This report is a reflective analysis of a student's group work experience, focusing on the application of organisational behaviour (OB) concepts and theories. The report begins with an introduction to organisational behaviour and its relevance in group dynamics. The main body details the student's personal experience within a group project, highlighting the challenges faced, such as differing work styles and communication issues, and how these were overcome. The student discusses their role, strengths, and areas for improvement within the team, and how the team leader's skills helped. The report then delves into four key OB concepts – Gibbs reflective cycle, Vroom's Expectancy Theory, the Theory of Cognitive Dissonance, and Self-Perception Theory – and illustrates how these concepts manifested in the group setting. The student provides specific examples of how each theory helped understand and navigate the team's dynamics, motivation, and behaviours. The conclusion summarizes the key learnings from the experience, emphasizing the importance of group work for personal and skill development, and the practical application of OB theories. This report demonstrates the student's ability to reflect on their experiences and connect them to theoretical frameworks, providing valuable insights into teamwork and organisational behaviour.
