Qualitative Methods
Dept. of Information Systems Doctoral Program in
IS ND

  • Differ from Quantitative methods in that the data
    used is not numerical measures but words the
    goal is often not to prove relationships but to
    derive arguments that relationships exist
  • Rely on interpretation
  • Such methods do not depend on amassing large
    samples, using statistics, or computing or
    counting things, but assembling arguments,
    examples, cases, etc.

Qualitative Methods Agenda Increasing the
Quality of the Discourse
Dept. of Information Systems Doctoral Program in
IS ND

  • One of the goals is to increase our knowledge of
    the world through an indirect means by
    increasing the quality of the discourse that is
    essential to knowledge generation.
  • The reasoning is thus
  • Better (more, more relevant, more useful)
    knowledge requires better theories. These
    theories arise from the crucible of discussion,
    debate and discourse. Improving the raw material
    of this discourse means improving the process of
    creating theories theories arise from our
    experiences, which are socially constructed.

The Flow
Dept. of Information Systems Doctoral Program in
IS ND

Ideas arise from researchers and others
experiences. The key is to have useful
experiences. The resultant ideas are said to be
ground- ed in these experiences. We collect
case examples of the concepts and thoughts we
want to think about in or- der to express these
thoughts better. At this stage what we want is a
wide variety of experiences to be able to
ex- press ourselves better.

The Flow
Dept. of Information Systems Doctoral Program in
IS ND

At this stage What we desire is to have
mean- ingful dis- cussions that produce robust
argu- ments.
We do this by (1) exposing the ideas to
the strongest non- superficial tests we can
find. (2) Structuring the debate to cover as
much as possible.

Testing of Theories

Correspondence
to Reality
Only when we have strong ideas with reasonable
argu- ments can we begin to pro- pose tests of
correspondence of those ideas to the real world.
It is only at this stage that the expensive
proof procedure is worth putting into play.

Basis of Qualitative Methods
Imaginings about this or other external or
internal worlds
Dept. of Information Systems Doctoral Program in
IS ND

Comments or interpretations or translations of
this or other worlds
Positivism assumes the world as an objective
reality to be discovered, measured and thus
understood.
Actual Events
Interpretivism assumes the world is socially (or
otherwise) constructed and this must be
understood first and only later measured and
discovered
10
Challenges of Qualitative Methods
Dept. of Information Systems Doctoral Program in
IS ND
  • Data are complex, multifaceted
  • Analysis is strongly influenced by data type and,
    in fact, may be contemporaneous with data
    collection
  • Not the same as easy quantitative methods
  • The search is for meaning
  • Because the data are words, they (the data) may
    possibly speak for themselves (but not always!)

11
Where/When to Use Qualitative Methods
Dept. of Information Systems Doctoral Program in
IS ND
  • Case Studies create and expose a lot of
    qualitative data
  • Content analysis uses content (i.e., words)
  • Grounded theory, to create theory
  • Where the words of research sources can serve as
    examples, cases, or insights
  • Where the researcher must interact with the
    data to derive hypotheses or conclusions

12
Uses of Qualitative Methods
Dept. of Information Systems Doctoral Program in
IS ND
  • To determine the mental processes of users of IT
    in a variety of cultural settings
  • To understand the value of IT use or IT artefacts
    to members of different cultures
  • To understand how people fit IT into their daily
    lives in meaningful ways
  • To see what strategies people engage in to
    understand IT themselves

13
Dangers of Qualitative Data
Dept. of Information Systems Doctoral Program in
IS ND
  • Thin case studies
  • Treating words as content, expression or naïve
    theory as data
  • Drawing conclusions of a statistical nature based
    on small samples
  • Researcher-driven conclusions (i.e., interpreting
    the researcher rather than the data sources
    inner states).

