Strategy.

The framework

1. 01

   Define the core before you leave it.

   An adjacency is measured from the core, so a misdefined core makes every measurement wrong — and most companies flatter themselves broader than they are. Write the core as a sentence someone could verify from your numbers: which customers actually generate the profit, which product, through which channel, won by which capability. Then check its health, because the ladder is not an escape route: a striking share of failed adjacencies trace back to a core that was under attack or still had headroom, and expansion drained exactly the attention the core needed. You climb from strength or you don't climb.

2. 02

   Count the steps, not the market size.

   For each candidate move, ask five questions: new customer? new product? new channel? new geography? new capability or cost structure? Every 'yes' is a step. At one step, the move shares almost everything with the core — existing customers pull you in, existing capabilities carry you, and what you don't know is contained. At two, the unknowns start multiplying each other. At three or more you are effectively a startup wearing an incumbent's cost base, without the founder's focus or the founder's cheap failure. The discipline when a distant market genuinely matters is not to abandon it but to refuse the leap: find the sequence of one-step moves that points the same direction.

3. 03

   Build the repeatable formula.

   Zook's winners didn't make one brilliant move; they made the same shaped move repeatedly. Nike's expansion ran sport by sport to the same playbook — establish credibility in footwear with the athletes who define the sport, extend into apparel, then equipment, then take the whole position international, then start the next sport and run it again. Each repetition made the machine better: integration got faster, judgement got sharper, learning got cheaper — which is why the second and third uses of a formula succeed far more often than anyone's first attempt at anything. Ask of your next move: is this the second use of a playbook, or a brand-new game? A formula compounds. One-off adventures mostly teach your team that expansion hurts.

4. 04

   Sequence the rungs — and set the tripwires before you climb.

   Turn direction into a ladder: each rung one step from the rung before, each with a test that must pass before the next is attempted. Decide in advance what evidence means advance and what evidence means retreat, and write both down now — because once you're on the ladder, sunk cost and pride will argue eloquently for one more rung, and they will be the loudest voices in the room. This isn't caution for its own sake. A chain of one-step moves reaches the distant market too; it just arrives carrying earned customers and earned capabilities instead of hope.
