Corporate diversity initiatives have neither yielded higher financial returns for companies nor created significantly greater equity and equality of outcome for socially disadvantaged groups within organisations. There has been a systematic failure of diversity initiatives, as the strategic business importance of diversity has been avoided. Researchers argue that effective diversity management is dependent upon appropriate structures and systems, not upon human resource management training alone. This article discusses the impact of the design, introduction and application of the 'Diversity Quality Cycle'. This model allows for the embedding of the values of equality of opportunity and cultural diversity throughout core business functions, and for positive long-term change. A mixedmethod approach was taken; Participative Action Research is the main methodology employed, within which quantitative data were generated, analysed and interpreted. The main case study organisation is a Further Education College in the West of England.
