Teams are required for several reasons: multiple perspectives lead to better solutions; trust and support among members promotes effectiveness; and collaboration amplifies individual talents. Effective teams are composed of committed individuals with diverse skills focused on a shared mission. Key roles include the team leader for communication and implementation, a recorder for documentation, and an advisor for process guidance. Building a successful team follows stages of forming, storming, norming, performing, and adjourning, and applies principles of defining goals, leading by example, valuing all contributions, and rewarding group achievements.
