Research methodology is something that we must follow when conducting research studies. Without a research methodology, we just search for something and if we find it, we do not know if this finding is universal, true, or even if it really exists…
In my early works, I got really interested in empirical software engineering, in particular in experimentation. One of the authors of this article was one of my supervisors and I fell for his way of understanding and describing software engineering – as an applied area of research.
Over time, I realized that experimentation is great, but it is still not 100% what I wanted. I understood that I would like to see more collaboration with software engineers in the industry, those who make their living by programming, architecting, testing, modifying the code. I did a study at one of the vehicle manufacturers in Sweden, where I studied the complexity of the entire car project. There I understood that software engineering needs to be studies and practices in the industry. Academia is the place where we shape young minds, where we can gather multiple companies to share their experiences, and where we can make findings from individual cases into universal laws.
In this article, the authors discuss research methodologies applicable for industrial, or industry-close research. They discuss even one of the technology transfer models as a way of research co-production and co-validation.
The authors conclude this great overview in the following way (from the conclusions):
When it comes to differences, the three methodologies differ in their primary objective: DSM on acquiring design knowledge through the design of artifacts, AR on change in socio-technical systems, and TTRM on the transfer of research to industry. The primary objective of one methodology may be a secondary objective in another. Thus, the differences between them are more in their focus than in which activities they include.
In our analysis and comparison of their feasibility for industry–academia collaboration in software engineering research, the selection depends on the primary objective and scope of the research (RQ3). We, therefore, advice researchers to consider the objectives of their software engineering research endeavor and select an appropriate methodological frame accordingly. Furthermore, we recommend studying different sources of information concerning, in particular, the chosen research methodology to better understand the methodology before using it when conducting industry–academia collaborative research.
I will include this article as mandatory reading in my AR Ph.D. course in the future.
