Leadership development expands the capacity of individuals to perform in leadership roles within organizations. Leadership roles are those that facilitate execution of a company’s strategy through building alignment, winning mindshare and growing the capabilities of others. Leadership roles may be formal, with the corresponding authority to make decisions and take responsibility, or they may be informal roles with little official authority (e.g., a member of a team who influences team engagement, purpose and direction; a lateral peer who must listen and negotiate through influence).Leadership development is thought to be key to business success. A study by the Center for Creative Leadership holds that 65 percent of companies with mature leadership development programs drove improved business results as compared to 6 percent of companies without such a program. Similarly, 86% of companies with leadership development programs responded rapidly to changing market conditions whereas only 52% of companies with immature programs were able to do so.
