  3. IFS410.81 End User Support • While a problem can be harmful or potentially harmful to a firm in a negative way, it can also be beneficial or potentiallybeneficial in a positive way • The outcome of the problem-solving activity is a solution • A decision is a particular selected course of action

  4. IFS410.81 End User Support

  5. IFS410.81 End User Support

  6. IFS410.81 End User Support • Benefits: • Match Capabilities and Challenges • Reduce Communications Gap   • Risks: • Poorly Aimed Systems • Poorly Designed and Documented Systems   • Inefficient Use of Information Resources   • Loss of Data Integrity • Loss of Security     • Loss of Control  

  7. IFS410 End User Support • Definition: SYSTEM • Group of interrelated components working together to solve a problem

  8. IFS410.81 End User Support • A structured problem consists of elements and relationships between elements, all of which are understood by the problem solver • An unstructured problem is one that contains no elements or relationships between elements that are understood by the problem solver • A semi structured problem is one that contains some elements or relationships that are understood by the problem solver and some that are not

  9. IFS410.81 End User Support • Programmed decisions are: • repetitive and routine • a definite procedure has been worked out for handling them • Non programmed decisions are: • novel, unstructured, and unusually consequential. There’s no cut-and-dried method for handling the problem • it needs a custom-tailored treatment

  10. End User Classification • Environment: home or personal user versus corporate or organizational user • Skill level: novice, unskilled, semi-skilled, expert • Principal applications: for example, word processing, e-mail, accounting • Frequency of use: occasional, frequent, constant • Features used: basic, intermediate, and advanced • Location: internal user versus external user

  11. Resources End Users Need (Overview) • Basic Hardware • Add-on Peripherals • Hardware maintenance and upgrades • Software and software upgrades • Supplies • Data and information • Technical support • Facilities, administration, and overhead

  12. Hardware Maintenance and Upgrades • Hardware warranty period • Extended warranty • Common Upgrades • Additional internal memory • Increased CPU speed • Additional hard disk drive space • Increased peripheral speed (e.g., modem or printer) • Enhanced sound system • CD burner • DVD player or burner • Other system components

  13. Software and Software Upgrades • Operating system • Applications software packages • Software upgrades to new versions

  14. Technical Support • Installation assistance • Training courses • Training materials • Books and magazines • Access to help desks and technical support

  15. Total cost of ownership • All of the accumulated costs to purchase, upgrade, and support a personal computer system over its expected useful lifetime. • The total cost of ownership includes • Hardware • Software • Network • Information • Training • Technical support costs
