Ch.5 Problems and Exercises
1. One of the potential problems mentioned in this chapter with gathering information requirements by observing potential system users is that people may change their behavior when observed. What could you do to overcome this potentially confounding factor in accurately determining information requirements? (Hoffer 148) Employees under observation do in fact act differently than if they were left alone. One way to circumvent the process is to watch them when they do not know they are being observed. Observing over time is another way to be unobtrusive in their environment. An employee acting natural is the key to business operations data collection success. The analyst could also develop anonymous interviews, anonymous surveys, etc to get a more accurate depiction of employee and business operations. Utilizing multiple data collections would result in more accurate data assessments.
3. Suppose you were asked to lead a JAD session. List ten guidelines you would follow in playing the proper role of a JAD session leader. (Hoffer 148) JAD sessions need to be conducted absent workplace. Attendees need to be briefed on the reasoning behind the JAD session with written agendas handed out to each one. All matters MUST be neutral in support (Do not sway one way or another). Participation is a must; each attendee needs to be proactive in the session to handle the issues at hand. Ground rules and issues will be noted during the session while managing time, efficiency, covering important details, problem solving (if able), and all personnel should be in an informal environment to make them feel comfortable.
