Determine System Requirements
- What do you think are the sources of the information Jim and his team collected? How do you think they collected all of that information?
- Examine PE Table 6-1. Are there any requirements or constraints that you can think of that were overlooked? List them. Create a list of functional and non-functional requirementsfor the case as part of a detailed requirements statement (see notes).
- If you were looking for alternative approaches for Petrie’s customer loyalty program, where would you look for information? Where would you start? How would you know when you were done?
- Using the web, find three customizable customer loyalty program systems being sold by vendors. Create a table like PE Table 6-2 that compares them.
- Why shouldn’t Petrie’s staff build their own unique system in-house?
HINTS: See the notes for unit 5 notes regarding functional and non-functional requirements. What is functional depends on user requirements. Non-functional requirements are all the technical, financial, security, control requirements that are essential for the system operation. Create a table with two columns (one for functional and the other for non-functional requirements) and then list all the functional and nonfunctional requirements under those two columns. You need to consider everything you did and read about the case so far and come up with functional and non-functional requirements for the new system.
