Overall Research Questions
They tell you what you want to focus on and what you want to
know
They set the rough boundaries of the research: you will study
some issues in some context with some actors They are oriented towards action and process
The way they are (implicitly) formulated will determine
research strategy later on
They set the vision for the research project and helps focusingactivities

My Overall Research Questions
How does the emergence of new industrial principles take
place in expert supplier firms?
What is the place and role of expert suppliers in the automotive
supply chain? What lean production techniques are used and how are they
adopted for satisfying the needs of the organisation?
How in practice takes integrated component development
place? How are organisations and processes designed to support
integration?

Research Objective
To explain the causality between different observations or
the reasons behind a certain situation concerning the
phenomenon
To explore a vague problem or a new area of
research
To describe, i.e., observe and visualise the situation of
certain phenomena
One can distinguish between mainly three objectives orpurposes with a
research project:
The research objective does not automatically define a quantitative or
qualitative logic
PhD Seminar Series. Qualitative Research MethodologyK.E. Soderquist
8/8/2019 PhD Sem March 04
9/41
Research Objective
WHAT questions of descriptive nature in the sense how
much or how many call for a quantitative approach
WHAT questions of explanatory or exploratory nature call for
a qualitative approach
HOW questions and WHY questions call for a qualitative
approach
The research questions implicitly determine the research objective, and together
they indicate quantitative vs. qualitative research:
Qualitative research is needed when we want to come to terms with the meaning,
not the right or wrong with the phenomena under investigation

Unit of Analysis What is the Case?
It is the Research Object or unitin the real world context
that you will observe
It can be:
An individual,
A role
A group
A process
An organisational entity An organisation
Or any other definable and observable unit

Unit of Analysis Example
Units of analysis in change management research:
Change efforts (e.g., installing new technology, downsizing, a particular
restructuring, effort to change corporate culture)
Change events (e.g. a crises);
The leaders of change (i.e., the individuals that drive through "corporate
revolutions" with research focus on their personal traits, leadership
styles and leadership levers);
Sectors undergoing change (i.e., comparative studies of different
business sectors in search of similarities and specificities basically in thecontent of change)
Employees facing change and acting in change processes.

MyUnit of Analysis
Could be a component development project
Could be the supplier interface Could be the product development project
I did chose the Product Development Process in each
studied firm because studying the PDP would enableanswering all the questions (at least in theory)

Case Study Research Strategy
Selecting the Case Study Organization: Criterion Sampling
Purposive rather than random samples
Samples can evolve as research moves on
Identify theory driven criteria in order to frame the research
Inclusive or contradictory samples

Case Study Research Strategy
MyCriterion Sampling
Case Study Organisations should:
Have a good record for internally generated innovation.
Innovation has a high profile in the organization.
Have established links with research laboratories.
Have an explicit strategy for R&D and R&D driven organizationaldevelopment

Participant Observation longitudinal presence
The researcher is part of the organisation on a contractual basis and has a
contextual professional role and reporting responsibility
Direct Observation (longitudinal) presenceThe researcher is present in the organisation as an external observer
Interviews occasional visits (can be longitudinal)

The overall research questions starts broadly and are gradually
narrowed by asking sub questions and sub-sub questions
Research questions should be asked crude to managers and
experts in an exploratory phase: Pilot interviews or pilot case

Data Collection through InterviewsFrom Research Question to Interview Guide (II)
My Interview Guide (minor extract). Semi-structured, open ended
How are organisations and processes designed to support integration?
What coordination activities exist in the product development process?
When and how is manufacturing staff involved in new development projects? What are the benefits of their involvement?
What are the drawbacks?
How is coordination with customers organised?
How is coordination with suppliers organised?
What communication structures exist in the product development process? Who talks to who in the process?
What channels are used?
Frequency of communication between different players?
How does communication support coordination?

