Once a proposal has been approved, it is necessary to create the Scheduling Blocks that will be used to run the observations at the telescope. The SBs are automatically generated from the information contained in the Science Goals by observatory staff - this is no longer a task for the PI. Observatory staff can also build SBs from scratch, or edit what generation has produced. SB generation continues to be improved and in most cases can be relied upon, but special observing modes often require manual intervention.
