GMU Why You Think that Requirements Engineering Has Proven Difficult in Practice Ques

Question Description

Instructions

Several of the questions use the scenario below. Please read carefully, and perhaps store or print separately where you can read it when answering these questions.

“You are on a team to develop an on-line system for the Marymount University graduation petition. The student will fill out an application which will be available from the Registrar’s Web page. The students use their username and password to log into the application and the system validates that the user ID is a current student and identify their major and any specialty and minor. The students enter further information when they estimate when they will be graduating. The Registrar’s Office records the information in a separate Excel file that includes which students are thought to be walking in the spring ceremony and passes on the information to the appropriate school Dean. The Dean sends it to the student’s advisor who looks at the degree plan and documents which classes are needed before graduation and send this information back to the Dean. The Dean notifies the students of their requirements and notifies the Registration Office of whether it is likely that the student will graduate at the time they indicated. The Registrar’s updates their Excel spreadsheet accordingly.”
