What is judo strategy?
Judo strategy is a way for a smaller company to compete by turning a larger opponent's size and strengths against it. David Yoffie and Michael Cusumano described it in Harvard Business Review in 1999, drawing on principles from the martial art such as speed and flexibility. Yoffie expanded the idea with Mary Kwak in the 2001 book Judo Strategy. The challenger avoids a head-on contest it would lose.
Why it matters to a revenue leader
A regional services company can find itself bidding against national providers with more sellers and bigger brands. Size brings constraints. A national provider may be slow to change its service levels, or unwilling to cut price in one market for fear of cutting it everywhere. A revenue leader can win by competing where the larger rival's size makes it slow to respond.
Example
Fictitious numbersA fire protection company with 12 sellers competes with a national provider for multi-site retail accounts in its region. The national firm prices from one rate card across the country. The smaller company offers regional pricing and same-week deficiency repairs, and over a year it wins 6 of the 15 regional renewals it bids on.
"Which of our larger competitor's strengths would be hardest for it to change, and how do we compete in that gap?"
