      	Establish the objective for the interview. Inform all participants of objective, time, and locations.

During interview:

	Follow up on open and unanswered questions.

Question 11: Research the topic of “scope creep”, which occurs when stakeholders request additional features and functions. How would you go about keeping a system that you are analyzing from growing and possibly including new functions that should not be part of the system? How do you avoid scope creep?

Questions 12-23: THE STATE PATROL TICKET PROCESSING SYSTEM (TPS)

Imagine that you have been asked to perform “Systems Analysis” on the following Ticket Processing System (TPS) Description and Requirements. Please carefully review:

When the trial is complete, the court sends the verdict to the ticketing system. The verdict and trial date are recorded for the ticket. If the verdict is innocent, the system that produces driving record reports for insurance companies will ignore the ticket. If the verdict is guilty, the court gives the driver another envelope with the ticket number on it for mailing in the fine.

If the driver fails to pay the fine within the required period, the ticket processing system produces a warrant request notice and sends it to the court. This happens if the driver does not return the original envelope within two weeks or does not return the court supplied envelope within two weeks of the trial date. What happens then is in the hands of the court. Sometimes the court requests that the driver’s license be suspended, and the system that processes drivers’ licenses handles the suspension.

even spelling and formatting errors, has been accounted for in this parse. Nothing should be missing from the original description. The “Statement Type” (column 3) indicates whether or not the Statement is a TPS “Requirement”. The “TPS Functionality?” (column 4) contains some observations regarding potential TPS Functionality.

No.	Statement
10		Requirement	Yes – record driver violations
20	[The purpose of the State Patrol Ticket Processing System (TPS) is to] keep records of fines paid by drivers when they plead guilty or are found guilty of moving violations by the courts,	Requirement	Yes – keep records of finds paid by drivers
30		Requirement
40		Guidance
50	Yet a third system produces driving record reports from the ticket and accident records for insurance companies	Guidance	No – separate system
60		Guidance
70		Guidance
80	State Patrol operations (what the officers do on a daily basis) are entirely separate. Our focus is the TPS.	Guidance	No
90	The portion of the database used with the TPS involves Driver Data, Ticket Data, Officer Data and Court Data.	Requirement
100		Requirement	Yes, specifies input data requirements
110		Requirement	Yes. TPS must create and maintain Ticket Data
120		Requirement	Yes, specifies data requirements
130	Ticket Data attributes include ticket number (each is unique and preprinted on each sheet of the officer’s ticket book), location, ticket type, ticket date, ticket time, plea, trial date, verdict, fine amount, and date paid. Court and officer data include the name and address of each,	Requirement

With this TPS information now in hand, please answer these questions:

Question 12: Review the original TPS word description and compare it to the “parse” provided in Table 2. Is the parse 100% accurate and complete? It must be. Or, was anything missed when translating the TPS description to the parse?(Hint: It is possible something is missing).

Question 15: Consider External and Internal Events (discussed in Session 3 / Chapter 5. Also discussed in detail in Chapter 3 of textbook). To what Events must the TPS respond? Using Table 3 (see below), please fill in the list of event(s), type of event and define a resulting use case. Use as many rows as necessary (you can add rows to the table).

Your Answer to 21:

Explanation: The driver submits the plea for claiming innocence to the TPS. Once the system receives the plea, it looks up driver, ticket, and officer information; then, sends a ticket details report to the appropriate court. A trial date questionnaire form is also produced at the same time and is mailed to the driver. The instructions on the questionnaire tell the driver to fill in convenient dates and mail the questionnaire directly to the court. Upon receiving this information, the court schedules a trial date and notifies the driver of the date and time.

If the verdict is guilty, the court gives the driver another envelope with the ticket number on it for mailing in the fine.

Consider that the “ticket” is an object that changes states over time.

Your Answer to 23	:

 Populate this MS Word file with your answers to all questions. Post your completely populated HW #2 report to the Discussion Forum by the “Interim” Due Date to support Peer Reviews. .

 Then, using this same file, perform Peer Reviews on your two (2) assigned student
assignments. Starting with your “Interim” submittal, annotate / update your report with what you learn from your Peer Reviews to turn “Interim” into “Final”. You must clearly show where you have updated your document based on your assigned reviews. It is best to turn on “Track Changes” to capture your updates. If your instructor cannot easily find your updates, it will be assume that you did not do your Peer Reviews.
