Yet again, Benjamin D. Wright was ahead of the wave. Qualitative or quantitative methodology? Ben advocated using both simultaneously. Now so do our authors.
Fig.1 is our authors' flowchart of their recommended research methodology, the "Mixed research process model."

Let's streamline and redraw their flowchart:

This is now seen to correspond closely to Ben's Fig. 3 in "The Road to Reason", Wright B. D. (1998) Rasch Measurement Transactions, 11:4 p. 589. Ben wrote:
"There is no contradiction or conflict between the qualitative and the quantitative. The qualitative is complex, inscrutable, unique. But to learn from it, utilize it, manipulate it, it must be made simple, obvious, general. The leap from qualitative to quantitative is based on this organizing principle. We want to leave behind the contradiction, chaos and idiosyncrasy of the impractical concrete. We want to build an artificial world based on the practical abstract."
