2016, Moscow. I was sitting in Starbucks with my new acquaintance Taraq. We were talking about the company he worked for. It happened to be one of the biggest Schlumberger subcontractors in the field of deep sea mining. They were looking for an expert in process optimization and management. I was approximately in the middle of my success story, how I had managed to turn a team of losers into rock-stars. The manufacturing line productivity was boosted by over 200% as Taraq stopped me. "Do you have any certificate that proves your qualification? 6 Sigma Black Belt or something like this?" No, I didn't have it. Although, I had read many books by this time dedicated to this topic.
