Master Production Schedule (MPS): Definition and Role in Supply Chain

Anticipating the unpredictable: the big challenge for companies

In an increasingly uncertain industrial environment, a robust MPS (master production schedule) has become essential to optimizing supply chain planning. One supplier delay or one poorly anticipated demand, and the entire chain falls out of balance.

What is the MPS?

The MPS is one of the pillars of industrial planning. It translates commercial requirements into a detailed production plan, making it possible to anticipate load and capacity over the medium term.

The MPS answers three fundamental questions: what to produce, how much, and when?

MPS and S&OP: two complementary planning levels

S&OP sets the overall direction (3 to 18 month horizon, aggregate level). The MPS turns that direction into a detailed production plan (1 to 3 month horizon, SKU/week level). The two processes feed into each other.

The benefits of a well-managed MPS

Smoother planning that strengthens supply chain performance and reliability. More agility and consistency across supply chain, finance and sales. Clear, shared decisions that improve responsiveness.

Pitfalls to avoid

Disconnecting the MPS from S&OP. Working with outdated data. Ignoring real capacity constraints. Failing to incorporate feedback from the field when updating the plan.

The Ganacos approach

Ganacos embeds the MPS in a continuous planning process: demand forecasts automatically feed the production plan, which is checked against capacity and constraints in real time. The MPS is no longer a static file. It is a living, collaborative tool connected to your supply chain.
