By outlining the basic principles of research and tying them in with human resource development (HRD) functions, this practical guidebook describes how to apply specific research methods to common HRD problems. Topics covered include performance problem analysis, performance solutions and assessing solution adequacy. Background sections on the theoretical and research aspects of the methods are included, with examples drawn from the field showing the approach used in practice. The book concludes with a discussion of special issues including legal and ethical concerns, reporting results, sample size and statistical analysis issues, and confidentiality and privacy.
