This report presents the results of a study investigating the impact of diversity on organizational performance, using Kings College Hospital as a case study. The research employed both quantitative and qualitative data collection methods, including questionnaires for 100 respondents and open-ended interviews with 10 line managers. The report details descriptive statistics of demographic variables, including age, education, and work experience, illustrating the diversity within the workforce. Key findings reveal employees' perceptions on the impact of educational background on confidence, the positive influence of a diverse workforce on innovation, and the significance of training in fostering awareness about diversity. Inferential analyses, including correlation and regression, were conducted to determine relationships between variables, revealing a positive correlation between organizational performance and diversity. The regression analysis indicated that independent variables explained 95% of the variation in the dependent variable (organizational performance). The report provides valuable insights into the dynamics of diversity within the hospital setting and its influence on various organizational aspects.
