Skills you'll practise

• Read a Gantt-style schedule and identify overlaps, idle time and orders that will miss a cut-off

• Separate internal and external changeover tasks and plan to move external work outside the stop
• Apply frozen, firm and open windows to a rush request, and state who must approve and who must be told
