1 Interpretive case studies Analysis Generalisations 3rd hour: Master project INF 5220, October 18th 2006 Margunn Aanestad
2 Interpretive case studies In-depth, longitudinal study of one event/organisation/process a case Investigates a phenomena in its real-life context (Yin, 1994) Case studies are common in the interpretive tradition focus on human interpretation and meaning. (Human behaviour and the reasons behind it) Interviews: main data source Cases using ethnographic methods vs. traditional cases.
3 Walsham (2002): Walsham (2002) Interpretive case studies in IS Philosophical basis of interpretative studies shared with ethnography: Status of data The importance of thick descriptions Not reporting facts, but one s interpretations of other people s interpretations Not aiming to produce truth or social laws, but still generalizable findings
4 Walsham (2002) Three ways to use theory: 1. As an initial guide to design and data collection (Build on previous knowledge, theory as sensitizing device ) 2. As part of an iterative process of data collection and analysis (Initial theories being expanded, revised or abandoned 3. As a final product of the research
5 Example 1 Walsham (1995) used Pettigrew s content, context and process framework to look at IS strategy/implementation Research questions generated: What IS strategic approaches had the organization adopted? (content) What was the position of this organization in its sector and country? (context) How had the organization tried to implement its stated strategy and with what success? (process)
6 Example 2: Structuration Theory (See Giddens also Walsham 1993): Three dimensions of meaning, norms and power Structures are produced or reproduced in action Emphasis also on unintended consequences of intentional action
7 Example 2 Theoretical guidance to formulation of interview questions: What do you understand this technology is aimed to do? (meaning) Does this technology require you to do your job in a different way? (norms) Who has required you to use this technology and what are their motives? (power) What changes in your work, and that of others in the organization, has resulted from the use of this technology? (production). What has stayed the same? (reproduction) Did any unexpected things occur in the use of the technology? And what happened as a consequence? (unintended consequences)
8 Walsham and Sahay (1999) Example of interpretive case study Walsham and Sahay: GIS in India. From a Specical Issue of MISQ on Intensive Research Longitudinal study: 3 years ( ) + historical reconstruction ( ). 5 field trips, interviews as main data source (note details given), but also systems demonstrations, archival data, informal contact, workshop. Describes gaining access, working with data, the role as researchers (p ).
9 Role of theory Walsham and Sahay (1999) The theoretical basis of our study evolved over time in response to both our deepened understanding gained through the collection of the field data and our changing ideas concerning appropriate theory.. (p. 41) Initially: Structuration theory + social construction of technology (SCOT), then (used in this paper): actor-network theory
10 Walsham and Sahay (1999) Implications for GIS practice Research questions: p. 40 Has GIS been implemented successfully for real application in district-level administraion? If not, why is this the case? What can be done about it? Page 55 onwards seeks to answer the third research question Formulated for different levels: For GIS implementation at district-level in India Potential relevance for GIS for decentralized management in other developing countries General implications for GIS practice
11 Walsham and Sahay (1999) Implications for Intensive IS Research Reflections on how to conduct and write intensive research studies (or interpretive case studies) Three criteria for convincing texts: Authenticity Plausibility Criticality Discusses also the way the paper evolved (two different versions) (More in-depth discussion of these aspect next time)
12 Analysis Walsham and Sahay (1999) Hidden process in most accounts of research Ongoing process, not just after data collection. Analytic writing, try out forms/representations of your data Geoff Walsham: In addition to field notes, I normally write a personal comment on the interview and the interviewee. I also generate sets of initial themes from my field notes as a basis for reflection, theorising, and interaction with my coresearchers (if any) See table 3 in Walsham and Sahay sets of themes that emerged after interviews during field visits
13 Silverman (2005), p. 153 Ask key questions about your data What are the main units in your data and how do they relate to one another? Which categories are used by the people you study? What are the contexts and consequences of your subjects use of categories? Do your own experiences in the field provide you with other research topics?
14 Silverman (2005) p From coding to interpretation Data reduction: Selecting, focusing, simplifying, abstracting and transforming raw data. Data display: Organized assembly of information that permits conclusions drawing Conclusion drawing/verification: Beginning to decide what things means, noting regularities, patterns, explanations, possible configurations, causal flows and propositions Testing the provisional conclusions for their plausibility, their sturdiness, their confirmability
15 Walsham on analysis: Best tool for analysis is your own mind and that of others So read your data carefully and then read it again Make data/theory links Try your ideas on others through working papers, conversations, seminars
16 Analysis Data-driven versus theory-driven analysis Data-driven: Silverman s examples in chapter 11 and 12, close to grounded theory. Theory-driven: when a case study is (re)- interpreted according to a theoretical framework: Walsham and Sahay (ANT) Hanseth et al. Reflexive Standardisation (Complexity Theory/ANT)
17 Theorizing from data Silverman (2005) p.105 How to theorize about data: Resist the temptation to rush to explanations, don t begin with Why questions. Ask what and how. Look at timings of peoples behaviour/actions or at processes of change Look at the context of your data Compare with other relevant data (or divide your data into different sets and compare them) Think of implications, how findings are related to broader categories Explore relations between models, theories.
