NOTE    A defect may result in a degradation in the ability to perform an intended function and may be an incipient failure.

NOTE    Deferments are applied to actual product instance. They enable product instance that has known faults to continue to be used (possibly with limitations). Deferments have to be authorised and can have limitations associated with them (these may be role based or stress related). Additionally, an authoriser may only be empowered to authorise certain classifications of deferment. It is not usual to fit product instance to which deferments apply to parent product instances. An product instance with a deferred fault will continue in use whilst it is fitted, but will be classified as unserviceable once removed from the end product instance. Records of deferments and who authorised them must be kept.

NOTE    A configuration element could have a large quantity of information asssociated with it. Examples to consider whenn defining what is required are: design data, configuration item interface specifications, interface control documentation, analysis of support requirements, support solution and technical publications.

NOTE    The requirements are usually derived from individual customer/companies policies/standards (eg IT/B2B/CM/QA etc) and the customers contractual requirements (eg CMP/CO) create the outline Information Management (IM) model. The process of defining the structure and organisation of data in an media for a digitally driven virtual enterprise. An information model is produced which defines how the product data will be held. It may describe a set of tools, but preferably it will specify an open data architecture. Define the associations and relationships between data and documents and how that information is represented in different views. (EIA 836 (2549)).

NOTE    This defines the methodology and creates a structured set of IM rules.This defines the methodology and creates a structured set of IM rules.

NOTE    The nature of interfaces depends on the nature of the elements themselves They may include the physical and functional attributes of the connection, spatial relationships, parent child relationships and other forms of reference, such as the links to product, support and configuration data. This process enables the check list, used when changes to elements are proposed, to be developed ensuring that all consequences of proposed changes are considered and it also provides a starting point for the development of product structures.

NOTE    Examples: conceptual, design, functional, physical, spatial, zonal.

NOTE    Definition of the scope and depth of configuration breakdown is required will be an iterative process. The latter being largely driven by the output of the support engineering process.

NOTE    The requirement is for a single product structure that provides a controlled and complete product definition for the PIF across the product life cycle. The product structure view requirements are established within Information Management - Identify product structure views (AAM CM A1322). In addition AAM CM A13 produces the Information management rules that act as a constraint on this process.

NOTE    It may be necessary to define several deployment environments for a given PIF, each giving rise to a different support solution.

The deployment environment may include details of:

• the number of products to be deployed and their groupings
• the duration of deployments
• the intended frequencies, duration (time and distance) , profile and nature of operating periods and support opportunities
• the anticipated physical and climatic environments in which usage or support is expected to occur
• the assumed capability of each identified support location in terms of facilities, infrastructure and personnel
• assumptions relating to the availability of specific and critical support facilities, capabilities or organizations
• local commercial, social or political constraints affecting the provision of support

NOTE    The level of analysis required will be dependant upon the nature of the change taking into account effects on Support engineering and Resource management and impacts on other approved changes.

NOTE    The information strategy is usually derived from individual customer/companies policies/standards and the customers contractual requirements to create the outline Information Management (IM) model.

NOTE    The development stage of the change will identify a choice of solutions that may meet the change requirement. Viable solutions are developed so that the impact of each can be assessed.

NOTE    The physical/functional aspects will contain a number of classified elements and relationships that are linked together in a hierarchical fashion. Some elements will be unique to the functional element which defines the operation of the PIF, and some unique to the physical element to support the representation of the build of the PIF. The structurei ncludes parent-child relationships, aspects, networks and classification of products.

NOTE    Disposed elements may include:

• waste products arising from support tasks (eg dirty oil)
• resources no longer required for planned tasks
• elements removed from the product
• a product retiring from use

• Record
• Specification
• Drawing
• Report
• Standard

Note 1: The medium may be paper, magnetic, electronic or optical computer disc, photograph or master sample, or a combination thereof.

Note 2: A set of documents, for example specifications and/or records, is frequently called 'documentation'.

Note 3 : Some requirements relate to all types of documents, however there may be different requirements for specifications and records.

NOTE    This results in a "valid need for change" which enables the change to be effectively processed and helps to ensure that the associated configuration documentation provides a comprehensive historical record of the full lifecycle of the change.
