A System Measure is a measure that quantifies a specific property or characteristic of a system.
- Context:
- It can provide insights into System Performance, behavior, structure, or other attributes, and can be used for analysis, comparison, optimization, or decision-making purposes.
- It can support System Evaluation and System Optimization.
- It can be a Domain-Specific System Measure, applicable to fields such as Information Technology, Engineering, Business Processes, and Ecological Systems.
- It can range from Simple System Measures to Complex System Measures.
- It can range from Stable System Measures to Unstable System Measures.
- It can be relevant, measurable, actionable, comprehensive, and interpretable.
- It can be an aspect of Systems Engineering, Operations Research, Cybernetics, and related disciplines.

- Examples:
- System Performance Measures, which quantify how well a system performs specific tasks or functions compared to some System Baseline Performance or benchmark, including:
- System Output Quality, Precision, Recall, F1 Score for evaluating Machine Learning Models,
- System Throughput, Latency, Response Time for measuring Network Performance,
- System Efficiency, Productivity, Quality for assessing Manufacturing Systems,
- System Adaptability Measures, which assess a system's ability to adapt to changes while maintaining functionality, such as:
- System Robustness - maintaining performance under perturbations,
- System Flexibility - handling a variety of conditions or tasks,
- System Resilience - recovering from disruptions or damage,
- System Evolvability - potential for long-term adaptation,
- System Complexity Measures, which quantify the intricacy or interrelatedness of a system's components, including:
- System Cyclomatic Complexity for software code complexity,
- System Network Complexity metrics like average path length or clustering coefficient,
- System Algorithmic Information Content for the minimum description length,
- System Stability Measures, which assess a system's ability to maintain stability under normal conditions, including:
- Lyapunov Stability in dynamical systems,
- Eigenvalue Analysis in control theory,
- Convergence Measures for algorithms and learning systems,
- Organizational Measures for assessing business processes and structures,
- Social Group Measures for quantifying properties of communities and networks,
- Market Measures for analyzing economic systems and trends.
- Person Measures, such as: user assessment measures.

- System Performance Measures, which quantify how well a system performs specific tasks or functions compared to some System Baseline Performance or benchmark, including:
- Counter-Examples:
- System Simulations or System Predictions, which model or anticipate behavior rather than measuring actual properties,
- Subjective System Attributes like User Satisfaction or Aesthetics, which are based on personal opinions rather than objective measures,
- Meta-Systemic Measures that focus on development processes or sociotechnical factors rather than the system itself,
