  4. Lessons from DP Era • Need to understand the process of developing complete IS • More thorough requirements and data analysis • More appropriate justification of investments • Less creative, more structured approaches to programming, testing, and documentation • Extended project management to coordinate user and DP functions • Need to plan the inter-related set of IS required by the organization

  5. Lessons from MIS Era • Justification of IS investments not simply a matter of financial analysis • Databases require large restructuring projects and heavy user involvement • IS resource needs to move from a production to a service orientation • Need for organizational policies, not just DP methodologies • PCs enable better MIS to be developed provided users and IS people focus on information needs

  7. Types of SIS • Those that share information with customers and/or suppliers thereby changing business relationships • Those that effectively integrate the use of information in organizational value-adding processes • Those that enable organizations to develop, produce, and market new or enhanced products or services • Those that provide managers with information to support development and implementation of strategy • Examples: American Hospital Supply, International Enterprise Singapore, Amazon.com, and Safeway

  8. Success Factors of SIS • External focus instead of internal focus • Adding value instead of cost reduction • Sharing the benefits internally and externally • Understanding customers and their needs • Business driven instead of technology driven • Incremental development instead of total development • Using information gained to develop business

  9. Applications Portfolio in the SIS Era • Strategic applications • Critical for future success • High potential applications • May be critical for future success • Examples • Just-in-time links to suppliers • Sales forecasting system • Market analysis system • Examples • IS links to business partners • Manpower planning system • Expert fault diagnosis system • Key operational applications • Critical for current success • Support applications • Valuable but not critical for success • Examples • Inventory management system • Product costing system • Maintenance scheduling system • Examples • General accounting system • Time recording system • Payroll system
