Describe the application that would allow you to register for classes using the IPO model (Links to an external site.). Don't forget storage! This describes the application from the perspective of a programmer. What do you need the system to take as input, what do you need to do to that input, how would you store data related to the system, and what output will it generate.

Now consider the application as if you it existed and was doing the things that the IPO model described. Describe what this resulting system look like? Make sure to identify the components of the system, how they are linked, what the interfaces to the system are, and what the environment of the system would be.

In the previous questions, you've been thinking about the registration application from the student perspective (i.e. someone registering for courses). How would the IPO model change from a different user's perspective? E.g. room coordinator, professor, or the person that schedules courses.
