Scope

The following are within the scope of this Data Exchange Specification (DEX):

Information that is used to define the message that performs the transmission of the plan information between the source and destination UK_Defence processes.
The identification, naming, versioning and status of the plan.
The plan type.
The dates defining the effectivity of the plan.
The justification for the existence of the plan, such as to prevent or to rectify a failure, to implement a change, to comply with a requirement or to rectify a health hazard.
The purpose of the plan.
The context for which a plan was developed and to which it applies.
The identification, naming, versioning and status of the tasks within the plan.
The description of how each task shall be performed, including reference to legal, health and safety advisories.
The representation of the decomposition of the plan into tasks and the tasks into sub tasks.
The representation of the sequence / precedence constraints between tasks and sub tasks.
The justification for the existence of each task, such as to prevent or to rectify a failure, to implement a change, to comply with a requirement or to rectify a health hazard.
The specification of when each task should be executed, such as a planned maintenance interval/usage limit being reached, or a condition or failure being observed.
Identification of the product to which each task applies.
Identification of the intended support levels at which the task may be performed, such as on equipment, on bench, at a maintenance depot.
Identification of the depth of maintenance that the task is classified as.
Specification of the required state of the product prior to task execution.
Specification of the expected result of performing each task, such as the state of the product.
Specification of the reporting requirement after the execution of each task, such as reporting on new product configuration, repair time, resources used and consumed.
Reference to the context (deployment environment and support concept) for which each task specification was developed and to which it applies.
Identification of the resources required to execute the plan, including material resources (spares, test equipment etc), skills, personnel, facilities, utilities and related information resources such as drawings, documents or procedures. Resources may be required to execute the individual tasks or they may be rationalized and applicable to the plan as a whole.

The following are outside the scope of this Data Exchange Specification (DEX):

Establishment of support drivers.
Specification of the actual organizations that can undertake the plan and perform each task within it.
Specification of schedules that implement the plan through execution its tasks on specific dates.
Recording of the execution of tasks.
Identification of the mechanism for reporting the suitability of the task and support solution (e.g. It needed more people, different skills, more resources, different tools).
