© 2005 course technology2 University Of Palestine Activity Diagrams for Describing Business Use Cases (Cont.) Activity Diagram with Partitions: To indicate who performs each activity, you add partitions to the activity diagram. A partition is a column on an activity diagram. Each partition represents a stakeholder (business actor or worker) that carries out some activity. Position every activity in the partition of the object that performs it. Name each partition at the top of the column, according to the participating object.

During this case study, you meet with stakeholders to discuss the workflow for two business use cases. During the meeting, you draw and revise activity diagrams in order to help stakeholders work toward a consensus regarding workflow.

Problem Statement: You’ve met individually with stakeholders involved in the business use cases, Manage case and Administer payments, in order to discuss workflow for these processes. Not too surprisingly, everyone has a slightly different view of how best to sequence activities, so you decide to convene a meeting to reach a consensus. In preparation for the meeting, you plan to create activity diagrams with partitions to summarize your best understanding of the workflow for these business processes.

Business Use Case: Manage Case (Dispute) This example uses two sections found in the formal template, preconditions and postconditions. A precondition is something that must be true before the use case begins. In the following example, a Peace Committee must already have been set up before the CPP can manage a case. A postcondition is something that will be true after the use case ends.

[ A postcondition on success is something that will be true after the use case ends, but only if the goal (expressed in the name of the use case) is accomplished. In the example, the postcondition on success is that a case report has been prepared for the case being managed during the business use case]. [A postcondition on failure (not shown in the example) is a condition that will be true after the use case is over, if it ends with abandonment of the goal].

Postcondition on success (what is true after the use case completes successfully): “A case report has been prepared”.

Flow: 1.The Peace Committee in the area initiates a Peace Gathering. 2.The Peace Committee prepares an individual interview report for each party to the dispute. 3.Once all reports have been taken, the Facilitator summarizes the reports to the Peace Gathering. 4. The Facilitator verifies the facts in the reports with those present. 5.The Facilitator solicits suggestions from the gathering. 6.The Facilitator solicits a consensus for a plan of action. 7.If the gathering has decided to refer the case to the police, the Facilitator escorts the parties to the police station, after which the Convener prepares a case report as per Step 10.6

Flow (Cont.): 8.If, on the other hand, a consensus has been reached, the Facilitator appoints a Monitor. 9.The Monitor performs ongoing monitoring of the case to ensure its terms are being met. 10.When the deadline for monitoring has been reached, the ongoing monitoring immediately ends. At this time, if the conditions of the case have been met, the Convener prepares a case report. If the conditions have not been met, then the process begins again (return to Step 1.).

Business Use Case: Administer Payments Precondition (what must be true before the use case begins): A case report has been submitted. Postcondition on success(what is true after the use case completes successfully): Payments have been made to funds and to accounts of Peace Committee members involved in the case.

© 2005 course technology13 University Of Palestine Case Study D2: Business Use-Case Activity Diagram with Partitions ( Cont.) Flow: 1.The Convener reviews the case report to determine whether rules and procedures have been followed. 2.If rules and procedures have been followed: a. The Convener marks the case as payable. b. The Convener then disburses payments to the various funds and to the accounts of Peace Committee members who worked on the case. c. The existing Accounts Payable system actually applies the payments. (Constraint: The AP system must continue to be used for this purpose when the project is implemented.) 3.If the rules and procedures have not been followed, the Convener marks the case as non-payable.
