SC.07 Are changes to Routine Operating Schedule or Resourcing Required? Context The objectives of work scheduling are firstly to ensure that all Tasks are completed at the right time, and secondly to make the most efficient use of resources while doing this. Every work package has a distinct window that defines the right time for scheduling. This window is bounded by the earliest date that all requirements for completion of the work can be assembled (the Earliest Start Date), and by the latest date by which the work must be started (the Required Date less the work duration = Latest Start Date). The draft schedule must deliver the completion of every Task so that each Work Order is completed prior to its Required Date, regardless of any apparent constraint from workplace or resource availability. If the draft schedule indicates that either changes to the Routine Operating Schedule (ROS) or changes in the available resources are required in order to complete all Work Orders by their Required Date then one of two options exist;  the schedule has not been optimised and some Task(s) may be able to be moved to another Scheduled Date and time where it will not create the need for changes to the ROS or available resources but will still meet the Work Order Required Date, or  the need for changes to the ROS or available resources is a critical issue for delivery of the schedule and must be escalated to the appropriate authority for a decision. Purpose To check that the ROS/resource demands of the draft schedule are within the available capacities. Quantity One decision whether or not the draft schedule fits within the constraints of the ROS and forecast of available resources. One list of ROS or resource critical issues, with possible actions to deal with them. Quality In making this decision consider the following criteria;  the operating/downtime or capacity forecast of the Routine Operating Schedule,  the operating/downtime or capacity demand of the draft schedule ,  the forecast availability for resources,  the resource demands of the draft schedule,
