As a physician, we are taught that learning and education never stop - they are lifelong. I think education comes in various forms: formal, informal, and most importantly, experiential. All of this defines who we are and gives us if you will our abilities to function as leaders. I believe all of those pieces constitute formal education - it is invaluable to who we are and how well we perform.
Things that people thought not possible when they were proposed and blown off become enormously successful. There are a lot of ideas that never succeed - but we all know the crazy ideas that did - who would have thought 30 years ago that people would pay $4 for a cup of coffee - but today, we have 20,000 Starbucks stores around the world. A group of prospective investors once remarked that "Google" was the "balloon company." The point is, don't rush to pooh-pooh something you don't understand or aren't willing to try - it could be something that changes the world.
Talking about improving the culture, I prefer to say "develop" or "evolve" rather than "change". If I walk into a room and say: "we are here to change the organization," it sends shock waves through the group. If I say: "your success to date has come from who you are, to be successful in the future, we need to get to X, let's talk about how we evolve the organization to that point," that is a very different statement. Successful organizational "change" must come from the people. So, recruit them with common purpose, recognize that it will take time, and plow forward.
You frequently hear the phrase "culture eats strategy for lunch!" This is something that they don't teach you in school and few leaders appreciate. Cultural influences come at you from two different directions. There is the organizational culture that you must understand if you are to impact significant strategic initiatives. If the "people" are on board, you can achieve anything. Vice versa if they are not - you will not achieve anything.
I have participated as a leader in many organizations where the leadership culture was just mean - ugly, where competitiveness, and destructive relationships stymied progress. There should be healthy tension and candid debate, but leadership teams need to practice communication, relationship building, emotional intelligence, and be aligned around common purpose to achieve organizational success. Senior leaders, chief executive officers, others need to ensure they are fostering the right environment for leadership otherwise all of that ugliness will trickle through the organization.
Good C-suite executives rise to the top because they can execute. Good execution at the operational level requires us to have a solid handle on details - that doesn't mean operators don't delegate, it just means that they have a strong line of site to the front lines because they know that is where operational success is driven. As people move into the c-suite, they hold on to their operational persona and likely feel the need to do more. But success in the c-suite comes from our ability to be more strategic and trust that we have selected highly qualified people to take our places.
