SC.19 Modify Scope or Cancel Work Context

The draft schedule must deliver the completion of every Work Order prior to its Required Date, regardless of any apparent constraint from workplace or resource availability. While every effort has been made to optimise the draft schedule, and to remove constraints on its completion, there may still be critical issues that will prevent the schedule being completed unless they are managed. There are three basic types of critical issues;  A resource (material, service or specialised tool/equipment) that is necessary for the completion of the schedule cannot be made available at the Scheduled Date.  The schedule cannot be completed without changes being made to the Routine Operating Schedule (ROS).  The schedule cannot be completed without changes being made to the labour available for executing it. This Task Assignment applies when the draft schedule identified one or more of the above critical issues and it has been decided by the accountable manager that;  a resource cannot be available at the Scheduled Date,  that the ROS will compromise the scheduling of some work before its Required Date,  labour availability will compromise the scheduling of some work before its Required Date. In this case, the deferred completion of high impact work may produce a n this case, the deferred completion of high impact work may produce a sustainability (ie dealing responsibly with safety, the environment, employees, communities, governments and asset life), output or cost risk. If all other options have been considered, and there is no alternative to delaying the completion of some work beyond the Required Date, then the risks arising from the delay (including the residual risk after changing operating methods or parameters) must be accepted by the accountable manager. It is possible that all, or only part, of a work package may need to be delayed because it cannot be accommodated in the schedule. After the decision has been made to accept the risk of delaying the work, the components of the work that are to be delayed, and the date/time to which they may be delayed must be specified. Where only a portion of the work is delayed it may also be necessary to modify the work package. It is also possible that the delay of a Task may render it unnecessary – for example a weekly inspection that is missed will not need to be rescheduled. If a work package, or part of it, may need to be modified or cancelled this should be done in accordance with the Work Approval process.
