PIECES Framework

A checklist for identifying problems with an existing information system.
  • Performance
    • Throughput
    • Response Time
  • Information (and Data)
    • Outputs
      • Lack of any information
      • Lack of necessary information
      • Lack of relevant information
      • Too much information – information overload
      • Information that is not in a useful format
      • Information that is not accurate
      • Information that is difficult to produce
      • Information that is not timely to its subsequent use
    • Inputs
      • Data is not captured
      • Data is not captured in time to be useful
      • Data is not accurately captured – contains errors
      • Data is difficult to capture
      • Data us captured redundantly – same data is captured more than once
      • Too much data is captured
      • Illegal data is captured
    • Stored Data
      • Data is stored redundantly in multiple files and/or databases
      • Stored data is not accurate
      • Data is not secure from accident or vandalism
      • Data is not well organized
      • Data is not flexible – not easy to meet new information needs from stored data
      • Data is not accessible
  • Economics
    • Costs
      • Costs are unknown
      • Costs are untraceable
      • Costs are too high
    • Profits
      • New markets can be explored
      • Current marketing can be improved
  • Control (and Security)
    • Too little security or control
      • Input data is not adequately edited
      • Crimes (e.g. fraud, embezzlement) are (or can be) committed against the data
      • Ethics are breached on data or information – refers to data or information getting to unauthorized people
      • Redundantly stored data is inconsistent in different files or databases
      • Data privacy regulations or guidelines are being (or can be) violated
      • Processing errors are occurring (either by people, machines, or software)
      • Decision- making errors are occurring
    • Too much control or security
      • Bureaucratic red tape slows the system
      • Controls inconvenience customers or employees
      • Excessive controls cause processing delays
  • Efficiency
    • People, machines, or computers waste time
      • Data is redundantly input or copied
      • Data is redundantly processed
      • Information is redundantly generated
    • People, machines, or computers waste materials and suppliers
      • Effort required for tasks is excessive
      • Materials required for tasks is excessive
  • Service
    • The system produces inaccurate results
    • The system produces inconsistent results
    • The system produces unreliable results
    • The system is not easy to learn
    • The system is not easy to use
    • The system is awkward to use
    • The system is inflexible to new or exceptional situations
    • The system is inflexible to change
    • The system is incompatible with other systems
    • The system is not coordinated with other systems
