SYSTEM ANALYSIS AND DESIGN2
Task 1. Requirements Elicitations:
Interview: Interview information gathering technique can be referred to as the formal
meeting that is conducted face-to-face between the interviewee and interviewer. The interviewee
is the staff or any other type of user of the system and the interviewer is the analyst. The
interview is considered as the primary method of information collection. The interview should be
conducted by an expert analyst otherwise the collected data will not be effective for project
development (Granhag et al. 2015). The interview is done on a specific place such as project
team working area or office premise. The time of conducting the interview is also predefined.
The analyst create a set of questions that are asked to the interviewer but the conversation is not
limited to those questions.
The advantages of interview are getting better insight user perspective, arranging session
easily with a person and providing more value to a stakeholder. The interview is done face-to-
face with the participant. This allows the analyst to freely communicate with the participant. The
analyst can ask various questions that are associated with the main question analyst had prepared
before interview. In a one to one interview, the participant feels more valuable as everything
he/she says is considered significant data.
The disadvantages of interview are high time consumption and missing out ideas of
various stakeholders. The interview process is very time consuming and it focuses only one or
two people of a single stakeholder category. The quality of information may be high but the
amount is very low. Therefore, it becomes of the most costly information gathering technique of
all.
