  1. Applying IT can be difficult to do • Systems analysis and design is about understanding and applying methodologies to help create effective information systems

  2. A brief introduction to the WCA • Let’s look at the Work Centered Analysis (WCA) as its applied to the Amazon case • We’ll go into this in much more detail next class...

  3. A brief introduction to the WCA

  4. Phases in Building and Maintaining Systems • Initiation • Development • Implementation • Operation & Maintenance

  5. Another view of Development • Prototyping allows you to use “successive approximation” to get closer to an optimum solution

  6. Design phases can be applied to non-IT projects • Have you experienced similar phases in any type of project you’ve undertaken? • Buying a car? • Renting an apartment?

  7. IT-Based Innovations in Business Function • Product design systems • Procurement systems • Manufacturing systems • Sales and Marketing systems • Delivery systems • Customer service systems • Finance systems

  8. Progress in IT • Miniaturization, speed and portability • Connectivity; convergence of computers and communications

  9. Progress in IT (continued) • Use of digitized information and multimedia • Improved software techniques and human interfaces

  10. Obstacles when Applying IT in the “Real World” • Unrealistic expectations • Difficulty in building and modifying systems • Difficulty in interfacing/integrating systems • Organizational inertia/change management

  11. It is really hard to predict the future in IT • What about Bill Gates, stating that no one would ever need more than 640KB of memory on a PC? • What type of PC do you think you’ll be using in 5 years?

  12. Dell Computer Case • What role does information technology play in running Dell’s business? • Dell has moves toward a “virtual value chain.” What is this? What are the pros and cons of this approach?
