| - | **Performance Specifications** is a document that specifies the operational requirements of a component or installation. Simply put, a [[ddsf:private:cookbook:06_append:glossary:p:performance|performance]] specification tells the contractor what the final installed product must be capable of doing. | + | **Performance Specifications** is a document specifying operational requirements of a component or installation. In other words, a [[dido:public:ra:xapend:xapend.a_glossary:p:performance|performance]] specification informs the contractor what the final installed product capabilities are. In contrast, see [[dido:public:ra:xapend:xapend.a_glossary:c:conformancespecification]]. |
| - | The contractor is not instructed as to how to accomplish the task of meeting the performance specification requirements - only as to how the component must function after installation. | + | In this case the buyer simply explains problems the product should solve and the supplier provides such. In essence this is less rigid than conformance specification. |
| - | For example, a performance specification may be used in the construction of an industrial pumping system. The specification would provide a required pumping rate (say 500 gallons per minute), a required pressure (20 psi) and the difference in height between the pump and the final destination (+40 feet). | + | Examples of what typical specifications may be like include; |
| - | The specification will also state that the liquid to be pumped will be at a temperature of 140°F and is corrosive (pH of 3). It is up to the contractor to provide pumping equipment that meets or exceeds the requirements stated in the specification. In many cases the contractor will also be required to test equipment to make sure that is operating properly, and will provide operations manuals. | + | * Required quality levels |

| + | |||
| + | * When the supplier has more technical or relevant skills than that of the buyer | ||
| + | * When technology is constantly changing in the suppliers industries in which case it will be hard to specify methodologies | ||
| + | * When there is a clear criterion for evaluating alternative solutions suggested by the suppliers competing for the contract | ||
