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

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

10

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

11

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!

14

NarrativeAfter 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

15

Reminder – Capstone Project Proposal

Your Capstone Project Proposal is due in two weeks! This means that for the next two weeks you must:

1. Choose a Capstone group to work with for the remainder of semester 5 and all of semester 6!

2. Select a Capstone Project3. 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

16

Client Presentations Here’s a great opportunity to find about some

potential Capstone projects! More client presentations may be scheduled for the

next class.

17

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!
