Setzteile
Fertigt eine Organisation Baugruppen und hat dazu Teile zu verwenden, bei denen der Kunde vorschreibt bei welchem Lieferanten diese zu beziehen sind, spricht man von Setzteilen. In diesem Fall liegt die Qualitätsverantwortung trotzdem bei der Organisation. D.h. sie muß durch geeignete Maßnahmen die Einhaltung der Qualitäts-anforderungen an diese Teile sicherstellen.

Parts specified by the customer / directed parts
These are parts where an organisation manufactures assemblies and in doing so must use parts where the customer specifies the supplier. In this case the organisation is still responsible for the quality – that is, the organisation must take appropriate measures to ensure that these parts comply with the quality requirements.

While the rollout has been hampered somewhat by the necessity of adding "directed suppliers" (chosen by Lacks' clients for their specialized capabilities and often located offshore), the company is meeting its objectives in terms of supplier participation in the new system.
