Simple Scenario

• At the beginning of each semester, students get a course catalogue containing a list of course offerings for the semester. Information about each course, such as professor, department, and prerequisites will be included to help students make informed decisions.

• The system will allow students to select four course offerings for the coming semester. In addition, each student will indicate two alternative choices in case the student cannot be assigned to a primary selection.

• Course offerings will have a maximum of ten students and a minimum of three students. A course offering with fewer than three students will be cancelled.

Once the registration process is completed for a student, the registration system sends information to the billing system so the student can be billed.

• Professors must be able to access the online system to indicate which courses they will be teaching. They will also need to see which students signed up for their course offerings.

• For each semester, there is a period of time that students can change their schedule.

Students must be able to access the system during this time to add or drop courses Using the case study in the assignment consider the following scenario:

On the first day of registration, some students face difficulty accessing the system, draw Cause-and-effect diagram for this problem.

Consider only the following four main areas: the system's hardware, the user's hardware and software and the user's training.
