The Tasks
1. Explain your choice of the three most useful investigation techniques that you have used to investigate the new automated information system, TNS and the reasons for choosing them.
2. After you have analysed your collected information from TNS, produce the following UML diagrams for TNS as the specifications for a new automated information system, Tracksuit-N-Sportwear Information System (TNSIS).
A. Use Case Diagram -
• With all the critical use cases in the entire system
B. Domain Model Class Diagram -
• With all important classes needed in the entire system
C. An Activity Diagram -
• Assume that a clerk is an actor using the new system for retrieving an existing customer. The system helps the clerk to locate an existing customer. With information of the located existing customer, the clerk will place a new sale order for the existing customer. Use swimlanes as an actor (Clerk) and a system class object to show the above system work flows.
D. A System Sequence Diagram -
• Assume that a purchasing personnel is an actor using the new system for printing a purchase order. Show this specific system process in a system sequence diagram.
Note that when developing each diagram, you may make some assumptions which will affect the results of your presented modelling diagram. For examples,
o When analysing an organization's business processes, there are usually some issues which need to be clarified before you can proceed, particularly when the issues affect the way you developed your models.
o In practice you would simply ask the users. In this case you should make reasonable assumptions of what you believe the users would advise you and list those assumptions here
Right after a presented diagram, explain each diagram to your readers and your assumptions made in modelling it.
