I see this model as building on Laddering or the XY problem, because it also looks for a method of falsifiability.
It’s closer to a two-sided use of Eric Ries’ Lean Startup (the more scientific version), where a crux = leap of faith assumption. I’ve called the LoFA a “leap of faith hypothesis”, and your goal is to find the data that would tell you the assumption is wrong.
The other product design thinker with a similar approach is Tom Chi who uses a conjecture → experiment → actuals → decision framework.
In all of these methods, the hard work/thinking is actually finding a crux and how to falsify it. Having an “opponent” to collaborate with may make us better at this.
Nice association.
