Production and supply plans

As explained in Demand Forecasting Best Practices

A supply plan specifies planned production, purchasing, and shipment quantities and coordinates the resulting logistics flow.

What should a supply chain produce, buy, and ship? A supply plan answers this operational question and coordinates the resulting production and logistics flow. It combines demand forecasts with constraints such as inventory targets and logistics capacity. section 2.2.2

A supply plan is not a demand forecast. Forecasts estimate expected customer demand without assuming inventory availability; supply plans translate that information into action. They can therefore differ substantially from both demand and eventual sales. section 2.2.2

An ice-cream supply decision

A planner may forecast demand for 10 pieces, plan to supply 15 as protection against uncertainty, and sell only 8. The figures 10, 15, and 8 represent forecast demand, planned supply, and actual sales—not interchangeable measures. section 2.2.2

Keep the plan responsive to changing information:

• Update short-term forecasts even when supply plans are temporarily frozen. section 6.2
• Increase the current order when a revised future forecast requires it; changing M2 demand from 75 to 100 pieces calls for 25 additional units. section 6.2
• Treat the forecast as underlying information and the supply plan as the intended action: what to buy, produce, or move. section 6.2

How Demand Forecasting Best Practices covers it

How deep it goes

Defines the plan, distinguishes it from forecasts and sales, and demonstrates forecast-driven order updates without detailing planning algorithms.

Examples

Uses an ice-cream forecast example and a 75-to-100-piece M2 revision to illustrate supply quantities and order changes.

What it assumes

Assumes demand forecasts and introduces their distinction from supply plans, sales, financial budgets, and sales targets.

What you can do after

Apply revised forecasts to adjust orders and improve mid-term supply decisions, even when immediate supply actions remain frozen.

How it connects

Links demand forecasting with inventory targets, logistics constraints, purchasing, production, shipments, sales, and financial budgets.
