Notes:
Consider the following step-by-step strategy: (continued)
- Conduct your interviews (or group work sessions, such as JAD or RAD). Because you have already collected most of the pertinent facts by low-user-contact methods, you can use the interview to verify and clarify the most difficult issues and problems.
- Follow up. Use appropriate fact-finding techniques to verify facts (usually interviews or observation).
The strategy is not sacred. Although a fact-finding strategy should be developed for every pertinent phase of systems development, every project is unique. Sometimes observation and questionnaires may be inappropriate. But the idea should always be to collect as many facts as possible before using interviews.
