Nonetheless, those who have researched the use of mixed methods in business and management fields have found an increasing utilisation. This chapter explores the emergent body of literature and research that is attempting to gauge the use of mixed methods across a variety of business and management fields,. This will be followed by the presentation of findings into the research designs and methods utilised in Doctor of Business Administration (DBA) theses from the International Centre for Professional Doctorates at Southern Cross University in Australia.

This exceeds the number of purely quantitative theses (32%) and purely qualitative theses (29%). Of all the DBA theses (n=186) examined, 41 % have been Australian based.
