Presentation Transcript

  1. ‘Paradigm wars’ • Paradigms reflect assumptions about knowledge and how it can be obtained • what is valid research? • which research methods are appropriate? • Positivist: reality is objectively given and can be described by measurable properties independent of the researcher • Formal propositions, hypothesis testing, generalising • Interpretivist: we can access reality through social constructions such as language, shared meanings • Rich descriptions of IS in context • Critical: social reality is historically constructed, thus the aim of research is emancipation

  2. Case studies • A research approach? (Yin) • “investigates a contemporary phenomenon within its real-life context,especially when the boundaries between the phenomenon and context are not clearly evident” (Yin 1994:13) • A method for data collection? (Galliers) • A unit of study & analysis? (Stake)

  3. Literature-based scrutiny Research themes Knowledge Literature Theory Insights Series of Conceptual frameworks Theoretical foundations Reflect Plan Analyse Collect data

  4. Plan • Plan the data collection: • What cases? • In what organisations? • Access? • Standard forms, interview protocol, equipment, recording data • Plan the analysis • What method of analysis • Forms, structure, software to help

  5. Access • To the case (organisation) • Case selection • Observation & document analysis • To the people • Participant selection • Access to their views & actions (interview & observation techniques) • “what it is to be rather than see a member of the organisation” • Participant’s opinions and stories, not analysis • Verify your understanding

  6. Collect data • Use the plan as a guide • Things will change in the field • Close interrelationship between collecting data and analysing it Analyse • Coding: concepts in the conceptual framework provide initial codes • ‘any other’ code to include unexpected outcomes • Ties the data analysis to the research themes

  7. Reflect • Deliberate and conscious thought about your research • What do these findings mean? • Implications for the conceptual framework? • Reflection either validates or revises and extends the conceptual framework • Keeps the researcher honest: • Look for disconfirming evidence • Look for alternative explanations • Review your research methods
