Discuss the relative advantages of the interview, the transaction review (walkthrough), the observation, the internal literature review, and the database and files review as they might apply to each of the following situations that might occur during the systems survey:

a. Gaining an initial understanding of the system under review.

b. Confirming the understanding obtained in part a.

c. Determining the nature and extent of reported system failure (e.g., in an Order-to-Cash process, numerous customer complaints, excessive bad debt losses, abnormally high sales returns, and unusual delinquency in shipping customer orders).

d. Assessing/evaluating (1) economic feasibility, (2) operational feasibility, and (3) technical feasibility.
