IT capabilities & their Organizational Impacts IT can be used to connect two parties who would otherwise communicate through an intermediary Disintermediation IT allows the detailed tracking of task status, inputs, and outputs Tracking IT allows the capture and dissemination of knowledge and expertise to improve the process Knowledge Management IT can enable changes in the sequence of tasks Sequential IT can bring vast amount of detailed information Informational IT can bring complex analytical methods Analytical IT can replace or reduce human labor in a process Automational IT can transfer information with rapidity and ease across large distances Geographical IT can transform unstructured processes into routinized transactions Transactional Organizational Impact / Benefit Capability
  • 11. Steps in Business Reengineering
    • Develop the business vision and process objectives

    • Identify the opportunities for applying information technologies
    • Build a prototype of the new process
  • 12.
    • Automation: Using computer to speed up existing tasks
    • Rationalization of procedures: streamline procedures, eliminate bottlenecks
    • Business reengineering: Radical redesigning of business processes, combining steps to cut waste, eliminate repetitive tasks to improve cost, quality and maximize the benefits
    • Paradigm shift: Radical reconceptualization of the nature of the business and organization
  • 13. Redesigning the Business Process
    • A set of logically related tasks performed to achieve a defined business outcome
      • Combine steps
      • Eliminate repetitive steps

  • 16. Total Quality Management (TQM)
    • TQM: A concept that makes quality control a responsibility to be shared by all people in an organization
    • IS contributes to TQM:
      • Simplifying the product & production
      • Benchmarking: Setting strict standards for products, services or activities and measuring organizational performance against those standards
      • Use customer demand as a guide to improve product and services
      • Reduce cycle time
      • Improve the quality and precision of design
      • Increase the precision of products
  • 17. System Development
    • System Development: The activities that go into producing an information systems solution to an organizational problem or opportunity
    • Systems analysis: The analysis of a problem that the organization will try to solve with an information system
  • 18. Feasibility
    • Determining whether a solution is achievable given the organizational resources & constraints
      • Technical: Available technical resources
      • Economic: costs vs. benefits ?
      • Operational: fits the organization ?
  • 19. Information Requirements
    • A detailed statement of the information needs that a new system must satisfy
    • Who needs what information, when, how?
    • Basis for the system design: details how a new system will meet requirements
      • Logical design: Lays out the components of the information system and their relationship to each other as they would appear to users
      • Physical design: The process of translating the abstract logical model into the specific technical design for the new system.
  • 20. Design Specifications
    • Output: medium, content, timing
    • Input: origins, low, data entry
    • User interface: simplicity, efficiency, logic
    • Database design: logical data relations
    • Processing: computations, program modules
    • Manual procedures: activities, performers, when
    • Controls: input, processing, output, procedural
    • Security: access, catastrophe plans, audit trails
    • Documentation: operations, systems, user
    • Conversion: transfer files, new procedures
    • Training: techniques, modules, facilities
    • Organizational changes: task, job, process redesigns
