Case study is the observation of one or multiple
cases over a period of time to understand the dynamic present within specific instances.
Cases can be a person, group, event or situation. The observation of phenomena in
these cases and the relationship between them is examined in order to test theory
or generate theory. When beginning a case study, the definition of a research
question is important so that the research has a focus amongst the large amount
of empirical data, though not necessary. This question can be redefined as empirical
evidence is collected. Case study can use both quantitative and qualitative research
methods. These can also be combined in order to strengthen theory. When
combined, quantitative data can indicate relationships to the researcher and
qualitative data can define the rationale behind these relationships. Multiple
data collection methods can also be used to better ground the emerging theory. These
methods can also be altered as the study goes on. The ability to make
adjustments is a key part of theory building in case study. Case study is also well
suited to areas of research where existing theory is not well developed or in new
areas of research.
A case study I chose to analyze was titled Emerging opinion leaders in crowd unfollow
crisis a case study of mobile brands in Twitter by Liyang Tang and Zhiwei
Ni. The initial research question sought to explain crowd unfollow in companies’
social media accounts and whether emerging opinion leaders influence these
crowd unfollow events. Perhaps these opinion leaders were the cause when an unusually
large number of unfollows occur. Twitter was chosen as a typical representative
of social networks as it is widely used by different groups of people to express
opinions and is effective as evidence in understanding peoples’ behaviors. Then
three mobile brands’ Twitter accounts were chosen to be analyzed. This was Samsung,
Nokia, and BlackBerry. Multiple data collection steps were chosen. First
software and algorithms were used for “burst detection” or detection of a crowd
unfollow event. It was found that were three types of unfollow event: one with
long-lasting duration (Nokia had one that lasted 10 days), one with short-lived
duration (Samsung had one that lasted less than a week), and the no evident
crowd unfollow (BlackBerry). Then different monitoring units were used to
detect relationships among ex-followers. There existed some users with
significant importance in only one case. Nokia appeared to have significant opinion
leaders that influenced an unfollow, while Samsung unfollowers seemed to have
little influence on each other. It was hypothesized that Samsung’s unfollow
event might have resulted from bad rumors following a product release.
In evaluating this case study and comparing it
to the "Process of Building Theory from Case Study Research" in
Eisenhardt’s article, I found many weaknesses in the case study. First, while
Twitter was chosen for significant reasons, there were no reasons listed for
choosing the three mobile companies as cases. Eisenhardt suggests focusing on
theoretical useful cases. Second, there were multiple data collection methods,
but they focused on collecting the same data. I believe the case study could
have benefited from qualitative data and analysis of the Twitter accounts of
the opinion leaders. This could have benefited in determining why they held significant
influence. Third, the hypothesis seemed to be supported by only one case.
Cross-case patterns are important in developing theory. Eisenhardt ascertained
that emerging relationships must fit with the evidence in each case.
I also analyzed Democracy in disguise: the use of social media in reviewing the Icelandic Constitution by Bjarki Valtysson in order to better understand qualitative research. Valtysson used qualitative content analysis to scrutinize how social media was used as a participative process in the collaborative rewriting of the Icelandic Constitution. Valtysson define qualitative content analysis as “research method for the subjective interpretation of the content of text data through the systematic classification process of coding and identifying themes or patterns” (Valtysson, 53). Valtysson analyzed content to find themes in how the Constitutional Council received and treated the communication and discussion that were framed in social media. The content examined was the use of Facebook, YouTube, Flickr, Twitter in engaging citizens to participate. Valtysson did not elaborate much on her methods of the content analysis. Valtysson went into more detail describing how the affordances of YouTube, Facebook, Flickr and Twitter vary. This appears and it might be a limitation of qualitative research. It is more difficult to describe one’s observations as compared to the more deliberate steps in quantitative research. She did notice a lack of responsiveness and discussion, but it seemed difficult to explain all the observation that led to this conclusion. Valtysson used figures from Statistics Iceland, which helped to support her conclusions, but I believe this made use of quantitative methods. I think that in order to improve the article, more evidence could have been described in the detailing of exact quotes and conversations that support the observations.
