This report provides an in-depth analysis of team building theories, primarily focusing on Belbin's team role theory and Tuckman's theory of group development. The introduction highlights the significance of team building skills and introduces the core concepts. The report then delves into the specifics of Belbin's theory, detailing various team roles (Action-Oriented, People-Oriented, and Thought-Oriented) and their associated strengths and weaknesses. Following this, Tuckman's theory, outlining the stages of group development (Forming, Storming, Norming, Performing, and Adjourning), is presented. The core of the report involves an analysis of team issues within a real-world context, applying both Belbin's and Tuckman's theories to identify strengths, weaknesses, and conflicts within a team. The report also suggests strategies to overcome these issues by aligning individual roles with strengths and understanding the stages of team development to foster collaboration and enhance overall team performance. The report concludes by summarizing the findings and emphasizing the importance of applying these theories for effective team building. References are provided to support the research.
