NOTE    Consists of predicted product failure or degradation, safety drivers (legal and others), environmental drivers or operation and readiness drivers.

Also includes requirements for tasks to collect the information needed to assess support performance.

[1] PLCS Activity Model, 2000.

NOTE    Support elements include:

• Repair parts, which are the physical items that become part of the equipment during the equipment's life. Repair parts are either expendable or repairable as they are replaced during the equipment's life.
• consumable items, which are the physical items that are consumed by the equipment as part of delivering its designed capability, but do not become part of the equipment
• support tools and diagnostic and test equipment, which are required to undertake support tasks
• trained people

In this activity model fixed support infrastructure is shown as a resource.

[1] PLCS terminology dictionary, 2000.

NOTE    Possible states include:

• consumed
• in-use
• available to re-locate

[1] PLCS Activity Model, 2000.

NOTE    May use AP233.

[1] PLCS Activity Model, 2000.

NOTE    It includes:

• a resourced schedule to develop and monitor the performance of one or more support solutions
• task specifications and other documents related to the schedule specifying the policies and processes to be used in conducting such activities.

NOTE    Support feedback is generated when tasks are performed on a product needing support. It includes information on:

• the operation, usage and location of the product or support element receiving support
• the current configuration of the product or support element
• the condition of the product or support element receiving support, before, during or after the support activity, recorded as properties, states or observations
• the progress and status of work
• the resources used to perform work
• issues arising from work done, including proposals for change to the product or support solution

[1] PLCS Activity Model, 2000.

NOTE    Support impact on design includes influence on the product design (from the support perspective) and plus statements of requirement for the design of support items.

[1] PLCS Activity Model, 2000.

[1] PLCS terminology dictionary, 2000.

NOTE    Note 1: Requirements to capture specific information may be included in task procedures.

Note 2: This activity model assumes that:

• the support information management rules include the use of AP239 to structure the Assured Product and Support Information and the collection of feedback as Related Information.
• the support information management rules apply to all elements of the PIF and its support system. Where this is not the case, appropriate interfaces will need to be negotiated to link the AP239 information set to related, non-compliant information.

NOTE    Support opportunities may have dates, time and location. They may also have priorities and readiness requirements. Support opportunities may apply to any combination of operational products, parts of product, and to support elements. Support opportunities may arise whilst the operational product is in use.

Example: Ship on passage.

[1] PLCS terminology dictionary, 2000.

NOTE    Includes which realized products or support elements will be available, for how long, at what location (or possible locations) and under what conditions.

It may also specify the planned future usage of the product or support elements to assist identification of necessary tasks.

[1] PLCS Activity Model, 2000.

[1] PLCS Activity Model, 2000.

NOTE    Examples:

• when operating
• a base maintenance period
• an annual inspection
• major refit

[1] PLCS Activity Model, 2000.

NOTE    A support plan may include a presentation of a typical maintenance program for a product needing support.

It may also specify non-maintenance tasks, such as activities required to provide and prepare required resources.

Some necessary tasks may never be implemented if the conditions under which they would fall due, fail to arise (eg a task to correct a rare fault state).

NOTE    The prediction of some metrics may require assumptions to be made about resource availability and delay times.

[1] PLCS Activity Model, 2000.

[1] PLCS Activity Model, 2000.

NOTE    The status of the schedule will change as it develops.

The support schedule may include a maintenance schedule defining work to be performed on the product needing support. A support schedule may also define tasks applicable to support elements or required resources (eg calibrate a test instrument).

[1] PLCS Activity Model, 2000.

NOTE    The support solution may include:

• a listing of relevant support drivers
• a support plan, that identifies necessary tasks to respond to these support drivers, and specifies the conditions under which each task falls due
• justification for the above
• task procedures for necessary tasks
• identification and quantification of resources needed to achieve necessary tasks, including types of person with skill level
• resource models for necessary tasks
• identification of the deployment environment and requirements for which the support solution was designed.

[1] PLCS terminology dictionary, 2000.

NOTE    The requirement may include specified performance metrics for the support solution, with threshold or other tolerance values, defined in terms of agreed support characteristics.

May use Application Protocol 233.

NOTE    Note 1: Symptoms

• are the means by which faults are detected
• may be observed without knowing which anomaly caused it
• may indicate that a particular failure, or failure mode, has occurred but different anomalies, or combinations of anomalies, may cause the same symptom (effect)

Note 2: The diagnostics process is used to link symptoms to anomaly.
