three system perspectives1
Three System Perspectives
  • Questions (focus-shifting activities):
    • How to define a system (conceptually)?
    • How to design a system (technically)?
    • How to develop a system (operationally)?
r and d type activities
R- and D-type Activities
  • R- / D Interactive Activities
      • Request vs Definition (Conceptual)
      • Reviewing vs Design (Technical)
      • Running vs Development (Operational)
r and d type activities1
R- and D-type Activities
  • R- / D Interactive Activities
      • Request vs Definition (Conceptual: What-to-do)
      • Reviewing vs Design (Technical: How-to-do)
      • Running vs Development (Operational: Way-to-do)
  • Questions (activity-centric approach):
      • On what basis activities/interactions take place?
        • This refers to perspectives to interact
        • This refers to actions to take

Multi-Documentations
  • What are they (document-driven approach)?
    • PRD – Problem Requirements Document
          • Conceptual System
    • PSD – Project Specification Document
          • Conceptual Techinical
    • SDD – Software Design Document
          • Technical system
    • SOM - Software Operator’s Manual
          • Technical  Operational
    • WDSC – Well-Document Source Code
          • Operational system
