This case study highlights the effectiveness of using a mix of qualitative and quantitative research methods in empirical research. There is a range of data collection techniques in qualitative and quantitative research methods; we selected the focus group interview technique to identify sustainable microbusiness opportunities and training needs of microentrepreneurs. We collected data by conducting 54 focus group interviews from 54 microenterprises in eight villages. These microenterprises are run by groups, and five members from each group participated in focus group interviews. We used a structured questionnaire and a moderator to gather data systematically. Statistical analyses of data, specifically factor analysis and Mann–Whitney test, provided in-depth understanding of factors which contribute to the success of microenterprises and the training needs of microentrepreneurs. Furthermore, this case discusses when it is suitable to use mixed methods and how the focus group interview technique assists in gathering both qualitative and quantitative data of research; it also discusses the use of a pilot survey to prepare a structured questionnaire and identify variables of the study, and the usefulness of skilled moderator.
