As Human Resource Development (HRD) research has developed, a growing variety of quantitative and qualitative data collection procedures and analysis techniques have been adopted; research designs now include mono, multiple and mixed methods. This Handbook brings together the wealth of research methods experience gained by HRD researchers into one essential volume. Organised into four parts, the book explores conceptual issues, qualitative research methods, quantitative research methods and methodological challenges. It utilises the wealth of research experiences of leading HRD scholars to provide a range of insights highlighting what works, what does not work and associated challenges. Each chapter provides annotated further reading, allowing the reader to expand on the topics discussed.
