This causes several problems, including employees being unable to quickly locate other employees, company mailings being sent to the wrong addresses, payroll checks that cannot be delivered, paper-based company telephone books that are out of date almost as soon as they are printed, and less than ideal United Way and Savings Bonds contributions. If you have not already drawn a Context Diagram in Milestone 2, draw one now based on the meeting transcript in Exhibit 2. Upload document Create flashcards.
Students should realize that based on additional interviews they may need to revise this matrix to reflect new problems, opportunities, directives, and changes in their understanding of urgencies and priorities. Thirdly, you will draw event diagrams to model individual processes. For example, we have encountered clients who have mentioned that they envisioned expected? 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. The user clicks on detail link for an employee.
You might stress to the students that oftentimes user expectations are simply stated in terms of a new system that works! System updates data for pay rates or job title or supervisor.
Notice that the sample solution provided included several number 1 priorities. Also, state any assumptions you make. You dtudy need to build the corresponding process models. The system will display the phone number, employee’s office location, department, job title, and supervisor.
Process modeling – Chapter 9 2. Redundancy of keying employee information in both micro and mainframe. Milestonw your data model from Milestones 3 and 4 as an attribute reference. In this milestone we focus on using and constructing data flow diagrams DFDs and decomposition diagrams to perform process modeling.
System displays all employees that match criteria. The sample RSS we provide represents a more general description that the user conveyed. They may not have all the answers at this point in time. 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.
System displays option for kind of information to be displayed. For background information on each use case, see the meeting transcript in Exhibit 3. Add this document to collection s. If user then selects one employee, system displays option for kind of information to be displayed.

But some users have very specific ideas or expectations. Your e-mail Input it if you want to receive answer.
During this milestone you will first construct a context diagram to establish project scope and boundaries. Identify external and temporal business events for a system. Please email the deliverables to the TA and the instructor References: For more information on each of these use cases, see the meeting transcripts in Exhibit 3.
Users cannot get reports that they need in a timely fashion. Actor s Event or Use-Case Trigger Responses System reports all employees that match search criteria, listing phone numbers, office location, department, job title, and supervisor. You have already built the data model Milestones 4 and 5 to document business data requirements for the new system.

It is important that the students recognize that while it may appear to the students that Jack Mills initiated this project, Dotty Jones is the key user contact.
It is possible they might have identified different ones and stated completely different values for each of the cells.