14
Reliability and Validity Issues
Dept. of Information Systems Doctoral Program in
IS ND
  • Source Kirk, Jerome and Marc Miller Reliability
    and Validity in Qualitative Research. Newbury
    Park Sage, 1983.
  • What reality is being probed?
  • What does reliability mean with samples of 1?
  • What is an appropriate test of validity for
    idiosyncratic experience?
  • Different sub-disciplines face these issues
    differently

15
Reliability and Validity Issues
Dept. of Information Systems Doctoral Program in
IS ND
  • Validity is really a challenge making certain
    that you have the right name for what you are
    observing.
  • Reliability is the serious scientific problem.
  • There are three sorts of reliability
  • quixotic a single method of observation yields
    an unvarying measurement
  • diachronic observation stability through time
    (test-retest)
  • synchronic similarity of observations in same
    time period (split halves, inter-rater)

16
Meeting Reliability Challenges
Dept. of Information Systems Doctoral Program in
IS ND
  • Document your procedure
  • Tell how decisions involving the research -- and
    in particular data gathering and recording --
    were made
  • Describe how the researcher was prepared
  • Sources of reliability
  • Bias (researcher effects surface biases,
    reactivity of insiders)
  • Replication (a real problem see above strive
    for disconfirmation)
  • Specification (context, conditions of research)

17
Two Examples of Qualitative Methods
Dept. of Information Systems Doctoral Program in
IS ND
  • Narrative Analysis understanding individuals and
    their times through stories that they tell
  • The Ethnographic Method understanding people and
    their ethos through a study of their culture
  • They are similar in their goals and methods but
    focus on different aspects of people. Both face
    problems with validity and reliability and meet
    the challenge in different ways.

18
Qualitative Method Example Narrative Analysis
Dept. of Information Systems Doctoral Program in
IS ND
  • Source Catherine Kohler Riessman, Narrative
    Analysis, Newbury Park Sage, 1993
  • The analysis of stories, first-person accounts of
    personal experience talk organised around
    consequential events. A teller in a
    conversation takes a listener into a past time or
    world and recapitulates what happened then to
    make a point, often a moral one.

19
Qualitative Method Example Narrative Analysis
Dept. of Information Systems Doctoral Program in
IS ND

How people make sense of their world
  • The analysis of stories, first-person accounts of
    personal experience talk organised around
    consequential events. A teller in a conversation
    takes a listener into a past time or world and
    recapitulates what happened then to make a point,
    often a moral one.

An individuals data
The experience is real for that person
The events are important to the teller
The events behave according to a naïve physics,
sociology, etc. that tells about the teller
There is a structure to the story that is
important
The teller is aware of the audience
20
Narrative Analysis
Dept. of Information Systems Doctoral Program in
IS ND

Issues 1. Realists take issue with
correspondence with truth 2. Related to other
textual approaches such as semiotics,
hermeneutics, discourse analysis,
deconstructionism 3. Highly concerned with how
protagonists interpret things 4. Highly
subjective.

Narrative Analysis Research Model
Dept. of Information Systems Doctoral Program in

Reading(5) Retelling as the agent of the text,
reinterpretation into other frameworks Analyzing(4
) Creation of a metastory, a false
document Transcribing (3) Representation,
fixing, culling, loss of information Telling (2)
Performance, description, organisation, taking
into account cultural context, interaction,
dialogue Attending(1) Reflect, remember,
recollect into observations, choose from primary
experience
23
Narrative Analysis Technique
Dept. of Information Systems Doctoral Program in
IS ND

What is a narrative (and then what happened?)
expectations of listeners are cultural and there
are brackets there are many different kinds of
structures (not an exhaustive list, just
exhausting!) Labovs paradigms All narratives
have six elements abstract, orientation,
complicating action, evaluation, resolution,
coda. Burkes dramatismAct (what), scene
(when/where), agent (who), agency (how done),
purpose (why). Gees poetics poetic units,
stanzas, strophes, punctuation.
24
Narrative Analysis Truth
Dept. of Information Systems Doctoral Program in
IS ND

Narrative is a root metaphor (Sarbin) it is
an achievement that brings together mundane facts
and fantastic creations time and place are
incorporated. Narrative can 1. Recreate
experience via order 2. Constitute reality
telling makes things real 3. Provide plans or
ideologies to live by Narratives dont speak for
themselves they speak about the teller. We aim
not for TRUTH but for believability, enlargement
of understanding rather than control
25
Narrative Analysis Validation
Dept. of Information Systems Doctoral Program in
IS ND
  • Historical truth of narrative is NOT primary
    interest we aim for trustworthiness. There are
    four criteria
  • Persuasiveness, plausibility (subject to
    rhetorical style)
  • Correspondence to informants experience (expect
    problems as narratives are movable feasts)
  • Coherence (globalrelative to narrators goals
    localinternal structural consistency
    themalcontent)
  • Pragmatic use by others in the future (!)

