  1. 10. REDESIGNING THE ORGANIZATION WITH INFORMATION SYSTEMS

  2. Learning Objectives • Demonstrate how building new systems can produce organizational change • Explain how organization can develop suitable info systems • Identify core activities in systems development process *

  3. Learning Objectives • Analyze organizational requirements for building successful systems • Describe models for determining business value of info systems *

  4. Information Systems Plan Direction of system development: • Rationale • Current situation • Management strategy • Implementation plan • Budget *

  5. Enterprise Analysis (Business Systems Planning) Organization-wide information needs in terms of: • Organizational units • Functions • Processes • Data elements Helps identify key entities & attributes in organization’s data *

  6. Requirements Analysis Revisited • Interview • Document-oriented approach: descriptive paperwork • Form-oriented approach: input (application) and output (report) forms.

  7. Critical Success Factors • Small number, easily identifiable operational goals • Shaped by industry, manager, environment • Believed to assure firm’s success. • Used to determine organization’s information requirements *

  8. Using CSFs to Develop Systems • Collect manager’s CSFs • Aggregate, analyze individual’s CSFs • Develop agreement on company CSFs • Define company CSFs • Use CSFs to develop information system priorities • Define DSS & databases *

  9. Logical Design Revisited • Organize by relevance and usage • The results can be implemented using many tools and platforms (portable) • The results do not change as rapidly (stable)

  10. Spectrum Of Organizational Change • Automation • Rationalization • Business reengineering (BPR) • Paradigm shift

  11. Spectrum Of Organizational Change • Automation: using technology to perform tasks efficiently (physical design, implementation / testing)

  12. Spectrum Of Organizational Change • Rationalization of procedures: streamline sops; Eliminate bottlenecks. Find a different way to organize the processes. (Logical Design level)

  13. Spectrum Of Organizational Change • Business Reengineering: radical redesign of processes to improve cost, quality, service; Maximize benefits of technology. Accomplish the same goal with different means. (Requirements Analysis level)

  14. Spectrum Of Organizational Change:Paradigm Shift • Paradigm is a complete mental model of how a complex system functions • A paradigm shift involves rethinking the nature of the business, the organization; A complete re-conception of how the system should function. (Enterprise View level) *

  15. Risks & Rewards High RISK Low Low High RETURN

  16. IT Capabilities & Impacts • Transactional:transforms unstructured processes to routine transactions to improve efficiency • Geographical:IT makes processes independent of location • Automational:replaces, reduces human labor * Source: Davenport & Short “The New Industrial Engineering”(1990)

  17. IT Capabilities & Impacts • Analytical: can bring complex analytical methods to bear on process • Informational:makes vast amounts of detailed information available • Sequential:enables changes in sequence, parallel tasks * Source: Davenport & Short “The New Industrial Engineering”(1990)

  18. IT Capabilities & Impacts • Knowledge management:allows capture, dissemination of knowledge, expertise • Tracking:allows detailed tracking of task status, inputs, outputs • Disintermediation:connects parties who otherwise depend on an intermediary * Source: Davenport & Short “The New Industrial Engineering”(1990)

  19. System Development Process • Systems analysis • System design • Programming • Testing • Conversion • Production & maintenance *

  20. Systems Analysis • Analysis of problem to be solved with an information system • Feasibility study: can problem be solved within constraints? • The system to be analyzed is the business system. *

  21. Systems Analysis: Feasibility • Technical:assess hardware, software, technical resources • Economic: will benefits outweigh costs • Operational:is solution desirable within existing conditions? • Information requirements:detailed statement of new system needs *

  22. Role Of End Users • Users drive systems effort • Must have sufficient control to ensure system reflects business priorities, needs • Functional users drive system needs • Most of the projects fail because of user resistance

  23. Completing System Development Process • Programming:translating needs to program code • Testing:does system produce desired results? • Assess the success of the system (must know the goals) *

  24. Managing Change • User involvement & influence • Management support • Level of complexity & risk • Project size • Project structure • Experience with technology *

  25. Managing Implementation • Increase user involvement • Detect, overcome user resistance, counter implementation • Control risk factors • Employ ergonomics *

  26. Ergonomics: Interaction of people and machines. The easier the task, the higher the acceptance • Work environment • Design of jobs • Health issues • End-user interface of info system *

  27. Scoring Model / Factor Rating: • Identify desirable features • Provide weights for each (add to 1.00) • Look at each alternative: • Which features are present? • To what extent (as an amount)? • Score the alternative

  28. Scoring Model: • Rank-order the alternatives • Select highest ranked option *
