Leadership development expands individuals' capacity to perform leadership roles through building alignment, winning mindshare, and growing others' capabilities. Leadership roles can be formal or informal. Leadership development traditionally focuses on developing individuals' abilities and attitudes, but is more effective when integrated over time and involves goal-setting, assessment, and support from supervisors. Leadership can also be developed collectively by strengthening connections between leaders and aligning efforts with systems. Succession planning develops high-potential individuals for future leadership roles through international experience and alignment with organizational vision.
