Guidelines for Conducting Mixed-methods Research: An Extension and Illustration.
In this paper, we extend the guidelines of Venkatesh et al. (2013) for mixed-methods research by identifying and
integrating variations in mixed-methods research. By considering 14 properties of mixed-methods research (e.g.,
purposes, research questions, epistemological assumptions), our guidelines demonstrate how researchers can flexibly
identify the existing variations in mixed-methods research and proceed accordingly with a study design that suits their
needs. To make the guidelines actionable for various situations and issues that researchers could encounter, we
develop a decision tree to map the flow and relationship among the design strategies. We also illustrate one possible
type of mixed-methods research in information systems in depth and discuss how to develop and validate metainferences
as the outcomes of such a study.
