  1. END USER COMPUTING Critical Issues

  2. Key Issues in IS ManagementNeiderman, Brancheau, Wetherbe, MISQ, 1991(Gray, et. al.) • Developing an information architecture • Making effective use of data • Improving IS strategic planning • Recruiting, and developing human resources • Facilitating organizational learning and use of IS • Building a responsive IT infrastructure • Aligning IS with the enterprise • Using IS for competitive advantage • Improving the quality of software development • Developing telecommunications systems

  3. Type I (Procedure) High volume Low transaction cost Well structured Measurable Process & efficiency Data Clerical Type II (Goal) Low volume High trans. value Poorly structured Hard to measure Goal & effectiveness Concepts Mgrs, professionals Types of Information Systems Sprague & Watson, DSS for Management, Prentice Hall, 1996

  4. IS Development Approaches • Systems Development Life Cycle • Information Center (DSS) • Object and Component

  5. Type ILarge Systems • Intercommunications among applications • Formal methodologies • CASE technologies • Purchased products • Outsourcing

  6. Type ISDLC • Type I systems • Large and Costly • Cost justified • Formal stages of evaluation • Stages carefully reviewed and formally approved • Data, Process, Communications

  7. Type IIInformation Center (DSS) • Type II systems • Relatively small and inexpensive • Value justified • Prototyping and evolutionary design • Data, Dialog, Model

  8. End User Computing (EUC) End User Computing refers to systems in which the user does some of the programming. Arises from: • Capacity of Computers • Cost of Hardware • Friendly Software • Data Communications

  9. EUC Issues • Data extraction (warehouses) and availability • System design and development • Management and control • New technologies: EIS, GDSS and Artificial Intelligence, Expert Systems and Groupware

  10. Prototyping & Iterative Design • Data • Trial Solution • User Experimentation • Revised Solution

  11. Object Oriented(Event Driven) • User owned • Small and experimental • Dialog driven, reusable code • Combines data and process

  12. Object Issues • Reliability of tools and software • Design methodologies • Standards and portability • Extent of value

  13. Type I Design Systems Development Life Cycle: Formal development of systems in progressively detailed stages • Initial investigation • Feasibility • General design • Detailed design • Implementation • Maintenance

  14. Type I Design:

  15. Type II Design DATA MODEL DIALOG USER

  16. Development Roles • User • Intermediary (Chauffeur) • Builder • Technical Support • Toolsmith

  17. Design Philosophy • Functional • Entity • Dialogue • Event

  18. Distributed Management • Business within a business • IS internal partnerships • Virtual organizations • Outsourcing and consultants • Personnel management

  19. Ownership Data Process User Owned IS Owned

  20. Information Access:IT User Partnership