26
Qualitative Method Example Ethnographic Method
Dept. of Information Systems Doctoral Program in
IS ND
  • Source Stewart, Alex, The Ethnographers Method,
    Newbury Park Sage, 1998
  • Characteristics of the method
  • 1. Participant Observation
  • 2. Holism researcher constructions society
    and the data have breadth
  • 3. Context Sensitivity comprehensive data
  • 4. Socio-cultural description (social relations)
  • 5. Theoretical Connections to Anthropology

Four Phases of Qualitative Research
Dept. of Information Systems Doctoral Program in
IS ND

Invention Getting in and Getting
Along--Finding the field Copping direction
(networking), copping a look (first
viewing), copping a taste (early episodes of
non-intrusive assessment)
Discovery Getting Data -- Collecting the
data Scoring a chance (permission), scoring the
facts (gathering data, separating data from
noise, discovering new facts)
Interpretation Getting it straight --reading
the field Checking the validity checking the
reliability (strength of the data)
Explanation Getting out and getting even --
settling accounts Splitting up (severing
relationships), splitting the take
(negotiating costs and benefits with studied
group), splitting the scene.

Grounded Theory
Dept. of Information Systems Doctoral Program in
IS ND
  • Why ground your research
  • You might want to create a new direction for
    research
  • Theory might be restricting your search
  • The reality in question might be in question!
  • This might be part of action research
  • What methods are used in Grounded Theory
  • Open coding, axial coding, selective coding
  • Where are you when you finish?
  • You have a prototheory

32
Grounded Theory-Philosophy
Dept. of Information Systems Doctoral Program in
IS ND

Meanings
Meanings are important (perhaps paramount or even
the entirety of the theory) Theory should fit the
reality it is meant to explain, i.e., be
grounded in that reality. Theory is meant to do
more than explain it is to guide action.
Reality
Action/ Intervention
33
Grounded Theory-Techniques Open Coding
Dept. of Information Systems Doctoral Program in
IS ND
  • Disaggregate data into conceptual, labeled units
  • Compare derived code labels and group them into
    larger categories
  • Avoid existing sets of labels to avoid
    contamination and counter-interpretation effects
  • You are looking for significant themes.

34
Grounded Theory-Techniques Open Coding
Dept. of Information Systems Doctoral Program in
IS ND
  • Disaggregate data into conceptual, labeled units
  • Paragraphs, sentences, phrases, fragments
  • Compare derived code labels and group them into
    larger categories
  • Categories are from the text itself
  • Avoid existing sets of labels to avoid
    contamination and counter-interpretation effects
  • You are not proving the categories validity,
    just trying to establish them.
  • You are looking for significant themes.

35
Grounded Theory-Techniques Axial Coding
Dept. of Information Systems Doctoral Program in
IS ND
  • Look for relationships among various categories
  • Rearrange this into a hierarchy and allow
    subcategories to emerge
  • Identify what is happening and why, explore the
    context for events, segregate causes and outcomes
    of campaigns, and seek co-occurrences.
  • Verify derived elements as hypotheses to be
    verified with later sources seek both positive
    as well as negative cases or episodes

Examples, counterexamples
39
Grounded Theory-Techniques Selective Coding
Dept. of Information Systems Doctoral Program in
IS ND
  • Derive the new theory based on the major
    relationships among categories
  • Constantly compare incoming data with existing
    categories and data (constant comparison)
  • Sampling note You are not seeking
    representative sampling of respondents or
    informants you are seeking broad representation
    of ideas, meanings, thoughts, and expressions to
    let them emerge. Thus rather than finding
    typical respondents, you are seeking to have as
    broad a range of respondents as possible.

