F451- Systems Life Cycle mind map

A detailed mind map of each stage of the systems life cycle. I'm sure that some will vary but it should all contain the same points...

  • Systems Life Cycle
    • Definition
      • Problem is identified
      • Feasibility Study
        • TELOS
          • Technically (Is it possible within time? At all?)
          • Economically (Affordable?)
          • Legally (Abide by laws? Health & Safety?)
          • Operationally (Will it work with rest of company?)
          • Socially (Employees? Training? Redundancies?)
    • Analysis
      • Information Collection
        • Observations
        • Questionnaires
        • Interviews
      • System requirements
        • Hardware
        • Software
    • Evaluation
      • Check system follows specs
      • Compare result and plan
    • Testing
      • Bugs
        • Found & Fixed
      • Meeting specs?
      • Intentionally try break system
      • Production of Test Data
      • Alpha
      • Beta
    • Design
      • Relationships in system
      • Interface (GUI) layouts
      • Detailed enough, anyone can understand
      • Algorithms
    • Documentation
      • Allows maintenance and development
      • User
        • Primary user, contains instructions
      • Technical
        • I.T. technicians so they can fix problems
    • Maintenance
      • Corrective
        • Fix bugs
      • Perfective
        • Improve performance
      • Adaptive
        • Alter software due to external changes (VAT)
    • Implementation
      • Prototypes
        • Evolutionary
          • Kept and improved
        • Throw-Away
          • Made, feedback recorded
          • Another made with feedback
    • Installation
      • Pilot
        • Trial of new used before completely installed
      • Parallel
        • Old is run alongside new then replaced
      • Direct
        • Completely replace old with new
      • Phase
        • Slowly change old to new
