The research process: The research process Research paradigm
Positivist
Interpretivist
critical Research purpose
Theory building
Theory testing
Theory refinement
‘Paradigm wars’: ‘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
3 levels of understanding of social reality (Lee 1991): 3 levels of understanding of social reality (Lee 1991) That of human actors in their natural environments
That of the researcher trying to interpret what is happening
Researcher’s conceptualisation – the general theoretical significance of the observations
Case studies: 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 andamp; analysis? (Stake)
Case studies: Case studies An in-depth study of a few people, events or organisations
According to Yin (1994:14) 'need not always include direct, detailed observations as a source of evidence'
Qualitative data, analysed qualitatively
Fieldwork notes, videos, interviews, documents, researcher’s notes
Different degrees of engagement in research context
Role of the researcher
Tendency to rely solely on interviews has been noted andamp; criticised (Silverman 1998)

Plan: 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
Access: Access To the case (organisation)
Case selection
Observation andamp; document analysis
To the people
Participant selection
Access to their views andamp; actions (interview andamp; 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
Collect data: 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
Reflect: 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
