Cab Wheeler is a newly hired business analyst with your group. Cab has always felt that questionnaires are a waste and interviews are the best way to elicit requirements. Now that you will be doing a systems project for MegaTrucks, Inc., a national trucking firm with branches and over 2500 employees (at multiple levels of the organizational structure) in 130 cities, you want to use a questionnaire to elicit opinions about the performance of the current and proposed systems.

1) Based on what you know about Cab and MegaTrucks, give two persuasive reasons why Cab should use a survey for this study.

2) Given your careful arguments, Cab has agreed to use a questionnaire but strongly urges that all questions be open-ended so as not to constrain the respondents. In a paragraph, persuade Cab that closed questions are useful as well. Be sure to point out tradeoffs involved with each question type.

3) Under what conditions would it be appropriate to supplement the survey with some interviews? (Identify at least 2 such conditions)
