As your business grows substantially, scheduling manually or with spreadsheets become impossible. It’s under such situations it becomes inevitable to use a production scheduling software to handle more / complex jobs under tighter constraints than ever.
Optimization of shop-floor requires data that is accurate.
That’s because the cycle-time “guesstimates” common in job shops don’t work with a scheduling engine, while clean, accurate routings are more accurate in a repeating-job environment, where cycle times are predictable. Finite scheduling looks at work-center/ machine capacity availability, manpower capacity (shifts), and then organizes everything based on manufacturing lead times and priorities to deliver a shop-floor order schedule for the shop to work on.
