WHAT IS QUALITATIVE RESEARCH? • Many attempts to define qualitative research in the social sciences and to differentiate it from quantitative research (Bryman, 1988, 2001; Hammersley, 1992; Silverman, 2001);
• No consensus on these questions, as qualitative research cannot be considered a unified set of techniques or philosophies, and has developed from a wide range of intellectual and disciplinary traditions (Mason, 2002).
PAULINO SILVA -‐ QRM -‐ 8.JUL.2015 6
WHAT IS QUALITATIVE RESEARCH?
• Qualitative research is commonly associated with certain schools that are known for developing an interpretivist sociological tradition (Mason, 2002).
PAULINO SILVA -‐ QRM -‐ 8.JUL.2015 7
WHAT IS QUALITATIVE RESEARCH?
• Anthropologists have been using qualitative research in the form of ethnography;
• Psychologists, more associated with quantitative research methods, have developed research based on content analysis and psychoanalysis;
PAULINO SILVA -‐ QRM -‐ 8.JUL.2015 8
WHAT IS QUALITATIVE RESEARCH?
• Educators have conventionally used case study methods;
• Historians have developed an approach to the use of qualitative methods in the writing of oral and life histories;
PAULINO SILVA -‐ QRM -‐ 8.JUL.2015 9
WHAT IS QUALITATIVE RESEARCH?
• Media and cultural researchers rely heavily on qualitative ways of knowing;
• Health scholars also support strongly their research on qualitative research.

Qualita9ve research is a method of inquiry employed in many different academic disciplines, tradi9onally in the social sciences, but also in market research by the business sector and further contexts including research and service demonstra9ons by the non-‐profit sectors. Qualita9ve researchers are involved in studies of almost any imaginable phenomenon, and their studies o`en require ins9tu9onal human subjects approvals "in the field”.

Qualita've research is designed to reveal a target audience’s range of behavior and the percep6ons that drive it with reference to specific topics or issues. It uses in-‐depth studies of small groups of people to guide and support the construc6on of hypotheses. The results of qualita6ve research are descrip6ve rather than predic6ve.

Qualita've research methods originated in the social and behavioral sciences: sociology, anthropology and psychology. Today, qualita6ve methods in the field of marke6ng research include in-‐depth interviews with individuals, group discussions (from two to ten par6cipants is typical); diary and journal exercises; and in-‐context observa6ons. Sessions may be conducted in person, by telephone, via videoconferencing and via the Internet.

WHAT IS QUALITATIVE RESEARCH? • It is a type of scientific research that consists of an investigation that: – Seeks answers to a question (especially if it is a Why or How question);
– Uses a predefined set of procedures to answer it; – Collects evidence; – Produces findings that were not determined in advance;
– Produces findings that are applicable beyond the immediate boundaries of the study.
PAULINO SILVA -‐ QRM -‐ 8.JUL.2015 20
QUALITATIVE VS. QUANTITATIVE
“The distinction between quantitative and qualitative methods is not entirely clear-cut, and all researchers should think very carefully about how and why they might combine any methods, whether qualitative, quantitative, or both.”
Mason (2002: 6)

PAULINO SILVA -‐ QRM -‐ 8.JUL.2015 24
FINDING A FOCUS AND KNOWING WHERE YOU STAND • Normally, it’s not very difficult to find a broad topic or area for research;
• It’s more challenging to design an effective project with a clear, relevant and intellectually worthwhile focus to explore the topic!
PAULINO SILVA -‐ QRM -‐ 8.JUL.2015 25
WHERE YOU STAND
26
WHAT YOUR RESEARCH IS ABOUT • Explain to others briefly but specifically what your research is about. – Not a over-‐general version – Not a long and detailed version of your research focus
• The middle course between the previous two;
• Be able to articulate what is the ‘essence’ of your enquiry.
PAULINO SILVA -‐ QRM -‐ 8.JUL.2015 27
FIVE ESSENTIAL TOPICS
1. The Social ‘Reality’: Your Ontological Perspective
2. Knowledge and Evidence: Your Epistemological Position
3. Your Broad Research Area 4. Your Intellectual Puzzle 5. Your Research Questions

