Chapter 5: Investigating the work & Brown Cow Model: ( Duy Anh Tran ) ( Updated )
Interviewing the Stakeholders:
Interviewing the stakeholders is a technique that is commonly employed, but is not without its problems. The interviewer relies on the interviewee to know and be able to verbalize all the necessary knowledge about the work. This method may work very well when people are familiar with the work, but that knowledge is often restricted to their own immediate area.
There are likely to be few people in the organization who understand enough of the business to be the sole person to describe it for you. Interviewing also requires some abstraction and communication ability on the part of the interviewee.
For this reason, it is wise to avoid relying on interviews as your sole method of gathering requirements; instead, use them in conjunction with other techniques.
Some requirements analysts draw up a questionnaire and send it to the stakeholder in advance of the interview. While this preparatory step gives some structure to the subsequent interview, we have found few stakeholders who are motivated enough, or who have time enough, to fill in a questionnaire prior to meeting the analyst.
