  1. Chapters 16 and 17 System Analysis, Designs, and Development

  2. Systems Development Horror Stories • Blue Cross, $120 million • Bank America, $60 million and $4 billion • SAP overruns • “Bob One”, $50 thousand • “Bob Two”, $30 thousand

  3. Steps in Systems Development(Bob Two) • Initial Investigation • Systems Survey • Feasibility Study • Information Needs and System Requirements • Systems Analysis Report

  4. Data Gathering • Interviews - vitally important • Questionnaires - cheap, anonymous • Observation - not really what you were told? • Systems documentation - ‘nuff said?

  5. Feasibility • Technical • Operational • Legal • Scheduling • Economic

  6. Reengineering • Outcomes, not tasks • Output users perform processes • Information producers become processors • Centralize and decentralize (simultaneous) • Integrate across teams • Flatten organization chart (empower) • Capture data once (sound familiar?)

  7. Resistance to AIS ChangesMore “Bob” stories • I’ve been a CPA for 25 years…… • I just passed the CPA exam and …… • My professor told me…… • My boss still wants hard copies…… • Upstairs wants IT, but won’t pay for IT… • AKA, life on the cheap

  8. Solving HR/AIS Problems • Get people talking • Ask, do not tell • We discussed, not I want • How can we get the boss to accept our idea? • What do you think we should do? • Let employees have an opportunity for feedback • Document and protect yourself

  9. RFP • Request for Proposal • Force our team to quantify our needs • Force suppliers to address our needs • not just supply their standard product • Difficulty: degree of customization

  10. SDLC Systems Development Life Cycle • Analysis • Conceptual Design • Physical Design • Implementation and Conversion • Operations and Maintenance • Begin again...

  11. Project Management Tools • Traditional Tools (now electronic) • Pert • Gantt • Development Tools • to develop and track • Computer Aided Software Engineering (CASE)

  12. Software Development Options • Canned • not modified • very modified • Custom built in-house • Turnkey

  13. Project Evaluation • Benchmarking • IPO cycle time / accuracy • Point Scoring (Prob 18.4) • to meet our design • so, how well did we design? • Requirements costing • additional cost for our wish list

  14. Custom Vs. Canned • Select custom if • significant competitive advantages exist • the product cannot be obtained as “canned”

  15. Prototypes • Prototype • fully functioning system • used to identify problem areas • Proof of Concept • one step below a prototype • low cost experiment • DHS example

  16. DHS Proof of Concept Brad Howarth & Javier Seymore

  17. Employer-DesiredTraits for Employees (Pro2pro) • 26% Work ethics • 20% Positive attitude • 19% Social skills/Team player • 11% Ambition • 9% Flexibility • 8% Attention to detail • 4% Communication/Writing skills • 3% Computer savvy • 1% Other
