Q.1 Suppose you were asked to lead a JAD session. List 10 guidelines you would follow in playing the proper role of a JAD session leader.

A.1 Suggestions for the JAD leader may include: the JAD sessions should be off–site, the proper people should be invited to the JAD sessions, establish clear ground rules for the sessions, set and follow a clear agenda, distribute the agenda to all participants before the sessions, remain neutral on issues, make sure that everyone has the opportunity to participate, encourage people to be creative and break free of traditional ways of doing things, manage time effectively, and follow up with meeting notes.

Q.2 An interview lends itself easily to asking probing questions or asking different questions, depending on the answers provided by the interviewee. It is possible to use probing and alternative questions in a questionnaire. Discuss how you could include probing or alternative sets of questions in a questionnaire.

A. 2 One way is to ask open–ended questions to let the individual write whatever is on their mind. In this way the questionnaire can be more probing than if it had only closed–ended questions. Another method is to ask a multiple-choice question or a yes/no question, and then, depending on which answer the respondent chooses, have them branch off into a specified set of questions. Alternatively, you might create different versions of a survey instrument, for example, one for users and one for managers of users.
