This means that generally the main point of contact will be the administrator for the component or group of components to which the module in question has been assigned during modelling. In many cases the main point of contact will not be able to provide information on every aspect of the relevant module. In such cases it is useful to include one or more additional persons in the interview. A schedule, possibly including alternative dates, should be prepared to cover the interviews with the system administrators, administrators and other contact persons. Depending on the size of the project team, tasks should be allocated between different teams of interviewers.
Experience shows that working in two-man teams works very well.
Here one person writes down the answers and comments on them while the other is asking the necessary questions. Once all the necessary preliminary work has been completed, the actual survey can begin on the previously agreed dates. This entails working through the safeguards contained in the module for which the person being interviewed is responsible in sequence. Reading out the text of the recommendations contained in a given safeguard during the interview is not recommended as the manual was not designed for this purpose. Hence, the interviewer needs to be familiar with the contents of the module.
