Well well well. Can’t wait to dig in.

“… we noticed that highly talented business performers are very similar to each other. (…) This led us to realise that business itself is an orderly closed system of relations between principles, and that so-called intuitive experts in business have an implicit grasp of this.”

Oh my god. “This research led to a standardised instrument for measuring business expertise among a stage-like continuum (…) these instruments have proven to be extremely reliable predictors of expertise for both executives and executive teams.”

These sorts of interventions shouldn't be possible. tl;dr DiBello and her team prevented a CEO coup by showing that he had capabilities the rest of the exec team didn't.

(Page shots continued). The implications are ridiculous:
1. There is an expert mental model of business that is common across industries.
2. So DiBello and team can test expertise levels.
3. And they can design training programs that compress acquisition of such expertise.

The paper does not reveal what that mental model is!

FWIW, I've mentioned DiBello here before:

“Business is a bounded domain like chess … but instead of four corners on the board, business has three corners: capital, supply and demand. The best businesspeople are able to model how changes in each corner related to the others.”

I mean, the field DiBello belongs to (NDM) specialises in extracting tacit mental models of expertise, and she's built her entire career consulting for companies, developing this method of training over 20 years. So I find her believable.
But she doesn't seem to have published?

Does anyone tweet about NDM?
Seems like it could be the next “mental models” fad (not necessarily a bad thing)

There’s also , but he does it more from a resilience engineering perspective. There are many researchers on Twitter, but they’re not active it seems. I think I’m the only one beating the drum right now.

Sorry that’s inaccurate. I mean I FEEL like I’m the only person iterating on messaging of NDM on Twitter. I’m sure there are others?
Whichever way it is, I feel strongly that more people should learn about it. The ability to extract tacit mental models of expertise is huge!
Agree that tacit knowledge is not talked about enough!
Furthermore, NDM and DiBello have many “big if true” statements like
- business is a closed domain
- business can be reduced to 3 dimensions: supply, demand, and capital

Have you read about Tacit Knowledge by @SamoBurja and Process Knowlege by @danwwang ?
