It is silly I agree but it worked for many decades, in the sense the customers are happy and engineers here seem to be happy. One can also say it didn't work because the company hasn't turned into Google or "existed" with a huge cash windfall for founders.

Of course that was just one variable and it wasn't isolated. There could have been other factors and reasons for the said result and it might not have had anything to do with "no MBAs" rules.

I just presented it as a reference or what others do as a "solution".
