This convergent parallel design mixed methods case study was conducted at the Kemmy Business School, University of Limerick in a Problem-based Learning (PBL) Certificate in Management (CIM) programme consisting of ten managers. This empirical research aimed to investigate and evaluate the development of ten management skills and four PBL roles in a tutorial process using a multi-phase convergent parallel design. This paper argues that mixed methods research is an accepted addition to conventional qualitative and quantitative research. It considers pragmatism a desirable philosophical companion for mixed methods and provides a framework for designing and conducting mixed methods research. Finally, it outlines how this mixed methods design contributes to high quality research and aids the answering of research questions. This paper is a work in progress; the researcher is currently working on mixed methods data analysis, interpretation and validation.