RESEARCH QUESTIONS • Research questions will form the backbone of your research design;
• Qualitative approaches usually require formulating questions to be explored and developed in the research process, rather than hypotheses to be tested by empirical research;
• A research question is one which the research is designed to address (it is nothing to do with a question an interviewer might ask an interviewee);

RESEARCH QUESTIONS • Research questions are the formal expression of your intellectual puzzle;
• Research questions should be formulated clearly (even if changes may occur during the research process);
• Research questions can be refined during the process of research;
• Many research topics can lead to several research questions, but we need to decide which of them is the main research question.

DESIGNING QUALITATIVE RESEARCH • After formulate research questions your research is
already set on certain tracks in relation to its design and strategy because you have started to position it ontologically and epistemologically;
• Now it’s time to think about the methods to use to generate data in order to help you to answer your research questions;
• Focus your thinking about creating links between methods and research questions;
• Think strategically (for example, the interview method can be a component in a range of different methodological strategies – it is not a strategy itself).

WHICH METHODOLOGY TO USE?
45
FROM ONTOLOGY TO METHODOLOGY?
The selection of the most appropriate research methodology is dependent on the nature of the phenomenon being researched...
PAULINO SILVA -‐ QRM -‐ 8.JUL.2015 46
... IN PARTICULAR...
Ontology
• Assump1ons which the researcher holds regarding the nature of the phenomenon’s reality…
Epistemology
• … will affect the way in which knowledge can be gained about that phenomenon…
Methodology
• … and this in turn affects the process through which research can be conducted.
PAULINO SILVA -‐ QRM -‐ 8.JUL.2015 47
METHOD: WHAT IS IT?
• The word method comes from the Greek word μέθοδος (méthodos, way to come to an end).
• “a procedure, technique, or way of doing something, especially in accordance with a definite plan.”
In Dictionary.com
PAULINO SILVA -‐ QRM -‐ 8.JUL.2015 48
RESEARCH METHODS
• What are research methods?
– Research techniques that allow specific analyzes according to the methodology followed by research in which they are used.
PAULINO SILVA -‐ QRM -‐ 8.JUL.2015 49
RESEARCH METHODS
• Examples: – Interviews – Observation – Texts and documents – Audio and video
PAULINO SILVA -‐ QRM -‐ 8.JUL.2015 50
RESEARCH METHODS
• Combination of methods (examples): – Management: Interviews + Documents – Anthropology: Participant Observation + Interviews
• One single study can combine the use of all four methods;
• Any method can be used in quantitative research (but not often).
PAULINO SILVA -‐ QRM -‐ 8.JUL.2015 51
INTERVIEWS
PAULINO SILVA -‐ QRM -‐ 8.JUL.2015 52
“QUALITATIVE” INTERVIEWS
• Normally semi-‐structured or open interviews;
• Similar to normal conversations; • Researcher – interviewee / group of people; • In person, by phone, internet, video-‐conference;
• During a month, or several years; • In a small or large number.
PAULINO SILVA -‐ QRM -‐ 8.JUL.2015 53
WHY “QUALITATIVE” INTERVIEWS?
• They can be the only adequate way to give a deep response to research questions.
PAULINO SILVA -‐ QRM -‐ 8.JUL.2015 54
PREPARE THE INTERVIEW
• Think carefully about the set of questions to use (these questions can come up from other previous interviews or from other method used previously);
• Think about the best way to approach interviewees in order to obtain their permission (e-‐mail, telephone, etc.);
PAULINO SILVA -‐ QRM -‐ 8.JUL.2015 55
PREPARE THE INTERVIEW
• Think carefully the best way to approach some sensitive topics, in order to avoid interviewee retraction;
• Prepare to manage adequately the interview (in order to obtain responses to the questions previously prepared, control the recording, if it is the case, etc.).

