After completing the interviews I decided to review the outputs to date and decided that it is necessary to add an additional interview but with much more detailed questions. The reason for this is that there is a need for some more in depth data regarding the use of the SID system by a key user and manager of the system.

I decided to ask the assistant Registry manager a series of carefully refined questions. The questions stemmed directly from previous participant answers and followed the Convergent Interviewing practice of reviewing the output of a series of questions and answers and then generating additional questions.

From the first question set I drafted a further five questions each with a few supplemental questions. The final question set contained 29 questions so the process moved from being semi-structured to structured.

The aim of the final question set was to allow for the participant to provide some very specific answers regarding the system in use.
