Thirdly, you will draw event diagrams to model individual processes. Prepared by Gary B. This is real life! During this milestone you will first construct a context diagram to establish project scope and boundaries. You now need to build the corresponding process models. The user clicks on detail link for an employee. The system displays all employees matching the criteria with links to detailed information for each employee.
If you have not already drawn a Context Diagram in Milestone 2, draw one now based on the meeting transcript in Exhibit 2. But some users have very specific ideas or expectations. Finally you will construct a system data flow diagram that shows the big picture of the system, and a primitive data flow diagram for a single event process. Brief Statements of Problem, Opportunity, or Directive 1. Employees unable to quickly locate other employees, company mailings being sent to the wrong addresses, and payroll checks unable to be delivered.
