WE.23 Is Extra Time Needed? 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. Purpose To decide if additional execution time will allow a schedule/Task to be completed successfully. Quantity One decision whether additional time will allow the outcomes of a schedule or Task to be delivered successfully. Quality The decision criteria to be used are:  the actual duration of work will be greater than the allocated time,  the work can be completed if additional execution time is provided. Time This task shall be performed immediately it becomes apparent that the schedule, or a Task within it, may not be completed as committed.
