Every topic covered so far in this Knowledge Library largely deals with one order at a time. PPC (Production Planning & Control) is the function that zooms out: deciding which orders go on which lines, in what sequence, so the whole factory's capacity is used well and every delivery date is realistically achievable — not just this order's, but every order running at the same time.
Matching the factory's total available capacity against confirmed and upcoming orders, so nothing gets overbooked.
Assigning specific orders to specific lines based on line capability, current workload, and delivery priority.
Coordinating with merchandising and stores so fabric and trims arrive in time to support the planned cutting and sewing schedule.
Tracking actual progress against the plan daily, and adjusting the plan when a line falls behind or a delay upstream threatens a delivery date.
PPC has to balance conflicting pressures: merchandising wants every order prioritised, sales wants new orders accepted, and the factory floor has a genuinely fixed capacity. Good PPC means saying no to an unrealistic delivery date before the order is confirmed, rather than discovering the conflict once three orders are already competing for the same line.
