"However beautiful the strategy, you should occasionally look at the results." ~ Churchill
This is the role of measures of effectiveness and measures of performance.
- Measures of Effectiveness - The operational measures of success that are related to the achievements of the mission or operational objectives evaluated in the operational environment, under a specific set of conditions.
- Measures of Performance - Measures that characterize physical or functional attributes relating to the system operation, measured or estimated under specific conditions.
- Key Performance Parameters - Represent the capabilities and characteristics so significant that failure to meet them can be cause for reevaluation, reassessing, or termination of the program.
- Techncial Performance Measures - Attributes that determine how well a system or system element is satisfying or expected to satisfy a technical requirement or goal.
