Lecture note on the case study research methodology vs. the action research methodology: for MBA students

 

Highlight 4 main ideas of the case study research methodology (Robert Yin's version) and 4 main ideas of the action research method (Kurt Lewin' version) and the discuss three main research practice differences of these two research methodologies in the context of doing a 4-month part-time MBA dissertation project.

Core ideas

Here are the four main ideas of Robert Yin’s case study method:

• It studies a contemporary phenomenon in its real-life context, especially when the boundary between the phenomenon and context is not clear.cdu.eduyoutube
• It works best for “why” and “how/process” questions, rather than simple frequency or description questions.cdu.edu
• It relies on multiple sources of evidence and triangulation, so the researcher can compare interviews, documents, observations, and other data.youtubecdu.edu
• It uses a structured research design with propositions, case boundaries, and clear links between research questions, data collection, and analysis.josephho33.blogspot+1

Here are the four main ideas of Kurt Lewin’s action research:

• It is problem-centered and aimed at solving a real practical issue in a workplace or community.josephho33.blogspot+1
• It is collaborative and participatory, meaning the people affected help diagnose the problem and shape the change.scribd+1
• It follows a cycle of planning, action, observation/fact-finding, and reflection, then repeats if needed.josephho33.blogspot+1
• It is intervention-oriented, so the researcher does not stay detached but actively helps implement and evaluate change.scribd+1

Three practice differences

For a 4-month part-time MBA dissertation, the biggest practice differences are:

• Role of the researcher: Yin case study keeps the researcher mainly as an observer/analyst of an existing case, while Lewin action research makes the researcher a change participant.cdu.edu+1
• Goal of the project: Yin aims first at understanding and explanation; Lewin aims at understanding plus improvement of practice.josephho33.blogspot+1
• Time and feasibility: In 4 months, a Yin case study is often easier to scope as one bounded case with planned data collection, while Lewin’s action research needs enough time for at least one full cycle of planning, action, and reflection, which can be tight if access and stakeholder cooperation are limited.scribd+1

MBA dissertation angle

In an MBA dissertation context, Yin is usually stronger when the student wants to study a company, team, or market issue in depth without changing it, while Lewin is stronger when the student has access to an organisation willing to test a small intervention during the dissertation period. For a 4-month timetable, the safer choice is often Yin unless there is a very manageable intervention, because action research can easily expand beyond the available time.cdu.edu+2
