I find it interesting that your graph leaves out any mention of innovation or invention.

It also ignores corporate cultures.

Backend engineering for a web startup is very different to backend engineering for a Wall St HFT house. I wouldn't expect someone who worked in one to be expert in the other.

Even within the web startup world, fullstack with MEAN is very different to fullstack with PHP/Apache/MySQL - not just technically, but culturally.

So I think what you have is one of those toy models that management love so much.

I'd like to see some hard big-sample-size evidence that it really does improve hiring outcomes in practice.

(1) Surely culture and technology stack are reasonably independent of the dimensions considered here (2) Wouldn't you agree that this asks an important question which is currently absent from the hiring conversation? (3) Even if the spider plot is an imperfect representation, isn't it a helpful starting point for a conversation between a potential employer and employee? (4) I'm not sure what your concern is about toy models and management. All models are toy models, the only thing which matters is whether they lead you to ask the right questions.
