"Hire a top drawer test automation engineer to lead the company in how to run QA properly - this should be a senior developer"

Trouble is, they are few and far between and PE doesnt know how to find them...they only understand money they dont understand talent. Furthermore, when they do stumble upon talent they dont know how to leave it alone and won't trust it.

PE mistakenly tends to think that they are there for more than just what they are...money.

They need to understand that they are just people with money. The same way I understand that I am just a techie that produces things.

I bought a loaf of bread today, but that doesnt make me a baker or an expert in baking or running a bakery.

Same applies to PE. Just because they buy businesses and invest in them, doesnt make them experts in whatever they buy.
