has a curve with a visibly different shape rather than a higher one.

The four actions framework, applied to the factors on the canvas. Which factors the industry takes for granted should be eliminated? Which reduced well below standard? Which raised well above? Which created that the industry has never offered?

The elimination question is the one organisations resist and the one that makes the cost side work. Without it, the framework becomes a list of additions and the economics fail.

The elimination question is what pays for the rest. Skip it and you have a feature list, not a strategy.

Devmark’s reading — not a quotation from the book

Their method for finding blue oceans systematically rather than by inspiration: look across alternative industries, across strategic groups, across buyer groups, across complementary offerings, across functional and emotional appeal, and across time.

The buyer-group path is the most frequently productive — noticing that the purchaser, the user and the influencer are different people with different criteria, and that industries typically serve only one of them.

Rather than segmenting existing customers more finely, the authors argue for looking at three tiers of non-customers: those on the edge who use the industry minimally, those who have consciously refused it, and those who have never considered it.

The reasoning is that finer segmentation pushes toward customisation and smaller markets, while the commonalities among non-customers point toward scale.

Their strategic sequence — buyer utility, price, cost, adoption — insists that price is set before cost, with cost then engineered to hit a target margin. This inverts the common practice of costing up from what the product requires.

The adoption hurdles section, covering employees, partners and the general public, is unusually practical and often skipped by readers who stop after the frameworks.

The main methodological objection mirrors the one made of Collins: the cases are selected after success, and blue ocean attempts that failed are not in the sample, making the claimed success rate unverifiable.

A second objection is that several celebrated examples are arguably excellent execution in an existing market rather than new market space, and that the red/blue distinction is less clean in practice than on the page.

The authors present the two as opposed; most practitioners find they are not. Porter analyses the structure you are in; Kim and Mauborgne argue for changing which structure you are in.

Porter's own work on industry evolution already allows that structure can be reshaped. The honest reading is that this book supplies better tools for that specific move, not a replacement for structural analysis.

The strategy canvas is worth the book on its own — drawing your industry's value curves is a two-hour exercise that reliably produces an uncomfortable picture.

Then the four actions, with the discipline to answer the eliminate question honestly. Most organisations can name what to add and cannot name what to stop, and the framework only works when both are answered.
