The secret sauce to Amazon's success is an obsessive compulsive focus on money.
This was not my experience, reflecting on about 10 years of service in AWS network engineering (both as an engineer and manager). I’m at Oracle now, which, by contrast, is orders of magnitude more focused on revenue/spend.
I left Amazon in 2012, so things may have changed since then. But in my days I was quite impressed that the goals executives were bonused on did not have the word revenue or profit. The goals were about adoption and customer satisfaction.
