Research Design
The research design needs
•Clear objectives derived from the research question
•To specify sources of data collection
•To consider constraints and ethical issues
•Valid reasons for your choice of design

Research Strategies: Experiment
An experiment will involve
•Definition of a theoretical hypothesis
•Selection of samples from know populations
•Random allocation of samples
•Introduction of planned intervention
•Measurement on a small number of dependent
variables
•Control of all other variables

Research Strategies: Survey
Survey: key features
•Popular in business research
•Perceived as authoritative
•Allows collection of quantitative data
•Data can be analysed quantitatively
•Samples need to be representative
•Gives the researcher independence
•Structured observation and interviews can be used

Research Strategies: Archival
research
•An archival research makes use of
administrative records and documents as the
principal source of data.
•Focus on RQ that deals with past the
changes over time.
•Primary or secondary data?

Research Strategies: Case Study
Case Study: key features
•Provides a rich understanding of a real life context
•Uses and triangulates multiple sources of data
A case study can be categorised in four ways
and based on two dimensions:
single case v. multiple case
holistic case v. embedded case
Yin (2003)

Research Strategies: Ethnography
•Ethnography is used to study groups.
•Aims to describe and explain the social world
inhabited by the researcher
•It may involve researchers living amongst
those whom they study to observe and talk
to them ion order to produce detail cultural
accounts of their shared beliefs, behaviors,
interactions, language, rituals and the events
that shape their lives.
•Takes place over an extended time period

Research Strategies
Action research: key features
•Research IN action - not ON action
•Involves practitioners in the research
•The researcher becomes part of the organisation
•Promotes change within the organisation
•Can have two distinct focii (Schein, 1999) –
the aim of the research and the needs of the sponsor

Research Strategies
Grounded theory: key features
•Theory is built through induction and deduction
•Helps to predict and explain behaviour
•Develops theory from data generated by
observations
•Is an interpretative process, not a logico-
deductive one
Based on Suddaby (2006)

Research Strategies
The role of the practitioner-researcher
Key features
•Research access is more easily available
•The researcher knows the organisation
•Has the disadvantage of familiarity
•The researcher is likely to their own assumptions
and preconceptions
•The dual role requires careful negotiation

Time Horizons
Select the appropriate time horizon
•Cross-sectional studies
•Longitudinal studies

Credibility of research findings
Important considerations
•Reliability: Consistency of findings if repeated
•Validity: research measures what you actually
intend to measure.
–Internal validity: IV is established when your research
demonstrates a causal relationship between two
variables
–External validity: Can a study’s findings be generalised
in other relevant settings or groups.
•Logic leaps and false assumptions

Credibility of research findings
Threats to Reliability
•Participant error: Any factor which adversely
alters the way in which the participant performs.
•Participant Bias: any factor which includes a false
response.
•Researcher error: Any factor which alters the
researcher's interpretation
•Researcher bias: Any factor which includes bias in
the researcher's recording of responses.

Credibility of research findings
Threats to internal validity
•Past or recent event: An event which changes participant’s
perceptions.
•Testing: The impact of testing on participant’s view or actions.
•Instrumentation: Impact of a change in a research instrument
between different stages of the research.
•Mortality: Impact of participants withdrawing form the studies.
•Maturation: Impact of outside factor that affects participants’
attitudes and behavior
•Ambiguity about causal direction: Lack of clarity about cause and
effect

Research design ethics
Remember
‘The research design should not subject the
research population to embarrassment, harm or
other material disadvantage’
Adapted from Saunders et al, (2009)
