SC.04 Assign Scheduled Date and Time Context

Once the synergies and conflicts between Tasks have been determined, the Tasks must be allocated to an appropriate place in the Routine Operating Schedule (ie within the equipment/plant operating pattern or capacity distribution defined by the agreed Operating Master Schedule), and within the scheduling window (between the Earliest and Latest Start Dates) defined for the Task. Where there is flexibility in the scheduling window for the Tasks, and the appropriate operating conditions are available, the forecast of available resource (labour, special tools and equipment, services etc) capacity can also be consulted in order to achieve the best labour utilisation possible in each period. This process of allocating a Scheduled Date/time and resources to Tasks will define the draft schedule – NB all of the Schedule is considered to be ‘draft’ except the current Accepted Schedule (typically 1 schedule period agreed to at the last schedule review meeting). Purpose To allocate all approved Tasks an appropriate Schedule Date/time. Quantity One Scheduled Date (and Scheduled Time if necessary) for every approved Task. Quality In building the draft schedule the following criteria are to be considered;  all approved Work Orders/Tasks must be scheduled for completion before the Work Order Required Date,  the equipment/plant operating pattern or capacity demand for the scheduled Tasks shall, where possible, fit within the Routine Operating Schedule for the area,  the synergies and conflicts established in SC.03 should be reflected in the schedule,  provided all of the prior criteria can be met, labour demands should be kept within the forecast of labour availability,  any issue that may affect the achievement of the above criteria shall be flagged as a critical issue for the draft schedule. Time This task must be performed, for all approved and incomplete Tasks, at least once within each Schedule Period, prior to the review and commitment of the schedule.
