Leadership development is the process which helps expand the capacity of individuals to perform in leadership roles within organizations. Leadership roles are those that facilitate execution of an organization'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).[citation needed]