19 On generalizability: Silverman (2005) p.136 Generalizability is (a) word that should be reserved for surveys only. What can be analyzed instead is how the researcher demonstrates that the analysis relates to things beyond the material at hand. extrapolation better captures thte typical procedure in qualitative research (Alaatusaari, 1995, cited in Silverman, p. 136)
20 On generalizability: Silverman (2005) p.108 Howard Becker: Tricks of the Trade. How to think about your research while you re doing it, University of Chicago Press, Advice when you try to generalize: Tell me what you ve found out, but without using any of the identifying characteristics of the actual case.
21 Walsham (2002) Generalizations Explanations are not predictions Four types of generalizations: Development of concepts Generation of theory Drawing of specific implications Contribution of rich insights Some examples of the types (used by Walsham):
22 Walsham (2002) 1) Development of Concepts Zuboff (1988) - concept of informate Walsham (2004) - concept of knowledge communities: are a complex network of sense-readers and sense-givers, taking action, reflecting on it, making representations based on their tacit knowing, reading others representations, and taking further action in turn
23 Walsham (2002) 2) Generation of Theory Theories of organizational consequences of IT Orlikowski and Robey (1991) Jones and Nandhakumar (1993) Walsham (2004): A basic model of communication with a sociological complement
24 Walsham (2002) 3) Drawing of Specific Implications Relationship between design and development and business strategy - Walsham and Waema (1994) Walsham (2004): on incentives and disincentives for knowledge sharing ; on forms of representation etc.
25 4) Contribution of Rich Insight Walsham (2002) Suchman (1987) - limits of machine intelligence; differences between plans and practical actions Walsham (2004) - weaknesses of the knowledge as object literature; deep meaning of tacit knowledge
26 Group discussions Three papers: Markus Bardram and Bossen Walsham and Sahay 1. Do you see traces of the analysis process? 2. What kind(s) of generalisations made? 3. What is the level of ambition for the generalisations?
27 Flyvebjerg (1991) Generalizations from one case? Flyvebjerg: five common misunderstandings: Theoretical knowledge is more valuable than practical knowledge One cannot generalise from a single case The case study is most useful for generating hypotheses The case study contains a bias towards verification It is often difficult to summarize different case studies More recent text in English: Flyvebjerg, B. Five Misunderstandings about Case Study Research, Qualitative Inquiry, vol. 12, no. 2, April 2006, p
28 Flyvebjerg (1991) 1) Theoretical or practical knowledge? Cases, examples provides the type of context-dependent learning that is required for people to develop from rulebased beginners to virtouso experts. In the study of human affairs, there appears to exist only context-dependent knowledge. There does not and probably cannot exist predictive theory in social science.
29 Flyvebjerg (1991) 2) Generalize from a single case? It depends on the case and how it is chosen (Falsification finding black swans, critical cases). Carefully chosen experiments, cases and experience were also critical to the development of physics More discoveries have arisen form intense observations than from statistics applied to large groups. (Formal) generalization (as aim, ideal) is overrated as a source of scientific development, while the power of the example is underrated
30 Flyvebjerg (1991) 3) Only for generating hypothesis? Builds on previous point -> cases can also be used to test hypotheses Generalisation dependent on case selection: Atypical, extreme cases may reveal more information than representative cases More important to clarify deeper causes and their consequences than to describe the symptoms of the problem and how frequently they occur. Extreme/deviant cases, maximum variation cases, critical cases, paradigmatic cases
31 Flyvebjerg (1991) 4) Verification bias? Is there a tendency to confirm the researcher s preconceived notions? This problem is relevant for all methods Many field studies report revision of initial assumptions Geertz: The field is itself a powerful disciplinary force, assertive, demanding, even coercive.
32 Flyvebjerg (1991) 5) Cases are difficult to summarize Strong narrative element difficult to summarize into propsitions or theory. The case story is itself the result. Is summarizing and generalizing always desirable?..the value of the case study, the contextual and interpenetrating forces, is lost when one tries to sum up in large and mutually exclusive categories Payback: a sensitivity to issues that cannot be gained from theory. Summarizing can even be counter-productive to learning Rather important: keep open the case study, maintain the rich ambiguity of reality
33 Optional readings Geertz Latour Schultze Geertz and Latour: theory strongly informs account, but is invisible. Geertz: challenging functionalist anthropology with his interpretive view Latour: Actor-Network Theory ontology is the structuring device for the account Schultze: self-reflexive/confessional accounts (for next lecture)
34 Geertz (1972) Paradigmatic case: Deep Play The (illegal) Balinese tradition of cock fighting illustrates social structures: For it is only apparently cocks that are fighting there. Actually, it is men. Page 4: The Fight a description of the procedures, rules and actions (Practices) Page 6: Odd and Even Money describes the betting procedures. (Institutions) Page 7: Playing with Fire the notion of depth, Geertz argument for the social significance of these matches (Symbols)
35 Latour: Circulating Reference.. Paying close attention to the details of scientific practice Case: Amazon study, soil sampling to detect transition between rain forest and savannah What are the actions that transforms pieces of nature into scientific facts or statements? A chain of transformations Latour s general program: challenging the discourse of science showing the disjunction between accounts of praxis and the ethnographic data science in action not ready-made science.
