This report delves into the critical aspects of managing people, focusing on team dynamics and development within a workplace context. The report begins with an introduction and literature review, setting the stage for an exploration of team roles using Belbin's theory (Plant, Monitor, Coordinator, Resource Investigator, Implementer, Completer Finisher, Team Worker, Shaper, Specialists) and Tuckman's stages of team development (Forming, Storming, Norming, Performing, Adjourning). The application of these theories is illustrated through the example of Toyota's marketing and sales teams, and Amazon's cloud, highlighting communication skills, team tasks, and challenges such as role confusion. Furthermore, the report incorporates Kolb's reflection model (Concrete, Reflective, Abstract Conceptualization, Active Experimentation) to emphasize the importance of learning from past experiences for continuous improvement. The conclusion summarizes the key findings, emphasizing the significance of team development and reflection in achieving organizational goals. The report also includes an executive summary and references, providing a comprehensive analysis of team management strategies. Appendices include a personal and professional development plan and a reiteration of Kolb's model.
