Hambrick and Fredrickson's Strategy Diamond
The Strategy Diamond forces you to answer five questions about a strategy at once - where you compete, how you'll get there, what makes you different, in what order, and how you'll make money - so the pieces have to fit together, not just sound good separately.
Four questions - Arenas, Vehicles, Differentiators, Staging - fan out around Economic Logic, the one that has to tie the other four together.
Reach for this when…
- A strategy document reads as a list of good ideas that don't actually connect to each other.
- You have a clear 'what' but no answer for how it makes money.
- Two initiatives are quietly competing for the same resources because nobody sequenced them.
How to run it
- Arenas: name exactly where you will compete - which markets, products, segments.
- Vehicles: decide how you'll get there - build, buy, partner, joint venture.
- Differentiators: state specifically what makes you win there, not 'quality' or 'service'.
- Staging: sequence and pace the moves - what happens first, what waits.
- Economic Logic: show precisely how this makes money, not just how it makes revenue.
A worked example
Situation. Javiera Rojas runs a boutique wine export business near Valparaiso, Chile, and her strategy on paper was simply 'grow international sales'.
Applied. Running it through the five diamond questions, she picked one arena (premium restaurants in three named cities), one vehicle (direct import partners, not distributors), and a differentiator built on a single-vineyard story rather than price.
Result. Staging exposed the real problem: she'd been trying to enter five markets at once with a business built for one. Cutting to two brought momentum back.
The catch
The Diamond checks coherence, it doesn't generate ideas - it tells you when the pieces don't fit but not which arena to pick. It also rewards confident answers over honest ones; teams write plausible sentences under each heading without the five actually connecting. Differentiators is usually the weakest facet, because most firms can't name one without falling back to 'quality' or 'people'.
If you could swap your 'Economic Logic' for a competitor's and it would still read true, you don't have one yet.
