Borrowed from rock climbing, the 'crux' is the hardest pitch of a climb; the advice is that if you can't do the crux, don't do the climb. In strategy, the crux is the hardest part of the challenge that is still addressable. Rumelt argues good strategy is not selected from a menu but discovered by focusing on what makes the problem hard and immersing yourself until an insight about how to get around it appears.
Origin
Richard Rumelt, from his 2022 book 'The Crux,' drawing on his own past as a rock and snow climber and on the design practice of engineers and architects.
Core principles
- 01The crux is the hardest part of the challenge that you can actually address
- 02Strategy is discovered by studying the problem, not picked from a list of common strategies
- 03Insight is not magical; it comes from immersing yourself in the nature of the problem
- 04Insight is scary because it is not guaranteed to arrive on schedule
- 05Rethinking your first diagnosis is the most important intellectual tool you have
How to run it
- 1
Ask what makes it hard
For the chosen challenge, repeatedly ask what specifically makes it difficult. This turns a vague situation into a precise obstacle.
Pro tip Rumelt's standard client question is literally 'what makes it hard?' — keep pressing until the real difficulty surfaces.
Watch out Merely understanding the world is not enough; you must understand the challenge you face and what makes it hard.

Confirm the crux is addressable
Check that the hardest part is one you can actually handle. In climbing, if you can't do the crux you fall off, so you don't take the climb.
Pro tip Practice on smaller 'boulder' versions of the crux before committing to the whole route.
Watch out Picking a crux you cannot address dooms the whole effort.

Immerse until insight comes
Steep yourself in the nature of the problem. The insight about how to get around it may come while driving, the next day, or later, but it comes from immersion.
Pro tip Reframe deliberately: ask 'is there a bigger piece of wood over there I can climb onto?' rather than clinging to your first idea.
Watch out You cannot schedule insight; wanting to innovate while refusing to study the problem deeply will not produce it.
In the wild
Tasked with adding an entrance to the Louvre without a new building that would obscure the palace, Pei focused on the competing needs and had the insight to build a transparent glass structure; realizing a flat glass top would collect dirt, he made it a pyramid so it would shed grime.
→ Focusing on what made the design hard produced the now-iconic solution.
On the Voyager (then Mariner-class) program Rumelt worked on, the team could not pin down Jupiter's position precisely enough. The insight: photograph Jupiter from halfway there against the distant stars, send the picture back, and triangulate its true position.
→ Immersing in the specific difficulty yielded a simple triangulation solution that closed the targeting gap.
Common mistakes
Picking a strategy off a list
Choosing from common 'strategies for being first' avoids the real work of studying what makes your problem hard.
Clinging to the first diagnosis
Grabbing the first floating idea in a confusing situation feels safe but may not be the best plank; rethinking is essential.
Is it for you?
Best for
Designers, engineers, and strategists facing a genuinely hard, novel problem with no off-the-shelf answer
Not ideal for
Well-understood, routine challenges where a standard playbook already works and deep immersion would be over-engineering
