2 Key principles Everything is strange –Question why? –Stop and reflect Members’ point of view –Developer themselves – why do that? No a priori expectations –Non judgmental –Data analysis and changing plans continuous

3 Before the study Recruiting participants –Access –Building trust Ethical issues –Relationship between observer and observed –Recognised ethical code –Participants’ right to withdraw at any point –Informed consent - ? –Data protection and anonymity Complementary methods –Interviews –Documentation analysis

4 Structuring frameworks to guide observation - The person. Who? - The place. Where? - The thing. What? The Goetz and LeCompte (1984) framework: - Who is present? - What is their role? - What is happening? - When does the activity occur? - Where is it happening? - Why is it happening? - How is the activity organized?

5 When should I stop observing? No obvious ending. Schedules often dictate when your study ends. Otherwise, stop when you stop learning new things. –when you start to see similar patterns of behavior being repeated, or –when you have listened to all the main stakeholder groups and understand their perspectives.

6 What data to collect? (1) The following illustrative list (Crabtree, 2003, p. 53): Activity or job descriptions. Rules and procedures (etc.) said to govern particular activities. Descriptions of activities observed. Recordings of the talk taking place between parties involved in observed activities. Informal interviews with participants explaining the detail of observed activities. Diagrams of the physical layout, including the position of artifacts.

7 What data to collect? (2) The following illustrative list (Crabtree, 2003, p. 53): Photographs of artifacts (documents, diagrams, forms, computers, etc.) used in the course of observed activities. Videos of artifacts as used in the course of observed activities. Descriptions of artifacts used in the course of observed activities. Workflow diagrams showing the sequential order of tasks involved in observed activities. Process maps showing connections between activities.

8 Data recording Notes, audio, video, photographs Notes plus photographs Audio plus photographs Video

9 Comparison of the three main approaches to data recording (1) CriterionNotes plus cameraAudio plus cameraVideo EquipmentPaper, pencil, and still camera. Handheld recorder with a good microphone. Headset useful for easy transcription. Video camera – handheld or fixed. Editing, mixing, and analysis equipment needed. Flexibility of use Very flexible. Unobtrusive. Flexible. Relatively unobtrusive. Needs positioning carefully to capture relevant activity. Obtrusive. Completeness of data Only get what note taker thinks is important and can record in the time available. Visual data is missing. Notes, photographs, and sketches can augment recording but need to be coordinated with audio recording for analysis. Collects thorough and detailed data, especially if more than one camera is used, but video material needs to be coordinated for analysis.

10 Comparison of the three main approaches to data recording (2) CriterionNotes plus cameraAudio plus cameraVideo Disturbance to users Very low.Low, but microphone needs to be positioned. Medium. Camera can be difficult to ignore. Preliminary field studies and piloting with participants can help to lessen the impact. Reliability of data May be low. Relies on humans making a good record and knowing what to record. High but external noise, e.g. fans in computers, can muffle what is said. Captures detail of relevant activities, provided camera is positioned appropriately. AnalysisTranscription straightforward. Rich descriptions. Transcribing data can be onerous or a useful first step in data analysis. Critical discussions can be identified. Transcription needed for detailed analysis. Can revisit permanent original record. Critical incidents can be identified and tagged. Software tools for detailed analysis. Can revisit permanent original record.

11 Practical considerations Sifting the important from the irrelevant –In some senses nothing is irrelevant, but need to focus –Have a set of questions or themes to focus on –Refine focus as you go through. Avoiding judgment –Non-judgmental, treat everything as ‘strange’. –Treat the collaborator as the expert. –Maintaining this perspective is not easy. What am I doing here? –It is impossible to suspend who you are, your training, your experiences and your expectations. –Be aware of them and question your interpretations –Easy to feel uncertain of what you are looking for. Communicating our findings –Our collaborators had expected us to be judgmental and comparative.

12 Quality assurance Set goals –Know what your focus is Pilot study –Learn from your mistakes Member checking –Replay your observations – you may have it wrong (e.g. red bar) Triangulation –By data collection method –By analysis approach Rich descriptions –

13 Data analysis Writing ethnography –Narrative Identifying Themes –Confirming and disconfirming –Many voices –Do I have to use grounded theory? Grounded Theory –Building a theory – what does it look like? Theoretical lenses –Distributed cognition, activity theory, …?

14 Data interpretation Building theory with grounded theory – Theoretical lenses –Distributed cognition, activity theory, …?
