Strategy.

The framework

1. 01

   Plot it honestly — and get relative share right.

   Relative market share is your share divided by your largest competitor's — above one means you lead, below one means you trail — and it is the detail self-plots fudge first, through absolute numbers and generously drawn markets. For an operating business the units on the plot are whatever you allocate cash and attention across: products, services, client segments, channels. If you can't measure share, use the honest proxies — is the market pulling demand towards you without you pushing, and are you the buyer's default or one option among several? A plot built on flattery produces a strategy built on the same.

2. 02

   Milk the cows — and stop reinvesting out of loyalty.

   A cash cow is a strong position in a market that has stopped growing, and its job is to release cash: defend the position at minimum cost, price for the strength you hold, and resist the redesigns and roadmap ambitions the market will no longer repay. The difficulty is emotional, because the cow is usually the founding product — the one the company still identifies with — so it keeps receiving investment sized to its history rather than its future. Every dollar of loyalty spent on a mature product is a dollar withheld from the bet that needed it. Run the cow on maintenance, and treat its surplus as the strategy budget.

3. 03

   Pick your question marks — feed one properly, starve the rest.

   High growth with low share is the expensive quadrant: a growing market demands cash just to hold position, so a question mark either gets funded hard enough to reach leading share or it drains you for years while going nowhere. Half-funding is the worst available option — you pay the full cost of competing in a growth market without ever buying the position that makes it pay — yet it is what evenly spread budgets produce by default. The discipline is to choose: back the one or two bets with a genuine route to leadership, and exit the others while they still have some value to someone else.

4. 04

   Read the dogs carefully — the matrix has blind spots.

   The label says exit, but Henderson's logic rests on the experience curve — the claim that share drives cost advantage — and that doesn't hold everywhere: a low-share business in a slow niche can be reliably profitable for decades if it throws off cash and consumes no attention. So test dogs on those two counts rather than on the label, and keep only the ones that pass both. Then remember the whole chart is a snapshot: markets stop growing, positions erode, this year's star is quietly becoming a cow. Re-plot each quarter, or you will run allocation rules written for a portfolio that no longer exists.
