Problems and Exercises – Essentials of Systems Analysis and Design

o   
The use-case diagram shown in Figure A-1 F (attached) 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 behaviors among two use cases in the revised diagram by using include relationships.

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