NOTE    The plans and schedules enable allocation of resources for the tasks to be carried out and enable monitoring of progress. The plans are based on the decision taken concerning the introduction point and effectivity of the change. They cover both production embodiment and retrospective embodiment, before or after the delivery of the product as appropriate. An approved change is planned and scheduled for implementation in all documents, facilities, hardware and software impacted change. The implementation is carried out in accordance with the plan. Implementation of a change involves the release of new or revised configuration documentation (Assured Product and Support Information (APSI)) including requirements and design information.

NOTE    Note 1: Design intent includes the design of the support system, the manufacturing system etc. Acceptance of a Variance does not change the PIF baseline.

Note 2: Different organizations have one or more words to describe departures from the design baseline, thus this definition is intended to cover terms such as:

• waiver
• concession
• non-conformance
• production permit
• acceptable fault
• acceptable limitation

NOTE    Note 1: The term verified is used to designate the corresponding status.

Note 2: Confirmation may comprise activities such as:

• Performing alternative calculations
• Comparing a new design with a similar proven design
• Undertaking tests and demonstrations
• Reviewing the design-stage documents before release
