System Performance Measure

A System Performance Measure is a system measure of some designed system.

• Context:
  • output: Performance Score.
  • It can (typically) evaluate System Performance through measurement criteria.
  • It can (typically) assess Process Efficiency through output analysis.
  • It can (typically) monitor Task Achievement through result tracking.
  • It can (typically) quantify Resource Utilization through usage measurement.
  • ...
  • It can (often) support Performance Optimization through data analysis.
  • It can (often) enable Comparative Analysis through benchmarking.
  • It can (often) guide Decision Making through performance insights.
  • It can (often) identify Improvement Areas through gap analysis.
  • ...
  • It can range from being a Designed System Performance Measure to being a Natural System Performance Measure, depending on its system type.
  • It can range from being a Historical Performance Measure to being a Predicted Performance Measure, depending on its temporal focus.
  • It can range from being a Qualitative Performance Measure to being a Quantitative Performance Measure, depending on its measurement type.
  • It can range from being a Domain-Specific Performance Measure to being a General Performance Measure, depending on its scope.
  • It can range from being an Operational Performance Measure to being a Strategic Performance Measure, depending on its organizational level.
  • It can range from being a Real-Time Performance Measure to being a Retrospective Performance Measure, depending on its measurement timing.
  • ...
  • It can integrate with Performance Management Systems for data collection.
  • It can support Continuous Improvement through tracking capability.
  • It can inform Strategic Planning through performance insights.
  • ...
• Examples:
  • Designed System Performance Measures, such as:
    • Computing System Metrics, such as:
      • CPU Usage Measure for processor efficiency.
      • Response Time Measure for system responsiveness.
    • Business Performance Measures, such as:
      • Profitability Ratio for financial health.
      • Market Share Metric for competitive position.
  • Task Performance Measures, such as:
    • Classification Performances, such as:
      • Accuracy Metric for prediction quality.
      • Precision Score for classification reliability.
    • Ranking Performances, such as:
      • Relevance Score for ranking accuracy.
      • Order Metric for sorting efficiency.
  • Organizational Performance Measures, such as:
    • Key Performance Indicators, such as:
      • Sales Growth Rate for revenue tracking.
      • Employee Turnover Rate for workforce stability.
  • ...
• Counter-Examples:
  • Anecdotal Feedback, which provides subjective observations without measurable criteria.
  • Process Description, which explains system operations without performance assessment.
  • Task Checklist, which lists required actions without quality evaluation.

  • Performance is a measure of the results achieved. Performance efficiency is the ratio between effort expended and results achieved. The difference between current performance and the theoretical performance limit is the performance improvement zone.

    Another way to think of performance improvement is to see it as improvement in four potential areas. First, is the resource INPUT requirements (e.g., reduced working capital, material, replacement/reorder time, and set-up requirements). Second, is the THROUGHPUT requirements, often viewed as process efficiency; this is measured in terms of time, waste, and resource utilization. Third, OUTPUT requirements, often viewed from a cost/price, quality, functionality perspective. Fourth, OUTCOME requirements, did it end up making a difference.

    Performance is an abstract concept and must be represented by concrete, measurable phenomena or events to be measured. Baseball athlete performance is abstract covering many different types of activities. Batting average is a concrete measure of a particular performance attribute for a particular game role, batting, for the game of baseball.

    Performance assumes an actor of some kind but the actor could be an individual person or a group of people acting in concert. The performance platform is the infrastructure or devices used in the performance act.

    There are two main ways to improve performance: improving the measured attribute by using the performance platform more effectively, or by improving the measured attribute by modifying the performance platform, which in turn allows a given level of use to be more effective in producing the desired output.
