Session 4: Requirements Modeling

Overview:

The SCR Associates case study is a Web-based simulation that allows you to practice your skills in a real world environment. The firm offers IT consulting, solutions, and training. SCR plans to open a new high tech training center, and needs to develop a Training Information Management System (TIMS) to support the center. You are a newly hired systems analyst reporting to Jesse Baker, systems group manager, and will help her develop the system. The case study takes you to the SCR website, where you receive e-mail and voice mail messages from Jesse, obtain information from SCRs resource libraries, and perform various tasks. Jesse has high standards, but seems very fair. She made it clear that she expects your work to be accurate, thorough, and professional.

Before You Begin

To prepare for this work session, you should review the following topics:

System requirements

Functional decomposition diagrams

How Do I Use the Online Case Simulation?

Read the preview, and review the Chapter 1 background material if necessary.

Session 4 As you begin the requirements modeling process, you receive specific directions from your supervisor, Jesse Baker. She wants you to conduct a survey of former and prospective students, lead a JAD group session, and draft a list of system requirements based on the results of the JAD session. She also wants to see an FDD showing the main TIMS functions. Online Case Simulation: S

Session 4: Requirements Modeling INBOX VOICEMAIL TO DO LIST MESSAGES Jesse Baker JAD Session Hi Kate, Good news. You've gotten off to a great start here at SCR... To: kate_mason@scrassociates.com From: jesse_baker@scrassociates.com Subject: JAD session Hi Kate, Jesse Baker Questionnaire Hi Kate, I'd like you to do a survey of former and prospective students... Good news. You've gotten off to great start here at SCR, and I want you to lead the systems development team for TIMS. I want you to use a structured approach with plenty of modeling and documentation. Your first step is to hold a JAD session next week. You should plan for a three-day session. Send a message to the JAD team members, and include a brief explanation of JAD methods and a proposed agenda for the session. Be sure to send me a copy. Jesse Baker Weekend assignment Hi Kate, One more thought about the questionnaire... The JAD team will consist of Jill Martin, the new training group manager; Sandy Wise, records assistant; Amy Hawkins, client service representative; Mark Martin, Web designer, Dave Spencer, programmer; and the two corporate trainers, Meg Harris and Roy Brown. Meg and Roy will move to the new training group, effective immediately. Jesse Baker Weekend assignment Hi Kate, Before we go any further, we need to study the fact-finding results.... By the way, to get some background on our current training activities, take a look at the training records for August and September. You'll find the records in the data library. August was a relatively quiet month, but September was fairly typical. As we get further into this project, I'm sure we'll have to make some cost-benefit estimates and forecasts of training activity. You should be able to find everything you need. Please keep me posted. Good luck! Jesse Baker Session 4: Requirements Modeling INBOX VOICEMAIL TO DO LIST Tasks 1. Group managers said it was OK for their people to attend a three-day JAD session next week. Send a message to the JAD team members, with a brief explanation of JAD methods a and a proposed agenda. 2. Design a questionnaire for former and potential students in SCR's training classes. Also, reply to Jesse's message about sampling. Give her a recommendation and reasons. 3. Read the JAD session summary in the Data Library and put together a list of system requirements, including outputs, inputs, processes, performance, and controls. 4. Draw an FDD of the main functions for TIMS and send it to Jesse. Be sure to show at least one or two levels of detail
