Maintenance Work Definition Structure
A maintenance work definition defines the maintenance process in an organization. It includes the item structure, routing operations, and resources that are needed to perform the maintenance or repair activity.
A maintenance work definition consists of the following elements:
-
Operations
-
Operation Items
-
Operation Resources
The work definition's operations are executed following a linear path based on the operation sequence. A work definition must have at least one operation and it must be associated to a work center. You can either use predefined standard operations or you can manually define and enter each of the operations. We recommend you create and use standard operations wherever possible, allowing them to be reused across different work definitions.
Typically for asset maintenance, each operation is defined as including a count point. This means that the operation is expected to be executed by a technician, indicating they have completed each of the steps of the operation. During this time, any additional material, resources or meter readings can be entered.
Alternatively, if an operation isn't indicated as a count point or an automatically transact operation, then it's considered as an optional operation. In this case, there's no action required by the technician during execution of the work order. This capability is available, but typically not utilized for most maintenance work order operations. However, there may be some cases where common tasks that don't require manual reporting can be modeled without any count points, thus they will automatically be completed once the work order is released for execution.
Operations
The work definition operations define the sequence of steps to be performed in maintaining an asset. The operations are executed following a linear path based on the operation sequence. You can also define operations that can be resequenced during work execution. A work definition must have at least one operation. An operation must be associated to a work center. You can either use standard operations, or you can manually enter the operations. If an operation isn't indicated as a count point or an automatically transact operation, then it's considered as an optional operation.
Operation Items
The operation items define the material requirements for operations. The components of the item structure of the asset are assigned to the operations where they're required. You can also assign existing items to operations, and these are considered ad hoc items. This functionality requires the Override Item Structure Components in Work Definition privilege.
Operation Resources
The operation resources define the resource requirements for operations. The pool of resources available comes from the work center assigned to the operation. A resource represents either a labor or equipment that adds value to the maintenance process.
