SS.14 Specify Service Action Resources (Labour Materials & Equipment)

Context

A Service Strategy is a high level description of the types of action required to prevent, predict, mitigate and or correct a threat that is likely to occur.

There are six basic strategy options that may be applicable to manage a threat. These are; 1. Modification of the process – remove or reduce the threat and the need for service work. 2. Monitor process condition and/or performance to identify the best time and type of service action. 3. Initiate service actions based on a pre-defined interval or life. 4. Install back-up or containment systems to circumvent or mitigate the consequences of the threat. 5. Operate the process to the point of failure. 6. Closure of the process. Every strategy option will require at least one action to implement it. A condition monitoring strategy will require at least two actions for implementation. For example: The vibration level for a gearbox bearing may be monitored on a regular basis in order to predict the failure of the bearing – this action may occur many times over the life of the gearbox. When the vibration indicates an imminent failure of the bearing the bearing will be changed – this action may occur several times over the life of the gearbox. These actions are generally referred to as the primary and secondary actions of the strategy.

Once the service actions have been defined the details of the resources required to complete those actions can be specified.

Purpose

To specify the resource requirements for each service action.

Quantity

• One resource specification for each separate service action.

Quality

The minimum requirement for the specification of the resources for implementation of a service action is the type (quality), number and duration of: • Each labour skill, • Each material or spare part, • Each specialised tool or item of equipment.

Where components of a service action will occur at different times, or require different types, numbers or duration of resources, these should be specified as