Data Collection through InterviewsBasic Interview Techniques
PhD Seminar Series. Qualitative Research MethodologyK.E. Soderquist
Not too active, not too passive - The guide serves as a tool fornavigating the interviews
Use of the critical incident technique to start out the interviewsor enter into new subjects.
It is efficient when managers have difficulties in articulating answers tospecific questions and consists of asking the interviewee to describe specificevents that have had a critical impact on the way a specific issue has beenmanaged
Use re-launch questions:
- Could you tell me more about this?
- Could you specify further?
- What are you thinking about in particular?
It is important in such cases not to give any suggestions tointerviewees
8/8/2019 PhD Sem March 04

Between Collection and AnalysisInterview (or observation) Transcripts
PhD Seminar Series. Qualitative Research MethodologyK.E. Soderquist
For serious research, tape record interviews!
Always keep supportive notes
Proceed to immediate transcript Transcript should reflect the interview at 100 percent
Ask for feed-back on transcripts
Fill in uncertainties with a second (phone) interview

Data Analysis / CodingBasics
PhD Seminar Series. Qualitative Research MethodologyK.E. Soderquist
If we talk about case research, we will have atleastmultiple interviews, possibly a mix of interviews and fieldnotes
Our analytical problem is that of analysing a mass of text
Analysis / Coding represents the operations by which dataare:
Broken down
Conceptualized,
Put back together in new ways
The objective is to build theory from data a GroundedTheory approach
8/8/2019 PhD Sem March 04
28/41
Data Analysis / CodingOpen Coding (I)
PhD Seminar Series. Qualitative Research MethodologyK.E. Soderquist
Labelling events: Consists of placing conceptual labels ondiscrete happenings, events and instances in dataData are broken down and conceptualized by taking apart an observation, asentence, a paragraph and giving each separate incident, idea or event a namethat represents a phenomenon. Incident after incident in the field notes arecompared in order to give similar events the same name -conceptuallabel- andnuance and enrich each concept.
The process involves asking questions to the data so as to identify propertiesand dimensions of the incidents
8/8/2019 PhD Sem March 04
29/41
Data Analysis / CodingOpen Coding (II)
PhD Seminar Series. Qualitative Research MethodologyK.E. Soderquist
Categorising: Consists of grouping conceptual labels intocategoriesConcepts that seem to pertain to the same phenomena are then regrouped -categorized- and given a name that should be more abstract than that givenduring labeling.
Categories have conceptual power because they are able to pull togetheraround them groups of concepts.
Practically, categorising consists of going through all concepts and askingquestions such as 'What is this concept about?' or 'Is this concept similar ordifferent from the one before or after?'
In this way, categories are discovered when concepts are compared against oneanother, and concepts become characteristic components of a category - socalled subcategories.
If a concept seems not to pertain to an already identified category, it is leftaside and might become the entry to a new category as data analysis goes on.
Categorising can be bottom-up or top-down

Data Analysis / CodingAxial Coding
PhD Seminar Series. Qualitative Research MethodologyK.E. Soderquist
Condensation of data, i.e., regrouping and linking
categories to each other
Open coding fractures the data and allows the researcher to identify
some categories, their properties and dimensions. Axial coding putsthese data back together in new ways by making connections between
categories.
The objective is to identify the core category (basically
derived from the unit of analysis) and to logically relate
other main categories to the core
The Paradigm Model structures the axial coding process

5. Identify the outcomes related to the phenomenon - predictable/intended or not (competences,
ressources, knowledge, know-how...).
CONSEQUENCES
The Paradigm
Model
1. Identify the phenomenon to be studied (activity, business process...).
PHENOMENON
2. Identify the conditions of directive nature, influencing the phenomenon (driving forces,
objectives...).
CAUSAL CONDITIONS
3. Specify the context in which the phenomenon takes place (organization, information....).
CONTEXT
4. Identify the conditions of shaping nature that intervene in carrying out and managing the iphenomenon (reactions from stakeholders, cognitive processes, continuous improvement...).

Reliability and Validity (I)
PhD Seminar Series. Qualitative Research Methodology
K.E. Soderquist
Reliability consists of demonstrating that the operations of a
study -such as the data collection procedures- can be
repeated, with the same results
It is a question of documenting the research procedure Reliability is ensured by keeping data in different forms:
- Directly taken field notes - from interviews and observations,
- Expanded typed notes made as soon as possible after the field work
(this includes comments on problems and ideas that arise during each
stage of the fieldwork and that will guide further research),
- A running record of analysis and interpretation (open coding and axial
coding).

Reliability and Validity (II)
PhD Seminar Series. Qualitative Research Methodology
K.E. Soderquist
Construct validity means establishing correct operational
measures for the concepts being studied. It is ensured
through:
- The use of multiple sources of evidence,
- The establishment of a chain of evidence,- Letting key informants review draft result reports
External validity means establishing the domain to which a
study's findings can be generalized. It is ensured through
the use of a replication logic Analytical Generalisation- Relate case findings to existing or emerging bodies of literature,part
ofwhich will have been analysed in the literature section of the thesis
