Citation - Taylor, R. S. (1986). Value-added processes in information systems. Norwood, N.J.: Ablex.


Questions: # What does an information system do for human beings to justify its cost?

  1. Can we relate the system costs (value added in the economist's term) to the user enhancements added by the system (value added in the context of this book)?
  2. What will be the cost in time, effort, and money that users, sitting in particular environment with particular problems, must invest to obtain useful information from any particular system?


  • information system
    • the information system is a operating information system, its practice-driven and in “ordinary contexts of practical action”.
      • “We have systems that work,. That is to say, these fortuitous mixtures of professional know-how and technology called systems gather, operate on, and provide information to an amazing array of people in every kind of imaginable situation.” 我們有可用的系統。也就是說,這些天然混成專業技能與技術的系統,使各種情境中的人們得以聚集、運作、與提供資訊。
  • user-driven model, not content-driven or technology-driven model


  • 由歷史學出身的 Taylor,似乎傾向用一種客觀且寬容的態度來觀察這個複雜的人間社會。系統,對他而言,似乎是對社會秩序的隱喻。
