MILESTONE 6 – PROCESS MODELING

Activity 1 – Context DiagramThis diagram is one possible solution based on the meeting transcript in Exhibit 2.1 of Milestone 2 plus the use-case (event/response) matrix in Exhibit 6.1. Note that this solution includes flows from all major events from the use-case (event/response) matrix other than pure maintenance events. Ensure that the students label the data flows and entities correctly. Also remember that data flows are not allowed between entities.

Activity 2 – Event Decomposition Diagramften the subsystem division is somewhat arbitrary. For CTTS the division is fairly obvious since part of the system will be Internet-accessible and part will not. Students, however, may come up with and be able to justify different divisions. The Enter New Client event could be placed in either subsystem; presumably the two

subsystems will share data so that a client entered in one will be available in the other.OFor purposes of class discussion, you may want to compare this to the Use Case Diagram created in Milestone 3.
