Appendix A

1. The use-case diagram shown in Figure A-1 captures the Student billing function but does not contain any function for accepting tuition payment from students. Revise the diagram to capture this functionality. Also, express some common behavior among two use cases in the revised diagram by using “include” relationships.

Answer:

This relationship model needs to build up in the following manner: 1. Student to the billing counter 2. Billing counter to the acceptation of registration 3. Registration to verification of subjects and courses 4. Validate whether the student has completed prescribed courses 5. Approval from the respective course coordinators 6. Final billing made on the student to make payment of his fees.
In this entire process one has to understand what the needs of the student are and then we need to bill him as per the requirements of the course which he is bound to enroll. There should not be blind system of billing everybody without any purpose. Hence in this case the validation of subjects and needs has to be clarified at all instances.

Appendix B

1. When should you use an Agile method, and when should you use an engineering-based method for developing a system? Support your answer

Agile methods are adaptive in nature. Their nature is to welcome and adapt changes. And also the agile processes focus on people rather than process so in a case where a system to be developed is about to change rapidly and also depended upon the persons; the agile methods must be a good approach. Also the documentation part is too less in this case.
Engineering processes are predictive in nature and they do not support changes and also they are process focused. So when there is a system that will remain stable for a long period of time engineering approach is good
