WE.24 Extra Time Approved? Context

The primary objectives when executing a Task are to ensure that the work is completed when scheduled, that all required outcomes, specifications and tolerances are achieved in the allocated time, and that the sustainability expectations of the Company are mete. Throughout the execution of the schedule, and the Tasks in it, a check is maintained on both the rate of progress and on achievement of the specified outcomes. If it becomes apparent that the schedule, Task outcomes or Task completion time cannot be met an assessment of potential control actions must be made. A prompt control action may create the opportunity to meet the work outcomes. There are two actions that can taken to achieve the completion of the schedule or a Task within it. One is to extend the duration of the Task(s) causing the issue, the other is to provide additional resources to accelerate the completion of the Task(s). Where the issue can be resolved by allocating extra time this is the first choice option. In some cases an extension of the Task duration may have no impact on other work (e.g. service work on a backup unit that is not immediately required for duty), however, where an extended duration may affect other work (e.g. service of a unit that is due to return to operation at the scheduled completion time) the appropriate stakeholder(s) should be consulted. If other tasks have been completed in less than the allocated time, or there is ‘float’ time in the schedule, then this time may be able to be utilised to extend a Task duration with no impact on other business areas. In this case approval of the extended Task duration is the accountability of the manager of the business area. If extending a Task duration may affect other business areas then approval of the change is the accountability of the crossover manager for the business areas. Purpose To decide if additional time should be approved to allow the completion of a scheduled work package.
