Both quantitative and qualitative methods are important to the analysis of organization and management, and they are certainly not opposed to each other. Increasingly, researchers have called for more attention to the design of method triangulation that has the potential to enhance the reliability and validity of research findings. Given that ontology will determine epistemology, we argue that when the problems or realities demonstrate the characteristics of order-chaos dualism, a mixed method approach is most applicable. Accordingly, in this paper we attempt to develop a program for conducting such research. The program includes five steps: initiating, collecting quantitative data, determining a proper mathematical model, interpreting the complexity qualitatively, and ending the program.
