Systems Analysis Assignment #2
1) In class on September 24th you were split into groups and asked to jointly come up with a solution to a case study.
Hand in the group answer, documenting who the other members of your group were. It will be marked based on the number of distinct points made and how related and valid these points are to the details of the case. If you feel it will help then have your group either meet or conference online to discuss any further improvements.
If you have any additional points of your own, or you disagree with anything that the group had to say, document that these are your own points and add it at the end.
If you missed the class then you will have to answer the assigned question on your own. (8 marks)

On October 10th we will be splitting into groups of size 5 and working on the New Century Health Clinic Case Study at the end of Chapter 5. Each group will be required to produce a Context diagram identifying the relationship of the system to external systems and a Level 0 DFD reflecting top level processes.
