There is never a one-size-fits-all approach to being a successful CEO - the context, both internal and external affects performance and suitability dramatically. That said, this is great research into what sets successful CEOs apart which I'd agree with. Common focus areas for our executive work are decision making, results-driven stakeholder management, adaptability and predictable consistency - all areas mentioned here which lead to success. Each individual and team will have their own starting point and preference, the key to success is knowing where you're starting from and creating your own plan to success.
Our analysis revealed that while boards often gravitate toward charismatic extroverts, introverts are slightly more likely to surpass the expectations of their boards and investors. We were also surprised to learn that virtually all CEO candidates had made material mistakes in the past, and 45% of them had had at least one major career blowup that ended a job or was extremely costly to the business. Yet more than 78% of that subgroup of candidates ultimately won the top job. We found that educational pedigree (or lack thereof) in no way correlated to performance: Only 7% of the high-performing CEOs we studied had an undergraduate Ivy League education, and 8% of them didn’t graduate from college at all. But our most important discovery was that successful chief executives tend to demonstrate four specific behaviors that prove critical to their performance.
