Feedback from peer researchers on interview protocol

Terminology explained to informants to avoid misunderstanding

Multiple sources of data collected (interviews, site observations, reports, and websites)

Multiple informants that represent different internal functions to triangulate responses

Investigator triangulation: first individual analysis by researchers, then comparison and joint agreement

Interviewees and cases selected following a structured and purposeful sampling approach

Multiple informants respond identically on the same phenomenon

Multiple informants representing different internal functions included to triangulate responses

Investigator triangulation: involvement of two researchers to discuss and judge data and interpretations

Raw data (transcripts) were coded on different levels (open, axial, selective) to connect it with different theoretical categories

Justification of phenomenon-driven study; described the logic and criteria applied for interviewee and case selection

Contextual information is provided to build theoretical premises for the reader

Pilot interview to test interview questions and to increase generalizability of the study

Pointing out generalizability limitations

Used standardized interview protocol

Developed and continuously updated database (including, e.g. interview transcriptions, themes, codes, and memos) to ensure complete documentation of the data analysis procedure
