The books and articles on research methodology will illuminate your path towards the appropriate research design. Research design is the foundation of your research, which determines the quality of the inquiry and its findings in terms of reliability and validity. I recommend you to start with at least one book, which gives a general overview of accepted research methods, and continue with a few books and articles, which focus on a specific research method of your choice. I, also, recommend you to register on web platforms ResearchGate and Academia, as through these platforms you are able to download a lot of publications, which are usually available solely through the university library. Bearing in mind, that books on research methods are quite expensive and that PhD students are always short of money, I have provided the links to the web platforms, from where you can download some books and articles on research methods for free in the electronic format.

1) Saunders, Mark, Philip Lewis and Adrian Thornhill, “Research methods for Business Students” (book, 5th edition, 2009, available from Academia).

The must read book, which provides a short and clear overview of research design process, from shaping your research topic and reviewing the literature to research philosophy, strategies (or approaches), data collection and analysis techniques. Although the book is long, it is an easy reading intended for undergraduate students (and used by graduate students) with multiple examples. Furthermore, it is not necessary to read the whole book, but rather a selection of chapters, which are relevant for your research. The essential chapters, in my opinion, are: chapter 3 on reviewing the literature, chapter 4 on research philosophy and chapter 5 on research design.

2) Creswell, John W., “Qualitative Inquiry & Research Design: Choosing Among Five Approaches” (book, 3rd edition, 2013, available from Academia).

This is a classic book on qualitative research methods in sociology, which focuses on narrative, phenomenological, grounded theory, ethnographic and case studies. The highlight of the book is chapter 11, where the author describes how one and the same phenomenon is tackled by each of the five aforementioned research approaches.

3) Mason, Jennifer, “Qualitative Researching” (book, 2nd edition, 2002, available here)

While other authors distinguish between qualitative and quantitative research methods, as well as differentiate research strategies (or approaches), Mason adapts holistic and flexible way of researching. Mason suggests, that qualitative research benefits from some quantitative input and vice versa, thus, advocating for mixing methods. Instead of classifying research strategies (and approaches), Mason focuses on data collection and analysis techniques, such as interviews, observations and visual representations (photographs, videos, spatial organisation, “cognitive maps”, etc.). I find Mason’s approach and, specifically, her focus on visual representations, quite useful for planning research.

4) Mason, Jeniffer (2006) “Mixing methods in a qualitatively driven way” (article, 2006, available from SAGE Journals)

In her article Mason explains, how does qualitative research benefit from mixing methods, encouraging the researcher to think “outside the box”, build the relationships between macro theories and micro interactions and experiences, as well as extend and complement the logic of enquiry through cross-contextual comparisons. This inspiring article will support your arguments for choosing a mixed method approach.

5) Creswell, John, and Vicki L. Plano Clark, “Designing and Conducting Mixed Method Research” (ebook, 3rd edition, 2018, available from here; chapter 3 of the book is available from SAGE).

This book elaborates on the design and application of mixed methods, taking Mason’s arguments further. The authors explore the relationships between qualitative and qualitative methods, as well as the organisation of the mixed method research, introducing the notions of convergent, sequential, embedded, transformative and multiphase research design (chapter 3).

6) Charmaz, Kathy, “Constructing Grounded Theory: A Practical Guide through Qualitative Analysis” (book, 1st edition, 2006, available from here).

One of the research strategies (or approaches) within qualitative research is referred to as Grounded Theory. This is a holistic research strategy, which guides you from framing your research questions, through data collection and analysis procedures, to writing and presenting your findings. This strategy aims to develop the theory from the data and usually draws upon the array of 20-30 lengthy interviews with the actors experiencing the phenomenon in question. There are several approaches towards Grounded Theory, which are elaborated in Saunders et al. (1) and Creswell (2). Charmaz advocates for a flexible, “subjective”, approach, which reveals the multiplicity and diversity of realities experienced by the actors and, in her own terms, is somewhat “suggestive, incomplete and inconclusive”.

7) Corbin, Juliet, and Anselm Strauss, “Grounded Theory Research: Procedures, Canons, and Evaluative Criteria” (article, 1990, available from Springer Link; the book of 2015 is available here).

Corbin and Strauss represent a rigid and “objective” approach towards Grounded Theory, suggesting the frame for coding procedures culminating into the conditional matrix, which enables to identify micro and macro conditions shaping the phenomenon in question. The aforementioned article offers a sneak preview into their approach and there is, also, a book on the same topic (it is merely about Grounded Theory, rather than about qualitative research, as the title suggests).

8) Wolfswinkel, Joost F., Elfi Furtmueller and Celeste P. M. Wilderom, “Using grounded theory as a method for rigorously reviewing literature” (article, 2011, available from ResearchGate).

Almost every research (except for Grounded Theory) in contemporary academia starts with reviewing the literature. However, there is little guidance on how to conduct the review, summarise and report the findings. Wolfswinkel et al. suggest an approach, based on the Grounded Theory of Strauss & Corbin, pursuing the systematic and transparent inquiry into the published research, which builds on and extends the existing theory. I highly recommend you to go through the article before (or while) reviewing the literature, as this approach will help you to produce a rigorous and meaningful review worth of the journal publication.

9) Yin, Robert K., “Case Study Research: Design and Methods” (book, 5th edition, 2014, available from here).

One of the most popular approaches (or strategies) in planning research is case studies. It is a method of inquiry, allowing you to understand the relationships between the phenomenon and its context, as well as to use multiple data sources, collection and analysis techniques. The classic books by Yin, continuously republished and cited, will guide you through designing and conducting the case studies.

10) Flyvbjerg, Bent, “Case Study” (book chapter, 2011, available from Academia)

An exemplary case study in urban studies was conducted by Flyvbjerg and resulted into a book “Rationality and Power: Democracy in Practice” (book chapter, 2003, available from ResearchGate), where the author examines the Aalborg city planning initiative and interprets it as a metaphor of modernity. In his short article on case studies Flyvbjerg debunks the misunderstandings about case studies and argues, that the case study approach is useful for “generating and testing hypothesis”, and, also, may drive the development of scientific theories, as in the case of famous experiment with the falling coin and feather inside the vacuum tube.

11) Coghlan, David, and Teresa Brannick, “Doing Action Research in Your Organisation” (book, 2nd edition, 2005, available from here).

If you are planning to research the domain of community engagement (aka public participation, civic involvement, etc.), then I recommend you to consider the action research, also, referred to as “live case study”. It is a research approach, where researcher works in collaboration with other actors, pursuing to change current practices. If you are unsure about the relevance of action research to your topic or do not feel like reading the whole book, then you may go through a short article on the same topic by Coughlan, Paul, and David Coghlan, “Action Research for Operations Management” (article, 2002, available from ResearchGate).

12) Groat, Linda, and David Wang, “Architectural Research Methods” (book, 2nd edition, 2013, available from here).

The last, but not least, the book, which explores research methods, specific to the domain of architecture. It includes chapters on qualitative research and case studies, as well as on quasi-experiments and simulations.

Wishing you an insight rich PhD journey!
