Annex A
Control Plan

A.1 Phases of the control plan

A control plan covers three distinct phases, as appropriate:
a) Prototype: a description of the dimensional measurements, material, and performance tests that will
occur during building of the prototype. The organization shall have a prototype control plan, if required
by the customer.
b) Pre-launch: a description of the dimensional measurements, material, and performance tests that occur
after prototype and before full production. Pre-launch is defined as a production phase in the process of
product realization that may be required after prototype build.
c) Production: documentation of product/process characteristics, process controls, tests, and
measurement systems that occur during mass production.

Control plans are established at a part number level; but in many cases, family control plans may cover a number
of similar parts produced using a common process. Control plans are an output of the quality plan.

NOTE_1__It is recommended that the organization require its suppliers to meet the requirements of this Annex.
NOTE_2__For some bulk materials, the control plans do not list most of the production information. This
information can be found in the corresponding batch formulation/recipe details.

A.2 Elements of the control plan

A control plan includes, as a minimum, the following contents:
General data
