Level of practice

Reference level of the Automotive SPICE® model used to define a process according to the level of practice and generic experience. At this level, strong points and improvement potential refer to general expectations realised on a basis of experience. Although meeting the expectations is not obligatory, it is considered a good process realisation practice.

LFT (German “Lieferant“)

German abbreviation for a supplier, see Supplier.

Liquid for further processing

Liquid other than a testing liquid necessary for extraction or analysis, e.g. a solvent used to rinse out analyser filters from e.g. remains of grease.

List of requirements

Set of requirements defined by the customer for the supplier and his/her performance in the scope of the job.

Long-term capability

Used to assess quality capability under actual process conditions after the initiation of series production in adequate time.


“Internal loses” are loses resulting from insufficient quality before dispatch. They are caused by reduced labour efficiency due to additional work, incorrect ergonomics, etc. The term also covers costs related to nonconformities resulting from failure to meet product quality requirements before dispatch (e.g. repeated service provision, repeated production, rework, repeated tests, rejects, etc.). “External loses” are both tangible and intangible loses after dispatch caused by insufficient quality.


Machine capability

Machine capability is determined by comparing the tolerance and variation in production with a single production setting. Mathematical and statistical methods are usually used for assessment and verification considering both short-term variations following a major process-influencing failures and factors independent from the machine itself.

Machine capability test

Machine capability test is a qualification test of machinery used for production of individual products.


Consistently closed regulation cycle consisting of definition of objectives, measurement of objective completion and relevant corrective and improvement actions (e.g. PDCA).

Management system

System to establish policy and objectives and to achieve those objectives.