OBSERVATION
PAULINO SILVA -‐ QRM -‐ 8.JUL.2015 63
OBSERVATION • Watch activities made by interviewees and other professionals;
• Watch social actions, behaviours, relations, etc.; • Observation is very used to try to understand other cultures;
• Can be combined with other research methods (ex: participation in meetings, observe the reaction of interviewees during an interview).
PAULINO SILVA -‐ QRM -‐ 8.JUL.2015 64
OBSERVATION (MASTER STUDENT EXAMPLE) • “Direct observation, allowed to understand how the
activities, behaviours, relationships, social activities and events held and / or communicated by observed. The observation was carried out for long periods of time, since the company under case study work by shifts, thus allowing the presence of the researcher. The reactions of respondents was collaborative. It was not observed negative behaviours. Observations notes were registered after leaving the company.”
• This observation allowed the student to be aware of what really was going on in the factory and to validate some information collected through interviews.
PAULINO SILVA -‐ QRM -‐ 8.JUL.2015 65
TEXTS AND DOCUMENTS
PAULINO SILVA -‐ QRM -‐ 8.JUL.2015 66
TEXTS AND DOCUMENTS • A method widely used in qualitative research; • Variety of documental sources: legislation, newspapers, magazines, newsletters, textbooks and other publications, mailing (physical or electronic), projects, reports, diaries, memos, historical archives, commercials, contracts, websites;
• Can be part of a wider research strategy or be the only method used (example: study dating back to a distant past).
PAULINO SILVA -‐ QRM -‐ 8.JUL.2015 67
DOCUMENTS REGISTRATION
PAULINO SILVA -‐ QRM -‐ 8.JUL.2015 68
AUDIO AND VIDEO
PAULINO SILVA -‐ QRM -‐ 8.JUL.2015 69
AUDIO AND VIDEO • Rarely used in quantitative research, mainly because of the difficulty in quantifying data generated by this method;
• Widely used in qualitative research. For example, recorded interviews are more reliable than researcher manual notes;
• It allows the review of the content, as needed; • Sometimes it is difficult to get permission for this type of method.
PAULINO SILVA -‐ QRM -‐ 8.JUL.2015 70
AUDIO AND VIDEO • Very relevant when we want to understand how individuals express themselves, either by conversation (audio recording) or by body language (video recording);
• It may not be suitable in certain places (example: manufacturing facilities with noise hinder audio recording);
• It requires great availability of time (example: transcription of recorded interviews).
PAULINO SILVA -‐ QRM -‐ 8.JUL.2015 71
AUDIO AND VIDEO • It allows more reliable information, but can constrain the professionals;
• The researcher needs to gain the trust of the professional, which may not be easy;
• There are situations when respondents refuse to recording interviews;
• It is common for respondents to explain further their positions / opinions after the recorder be turned off.
PAULINO SILVA -‐ QRM -‐ 8.JUL.2015 72
METHOD TRIANGULATION
• Sometimes different methods are part of the same research strategy;
• It is common to use several different methods, namely, interviews, texts and documents, observation, audio -‐ all of them to enable triangulation of the data collected.
PAULINO SILVA -‐ QRM -‐ 8.JUL.2015 73
WHAT IS TRIANGULATION?
• Enable to test validity of data gathered using different research methods.
PAULINO SILVA -‐ QRM -‐ 8.JUL.2015 74
WORK / DISCUSSION
• Make a SWOT Analysis of Qualitative Research Methods – Strengths – Weaknesses – Opportunities – Threats
PAULINO SILVA -‐ QRM -‐ 8.JUL.2015 75
CASE STUDIES
PAULINO SILVA -‐ QRM -‐ 8.JUL.2015 76
CASE STUDY: WHAT IS IT?
• It is an empirical inquiry that investigates a contemporary phenomenon in depth and within its real-‐life context, especially when the boundaries between phenomenon and context are nor clearly evident.
Source: Yin (2009)
PAULINO SILVA -‐ QRM -‐ 8.JUL.2015 77
TYPES OF CASE STUDIES