Grounded Theory Example
Dept. of Information Systems Doctoral Program in
IS ND

A doctoral student is interested in what how
users of CASE (Computer Aided Software
Engineering) actually use CASE in their work.
She decides that use and meaning of use are
highly related and uses Grounded Theory to build
her theory. She begins with simple questions
asked of a few referred users questions are such
as How do you use CASE? Why do you use it
that way? How did you learn to use it like
that? Note the generality of the questions Is
she using a pre-existing theory that is being
tested?How is her initial sample located?What
does she do with the answers to the questions?
42
Grounded Theory Example (2)
Dept. of Information Systems Doctoral Program in
IS ND

After the first set of interviews, she uses open
coding to create a series of fragments such as
Took a course, Learned from my colleagues, I
just copy everyone around here, The course
wasnt very good. Then she categorized the
comments (axial coding) into a set of categories
and generated a new series of (finer) questions
about training, policy, and style. Then she
selected other users who were different from the
first set (used a different tool in a different
firm) and asked these questions of them. What is
the purpose of open coding? What is the
alternative? Why did she use fragments as
opposed to paragraphs or sentences? What else
can she do with open coded fragments?What is the
purpose of categorization?Why is she seeking
different kinds of users? What happens to
reliability?
43
Grounded Theory Example (3)
Dept. of Information Systems Doctoral Program in
IS ND

These users answers were openly coded to create
more fragments (on cards) and as the number of
cards increased, she established a table relating
the fragments (now categories) to one another in
pairs or more complicated structures. Why is
she creating a database of fragments? Why have
so many?What is the purpose of the table? What
kinds of structures is she looking for?
44
Grounded Theory Example (4)
Dept. of Information Systems Doctoral Program in
IS ND

Gradually a set of structures arose that
indicated to her the varieties of use of CASE
tools. In some cases, the use was motivated by
others in some cases the users created their own
use. But it turned out in all cases that the
uses were not the set of uses for which CASE was
intended! What kind of picture is emerging? How
can we say that is theory? Whose theory is
it?What is her major finding?Why would a more
positivist approach been more difficult?
45
Grounded Theory Example (5)
Dept. of Information Systems Doctoral Program in
IS ND

Using selective coding and constant comparison,
as the set of respondents grew (and as the number
of contrasted sources of information from the
respondents grew), she became more convinced that
the categories she derived had good reason to
exist in the causal structure she was watching
emerge. However, at no time did she try to prove
her emerging theory. Why is she constantly
comparing? What is her goal here? How does she
know how many respondents to interview?What
makes her convinced about her causal
structure?Why doesnt she use this method to
prove any theory?
46
Grounded Theory Diagnostic
Dept. of Information Systems Doctoral Program in
IS ND

Bill is attempting to discover theory about
why/how NPOs employ IS consultants. He has noted
how NPOs differ from normal businesses and has
a theory about normal business. Using this
theory, he generates a series of questions which
he asks of a few NPO managers. Based on these
answers, he creates a series of categories and
notes that the categories are very similar to
those of normal businesses. He then asks for
referrals to other NPOs and uses these categories
to see if the other NPOs are in fact similar.
When he sees they are, he starts to ask questions
of a causal nature (Do you think that X causes
you to use consultants of a certain type in a
certain way and in this way builds up a theory.

Action Research - Example
Dept. of Information Systems Doctoral Program in
IS ND

Results of research into collaborative
technologies (such as E-mail) have had
inconclusive or contradictory results. In this
study, 107 people in two NZ organisations
collaborated in twelve groups over 10 to 45 days
over email-based systems. Participants were
interviewed and their messages were analysed for
content. Consistent with a social influence
model, participants felt that the e-mail
intervention increased individual knowledge
learning about other departments and departmental
heterogeneity.

Action Research - Example (2)
Dept. of Information Systems Doctoral Program in
IS ND

Note the elements of action research (1) There
was a technological intervention that was
actually employed by working groups (2) The
groups were engaged in process improvement
tasks (3) The researcher actually provided the
mediation (I.e., was part of the system).
