Assume that you will develop a software system for a university. The information you have about this system is described by the scenario below: I WILL BE SURE TO UPVOTE!

The system currently used by the university can only allow a Department staff to print a variety of reports about the courses and the students enrolled in them. The new system should keep this function. In addition, the new system should enable the staff of each academic department to examine the courses offered by their department, add and remove courses, and change the information about them (e.g., the maximum number of students permitted). The information of each course stored the system includes: course id, name, time, date, location, instructor's name, the maximum number of students permitted, and a short description of the course.

It should permit students to complete the following operations online:

l examine currently available courses,

l add and drop courses to and from their schedules,

l examine the courses for which they are enrolled.

The information of each student in the system includes: student id, name, major, contact information, courses he/she has selected.

The system should ensure that no student takes too many courses and that students who have any unpaid fees are not permitted to register. (Assume that a fees data store is maintained by the universitys financial office, which the registration system accesses but does not change). In either case, the system should send an email to the student and a memo.

In addition, because students can access either day or night, the new system should be available 24 hours per day, 7 days per week. Finally, most of students accessing this system are non-CS major students, so it should ensure that a student can learn how to use the system quickly and easily.

Questions

1). Assume that your customer wants to be able to

Regularly try the prototype (the software with limited functions) during software development and provide his/her feedback to you so that you can integrate his/her feedback into the prototype.

Evaluate the risk associated with every step in software development.

In this case, which software development model will you choose for this project? Why?

2) Assume that when performing the feasibility study for this project, you find that the total benefits of the project will be $160000, and the total cost will be $120000. What is the Return on Investment of this project?

3) Assume that when performing the feasibility study for this project, you find that when the new software is in use, the total benefits of the second year will be $28800. What is the Present Value for the total benefits in the second year? Assume that inflation rate is 20%.

4) Assume that when performing the feasibility study for this project, you find that when the new software is in use, the total operational cost of the third year will be $18000. What is the Present Value for the total cost in the third year? Assume that inflation rate is 20%.
