Performance Measure

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

• Context:
  • output: Performance Score.
  • It can be a Performance Metric.
  • It can range from being a Task Performance Measure, Algorithm Performance Measure, to being a System Performance Measure.
  • It can range from being a Historical Performance Measure to being a Predicted Performance Measure.
• Example(s):
  • a System Performance Metric, such as a computing system performance metric and business performance measure.
  • a Algorithm Performance Metric.
  • a Task Performance Measure, such as a classification performance measure, or a ranking performance measure.
• See: Performance Improvement.

  • 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.
