What Is Production Planning & Control (PPC)?

The function that plans the whole factory, not just one order at a time.

Running a Factory, Not Just One Order

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.

The Core Responsibilities of PPC

Capacity Planning

Matching the factory's total available capacity against confirmed and upcoming orders, so nothing gets overbooked.

Line Loading

Assigning specific orders to specific lines based on line capability, current workload, and delivery priority.

Material Planning

Coordinating with merchandising and stores so fabric and trims arrive in time to support the planned cutting and sewing schedule.

Production Monitoring

Tracking actual progress against the plan daily, and adjusting the plan when a line falls behind or a delay upstream threatens a delivery date.

Why PPC Sits at the Centre of the Factory

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.

Good PPC vs. Poor PPC

Signs of Good PPC

  • Line loading plan updated regularly and visible to all departments
  • Delivery dates set based on real capacity, not just sales pressure
  • Early warning given when a delay threatens a shipment date

Signs of Poor PPC

  • Multiple orders competing for the same line with no clear priority
  • Delivery dates promised without checking real line capacity
  • Delays discovered only when a shipment date is already at risk
