NOTE    An element is any subdivision of the PIF, the Support system or related information to which consistent reference needs to be made. Certain elements will be selected as Configuration items.

NOTE    Variations and variances will also be considered by the classificaiton process. A change priority is determined in order to enable adequate subsequent processing. Typical ways of prioritising change are: Class 1, Class 2, Major, Minor.

NOTE    The product structure is a representation of the breakdown hierarchy (product tree) from top down to the lowest level. Each level will be able to reference associated configuration documentation such as engineering models, bills of materials, specifications, software requirements, design documents, processes and operating procedures.

The fundamentals for a product structure are:

• A product comprises a single set of elements, which can be parts, materials, and proprietary items.
• Each product will have a unique product structure.
• Elements within a product structure will have both a "private view" and "public view" information linked to them which will have to be managed. Functional view (depicts parent/child relationships and is constructed to support the definition of the PIF in terms of functionality, certification,qualification, operation, maintenance and support in a auditable manner). Physical view (a hierarchical structure, depicting parent/child relationships and constructed to represent how the build of the PIF will be achieved and the impact of any change to the PIF).
• Aspects can be viewed as "As Designed", "As Planned", "As Built", "As Maintained". As Designed view holds specifications, forecasts, plans etc against high level definitions which are expanded as the PIF progresses through its life cycle. The view is initially completed when it contains how the product operates. It is maintained throughout its life cycle to reflect authorised changes. As Planned view is populated with lower level elements defining the way the PIF is to be assembled. As Built view is how the PIF as been built up to the point of delivery. As Maintained view is populated with the support information from the point of delivery until disposal. It will contain all change information.

NOTE    Example: Solution 3 to change 5 requires redesign of the interface with Item YYY, which is also subject to Change 8. Change 7 to item XXX must not be implemented unless Change 6 has already been installed.

NOTE    An implementation directive may include description of tasks, manpower, facilities, parts, kits, support equipment and money needed to apply the actual resolution. It also identifies the organization responsible for applying the actual resolution and the timetable for completion.

NOTE    This process can initiate a reassessment as a result of analysing these co-ordinated responses. The output "Potential solutions" must include the justification for the change solutions and the resulting impacts of each solution as well as a reconciliation of requirements and the various impact reports. Justification and reconciliation must be carried out for each of the potential solutions proposed.

NOTE    Arrow Note: This information may be available from the APSI and related information.

NOTE    Requirement may be met by:

• adding a task step to an existing task required for other reasons (eg to record time taken to perform a specified task)
• or by adding information collection tasks to the support engineering program, or the support solution (eg conduct a maintenance evaluation of a new product, measure and record hours run)
• or by adding embedded support capability in the product (eg health monitoring capabilities)

[1] PLCS Activity Model, 2000.

NOTE    Note 1: Information feedback includes:

• request for identification (ID) of product and support elements
• impact assessment reports
• issues
• configuration status reports
• accepted price offers
• accepted solutions
• data received as a result of operating, maintaining and upgrading the product

Note 2: In combination with other inputs to the CM process, information feedback may, after analysis, prompt the need for a change. It will also assist the process of developing a change from a valid need for change.

NOTE    Note: This includes a control to ensure that the APSI is released in a timely and appropriate manner.

NOTE    The information Management rules include:

• Policies and instructions on the management of APSI and related information specifying what information shall be recorded, utilized and archived when performing support activities.
• Information models, standards, formats, business rules, naming conventions and reference data required to achieve effective communication.
• Specification of the information to be acquired or disposed of with the product or support elements as they enter or leave the information management domain defined by the PIF scope.
• AP239 (PLCS) is part of the information rules.
• Instructions to record specific information during support activities may be included within task specifications.

NOTE    The activities defined in the model could be performed without this resource but the model was designed to reflect the use of a shared, and integrated, data environment by all participants.

The two components which provide this capability are the information technology service or infrastructure (this arrow) and the information management rules.

NOTE    This information includes:

• that arising from the maintenance of a realized product and affecting subsequent operation (for example, a power limitation pending further maintenance work)
• achieved availability or other aspects of support performance of relevance to operators
• readiness of the support system and availability of support elements and services
• limitations on availability
• any anticipated impact on operational plans from product-in-focus condition (for example, requirement to do maintenance within specific time, inability to do maintenance before a certain time, finishing early)
• responses to operator requests on operational or support problems.

NOTE    CIs that will be affected by the proposed solutions need the impact of the change assessed. This activity has two outputs:

• Request for olution and impact assessment(s)

and

• Need for revised solutions.
