Performance Defined
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.
For instance, in several sports such as tennis and golf, there have been technological improvements in the apparatuses used in these sports. The improved apparatus in turn allows players to achieve better performance with no improvement in skill by purchasing new equipment. The apparatus, the golf club and golf ball or the tennis racket, provide the player with a higher theoretical performance limit.

Famous quotes containing the words performance and/or defined:
“When a book, any sort of book, reaches a certain intensity of artistic performance it becomes literature. That intensity may be a matter of style, situation, character, emotional tone, or idea, or half a dozen other things. It may also be a perfection of control over the movement of a story similar to the control a great pitcher has over the ball.”
—Raymond Chandler (1888–1959)
“There is no such thing as a language, not if a language is anything like what many philosophers and linguists have supposed. There is therefore no such thing to be learned, mastered, or born with. We must give up the idea of a clearly defined shared structure which language-users acquire and then apply to cases.”
—Donald Davidson (b. 1917)
