SA Capstone Requirements and DesignWeek 1SYST36367Winter 2013Instructors: Jerry Kotuba & Joe Varrasso
Lesson Objectives • System Vision • Existing System Description • Project Proposal • Client Presentations • Group Meetings
System Vision • Before starting detailed Systems Analysis activities, a System Vision document is very helpful to: • Determine whether a Systems Request merits further investigation • Summarize the justification for a system • The System Vision document should: • Summarize the motivations, scope and benefits of a proposed system • Allow readers to decide whether the system warrants a more detailed examination • Entice interested individuals to continue reading related documents • Serve as the basis for an “elevator pitch” to quickly and effectively inform partners/investors about the merits of the project
Identify the Problem • System Vision Document • Problem Description • What is the problem and idea for the solution? • System Capabilities • What are the capabilities the new system will have? • Helps define the scope • Business Benefits • The benefits that accrue to the organization • Tangible (in dollars) and intangible benefits Systems Analysis and Design in a Changing World, 6th Edition

Existing System Description- Fact Finding • To understand the existing system, your group should perform some Fact Finding which includes: • Interviewing various stakeholders • Collecting and analyzing system artifacts • Possibly observing users and/or surveying them • Drawing a Context Diagram of the system
Existing System Description- Artifacts • Request and collect artifacts to better understand the current business processes • Sample artifacts include: • Purchase Orders • Invoices • Reports • Instruction Manuals • Training Materials • Current system software or simulation of this software • Basically all documentation that they have or use relative for doing their business
Existing System Description – Context Diagram • Remember that there are only four symbols in DFDs: • External Entity (source or sink of data) • Process • Data Flow • Data Stores (not used in a Context Diagram!) • Remember that at least one end of the Data Flow must be connected to a Process!
Data Flow Diagrams *From: Systems Analysis and Design, Ninth Edition, Gary B. Shelly & Harry J. Rosenblatt, Course Technology, CENGAGE Learning, 2012 DFD Symbols
Existing System Description – Context Diagram • In Class Exercise
Narrative • After completing the existing system’s Fact Finding your group should be in a good position to write a Narrative to describe the project. • This Narrative can serve as an excellent starting point for subsequent analysis and design activities
Reminder – Capstone Project Proposal • Your Capstone Project Proposal is due in two weeks! • This means that for the next two weeks you must: • Choose a Capstone group to work with for the remainder of semester 5 and all of semester 6! • Select a Capstone Project • Complete your Capstone Proposal • One key part of the Capstone Proposal is the System Vision • Remember that your proposal and project should look beyond a single customer’s current needs
Client Presentations • Here’s a great opportunity to find about some potential Capstone projects! • More client presentations may be scheduled for the next class.
Group Meetings • Please break into your groups to get started on selecting a Capstone Project and/or planning the first deliverable. • If you do not have a group then use this time to form a group. Remember to choose your group wisely as your group will be expected to work together for all of the 5th and 6th semesters!
