Chief Vásquez and Dr Lugo discuss the Tuckman model of team development, covering forming, storming, norming, performing, and the additional stage of adjourning. Dr Lugo explains that forming involves polite boundary-testing, storming involves conflict and power struggles, norming involves negotiation and consensus, and performing is the stage of high efficiency. He adds that adjourning occurs when a team disbands after completing its task, often leading to mixed emotions. They also discuss the role of a facilitator in guiding teams through these stages.
