Classifies the change in order to distinguish change effects priority and required approval authority.
Changes are classified in accordance with their scope and likely impact in order to provide a key to their subsequent management, review and approval.
A change is classified as Class I (Major) if it affects significant characteristics of a product at that point in time in an agreed configuration baseline. A Class I (Major) change will be indicated if it impacts on, but not limited to:
·performance;
·safety;
·reliability, maintainability, survivability;
·weight, balance, moment of inertia;
·interface characteristics;
·electromagnetic characteristics;
·other product characteristics in the baselined specifications
·interchangeability at the CI level and to all sub-assemblies and parts except the pieces and parts of non-repairable sub-assemblies;
·customer furnished equipment;
·compatibility or interoperability with interfacing CIs, support equipment, support software, spares, trainers, training equipment or training software;
·configuration to the extent that retrospective fit action is required;
·delivered operation or maintenance manuals;
·sources of CIs or repairable items at any level defined by source control drawings;
·skills, manning, training, biomedical factors or human engineering design.
Otherwise, the change is classified as a Class II (Minor) change.
Contractual requirements will determine whether or not customer approval is required for a particular class of change. If a baseline has been subject to approval by the customer, then so too are all changes that affect that baseline. Where internal baselines are established as management vehicles for a development activity, the "customer" can be regarded as the internal customer who "owns" the affected baseline.
The programme specific rules for classification, and the associated treatment processes, will be defined in the programme CMP.
