Differentiation: giving the customer a reason other than price

1. When customers see two products as the same, the only reason left to pick one is the price, so the business is pushed into undercutting whoever is cheapest.
2. Every price cut narrows the gap between the price charged and the cost of making the item, so the business sells the same goods and keeps less from each sale.
3. Differentiation breaks that comparison by giving the customer something the rival does not offer, in the product itself, in the brand around it or in the service that comes with it.

How a business differentiates: six routes and how each one works

1. A business can build a difference in six places, and each one works on the customer in a different way.
   1. Design and appearance: the product looks or works differently from anything else on the shelf, and Dyson built its position on a bagless vacuum cleaner developed through over 5,000 prototypes.
   2. Quality and durability: a product built to last costs more to buy but less for every year it is used, which is what lets Dr Martens sell boots at a premium price.
   3. Brand and reputation: a name the customer already trusts removes the risk of trying something new, and Innocent sells smoothies above the supermarket own-brand price on friendly branding rather than on different fruit.
   4. A feature rivals lack: Tesco and Sainsbury's offer click and collect while Aldi and Lidl do not, so a shopper who needs a fixed pickup time has only one of them to go to.
   5. Customer service: staff who know the product, quick replies to a complaint and easy returns give a reason to come back to a small shop even when an online seller is cheaper.
   6. Packaging: distinctive packaging is recognised on a crowded shelf before the customer reads a word, and heavier or better-made packaging signals that the contents are worth more.

Why it matters: from a difference to money to reinvest

1. A differentiated product has no identical alternative for the customer to price-check it against, so the buyer is weighing up the difference instead of the pound saved.
2. That means the business can charge a higher price without losing the customer, which is how Dyson sells at a premium against cheaper vacuum cleaners that clean the same floor.
3. A higher price on the same cost per unit protects the margin, so more of every sale is left over once the costs of making and selling the product are paid.
4. That money funds new designs, better materials and more advertising, which renews the difference before rivals catch up and starts the whole chain again.

The unique selling point, and why it does not stay unique

1. The strongest form of differentiation is a unique selling point, meaning a feature no rival offers at all, which is covered as one of the five routes to added value in guide 1.1.3b.
2. What matters here is that a unique selling point decays, because the moment a rival copies it the price premium goes with it, so differentiation has to be renewed rather than achieved once, and how long the advantage lasts depends on how hard the difference is to copy.
   1. Easy to copy: a free delivery offer or an extra colour can be matched by a rival within a week, so the sales gained disappear and only the extra cost stays.
   2. Hard to copy: a reputation for durability built over decades, as Dr Martens has, or a genuinely better design like Dyson's, needs years, money and engineering a rival may not have.
3. Differentiating badly is worse than not bothering, because a difference customers do not actually value adds cost to every unit without adding a single sale.
4. A product that is different but worse loses outright, so the test is always whether this particular customer would pay more for this particular difference.