• Descriptive case studies; • Illustrative case studies; • Experimental case studies; • Exploratory case studies; • Explanatory case studies.
PAULINO SILVA -‐ QRM -‐ 8.JUL.2015 78
DESCRIPTIVE CASE STUDIES
• Used to describe systems, techniques and procedures followed in practice;
• Were especially popular in the 80s, when the researchers sought to obtain exhaustive descriptions of what was done in companies;
• Currently they are used, particularly by professional bodies to describe best practice adopted by the most successful companies.
PAULINO SILVA -‐ QRM -‐ 8.JUL.2015 79
ILUSTRATIVE CASE STUDIES
• They seek to illustrate practices, supposedly innovative practices, developed by companies described as excellent;
• The knowledge of these practices is very important to understand to what extent the theory and prescribed techniques are followed by companies.
PAULINO SILVA -‐ QRM -‐ 8.JUL.2015 80
EXPERIMENTAL CASE STUDIES • They are the result of techniques, procedures and practices developed conceptually by researchers in order to be applied to companies and analysed its impacts;
• Useful for studying problems in implementation and benefits of using one or more techniques;
• Widely used in the 1970's when there was the will to design sophisticated techniques, which then would not be much used in practice.
PAULINO SILVA -‐ QRM -‐ 8.JUL.2015 81
EXPLORATORY CASE STUDIES
• Allow the researcher to explore the reasons for certain practices;
• With this type of study, hypotheses are obtained to test in future studies (either through other case studies, or through other methods of research);
• Usually they represent a preliminary phase of the research.
PAULINO SILVA -‐ QRM -‐ 8.JUL.2015 82
EXPLANATORY CASE STUDIES • They intend to study and explain the existence of
certain practices; • The emphasis is in particular not in generic, unlike the
case of exploratory studies; • The existing theory is used to explain the practices
observed by the researcher; when the existing theory does not explain satisfactorily, it is necessary to modify the existing theory or develop new theories;
• For many researchers only this type of case studies allow develop the full potential of research method based on case studies.
PAULINO SILVA -‐ QRM -‐ 8.JUL.2015 83
SINGLE-CASE OR MULTIPLE-CASES? • Single-‐case is suitable when:
– The critical case in testing a well-‐formulated theory: decisive to test a well-‐formulated theory;
– An extreme case or a unique case: infrequent or unique situation;
– Representative or typical case: context and characteristics of a day-‐to-‐day situation;
– An revelatory case: phenomenon previously inaccessible;
– An longitudinal case: studying the same single case at two or more different points in time.

QUALITATIVE RESEARCH ANALYSIS • Qualitative research provides rich, detailed and contextualized information (this normally does not happen with quantitative research);
• Qualitative research is less structured that quantitative research;
• The ‘qualitative researcher’ should master, not statistical techniques (as the quantitative researcher), but the analysis of evidence, following procedures in order to articulate them with the theory adopted in the study.
PAULINO SILVA -‐ QRM -‐ 8.JUL.2015 96
QUALITATIVE RESEARCH ANALYSIS
• The procedures of quantitative research are based essencially in statistical analysis, they are sequencial and well defined – conversely, the procedures of qualitative research are interactive, and sometimes as a result of the researcher criativity.

QUALITATIVE RESEARCH SHOULD... • Be systematically and rigorously conducted (no
excuses for doing different); • Be accountable for its quality and its claims; • Be flexible and contextual, strategically conducted; • Involve critical self-‐scrutiny by the researcher, or
active reflexivity; • Produce explanations or arguments, not presenting
only mere descriptions; • Produce explanations or arguments that can
demonstrate some wider resonance; • Not be seen as opposite to quantitative research.
