The only lesson i learn from "The Profit" besides whats already stated on the article is that: It takes money to make money.
If we apply the same methodology without injecting money to business it will probably fail because the profit gained from the savings in production won't be enough to cover the debt in a short term.
There was remarkable moment in one episode where the company had made a really bad deal on a long term lease. Somehow Marcus solved the problem and I immediately grabbed my notebook and leaned in...
After a commercial break you learned he solved the problem by, drumroll, buying the entire building! IIRC it was a $20Million+ purchase since it included the neighboring suites as well.
There is much to learn by watching the Profit, but that moment was just another example of a recurring theme. That money can solve a lot of problems.
