Failing to gain enough support from the CEO. Without it, your chances of success drop to less than 50 percent.
Confusing a leadership strategy with a succession plan. While they are similar, your leadership strategy should be an active, business-centric plan that is owned and led by the senior-most business leaders of your company.
Lacking a clear definition of what leadership means in the context of your business strategy and organizational model. Leadership is contextual, and you need to understand those capabilities that will keep your organization competitive.
Ignoring the complementary power of the team. The value of the leadership strategy is that you look holistically at the capabilities of the business. You need to build "extreme" teams with leaders who complement each other so that you can become a powerful resource for your organization.
