You will be assessed on your ability to present the requirements in a clear and logical manner, the way you have addressed the description of the system provided, and the quality of your discussion of the issues arising.

Note that you are required to present requirements and models for the new system at Valentinos – much of the discussion below relates to the current system.

2. Develop various Project Initiation Products  You should identify an IS/IT project that Valentinos need. Develop a Project Vision statement, a Scope diagram, cost benefit analysis and a profit loss analysis for 3 years.

3. Produce a Requirements Catalogue

This should take the following form:

A list of at least 10 summary functional requirements, each characterised by a name, a short description (< 25 words), and a priority. Produce a list of 5 non-functional requirements, each including a 50 –100 words description.

Two of these functional requirements should be expanded in more detail to give a full description of the requirement and include any associated non-functional requirements such as those associated with performance, usability, and security. For an example of how this can be done see course notes –but other formats are acceptable.

4. Produce a Use Case model of the required system

Produce a Use Case Diagram (use UML standards) and a detailed description of a Use Case of your choosing (use the standard provided by Cockburn in the notes or any other recognised standard - quote the source you used).

5. Produce a Class Model of the required system

Class Model – follow UML standards. For each class include attributes (full set) and operations (samples only) for each association include a name and a multiplicity and any other constraints. In a further A4 page describe any decisions you have made in producing your model: what to include or exclude, a discussion of alternative ways of modelling that you rejected, any clarification of your model, any areas requiring further definition, any assumptions made, and how it relates to the requirements you have defined in part 3.
