Games are magic at building up knowhow.

Ethan Mollick has done a lot of research about this, for example in this old Ted Talk.

Accelerated expertise is a way of abducting playable games based on experts' intuition to help learners build knowhow in a given space much more quickly.

Most games have to have "fun" as a primary use case, and "learning" as at most a secondary use case to be viable. But games in the work context that people must play (e.g. the excellent simulations by BTS) can flip it and have the learning be the primary use case and the fun be the secondary use case.

The reason games are so hyper effective is because they require the participants to be active.

Instead of being able to passively watch a situation, they are called upon to make active decisions.

To take actions means they have to be engaged and have a mental model of the situation.

Building a robust, useful mental model is what builds knowhow.

So games create knowhow as a kind of byproduct, and that byproduct can be intentionally created and harnessed in organizations by creating games.
