Problem 1
Suggest who might be stakeholders in a university student records system. Explain why it is almost inevitable that the requirements of different stakeholders will conflict in some way.
Problem 2
A software system is to be developed to manage the records of patients who enter a clinic for treatment. The records include records of all regular patient monitoring (temperature, blood pressure, etc.), treatments given, patient reactions and so on. After treatment, the records of their stay are sent to the patient’s doctor who maintains their complete medical record. Identify the principal viewpoints which might be taken into account in the specification of this system and organise these using a viewpoint hierarchy diagram.
Problem 4
The LIBSYS system has to include support for cataloguing new documents where the system catalog may be distributed across several machines. What are likely to be the most important types of non-functional requirements associated with the cataloguing facilities?
Problem 5
Using your knowledge of how an ATM is used, develop a set of use-cases that could serve as a basis for understanding the requirements for an ATM system.
Problem 6
Discuss an example of a type of system where social and political factors might strongly influence the system requirements. Explain why these factors are important in your example.
Problem 8
Why do traceability matrices become difficult to manage when there are many system requirements? Design a requirements structuring mechanism, based on viewpoints, which might help reduce the scale of this problem.
Problem 9
When emergency changes have to be made to systems, the system software may have to be modified before changes to the requirements have been approved. Suggest a process model for making these modifications that ensures that the requirements document and the system implementation do not become inconsistent.
Problem 10
Your company uses a standard analysis method that is normally applied in all requirements analyses. In your work, you find that this method cannot represent social factors that are significant in the system you are analysing. You point this out to your manager, who makes it clear that the standard should be followed. Discuss what you should do in such a situation.
