The paper describes the architecture of the system in the context of the European research project DEWI (dependable embedded wireless infrastructure) using the concept of the DEWI Bubble and its three-tier architecture especially designed to ensure dependability and interoperability.
To ensure dependability of the data, an additional researcher (K.B).
To ensure dependability [ 10 ], an interview guide was used to ensure consistency during data collection.
Both interviewers received training in qualitative interviewing techniques to ensure dependability.
A careful description of the sampling procedure and data analyses was presented to ensure dependability.
27 An audit trail using personal memos and journaling was also maintained to ensure dependability and confirmability.
24 20% of the transcripts and coding framework will be double-coded by another experienced qualitative researcher to ensure dependability and credibility of findings.
To ensure dependability, the authors described in detail any changes in data collection and proposed ways in which changes might affect results.
Maintaining an audit trail of the interview transcripts, analytical memos and the developing themes and their relations will ensure dependability of the data.
To ensure dependability i.e. the stability of data, a thematic interview guide (Appendix A) covering different topics with the same open initial question was used to ensure that the interviews covered the same areas.
To ensure dependability and confirmability, memoing was undertaken in accordance with grounded theory method and a reflexive journal was maintained throughout the study to record the thoughts and feelings of the primary researcher.
