During my conversations with CEOs, it always comes to a point where they say: “I want to leave a legacy.” Any CEO would be satisfied with the business legacy left by Ingvar Kamprad, the IKEA founder who died last weekend.

Famous for its Allen wrench-assembled flat-pack furniture, Swedish meatballs, and the maze-like shopping routes through its showrooms, it hit upon a winning formula. It provided a differentiated offering that disrupted the industry at the time: affordable, build-it-yourself home furnishings sold in massive stores built on cheap, out-of-town real estate.
