The decision: when and how much to order, not just from whom

For a metallurgical company sourcing steel scrap and nickel, cost is dominated by materials priced on international markets. In an uncertain phase, the decision that weighs on the budget is not negotiation, but when and how much to buy: timing matters as much as production efficiency.

Average cost or protection? The point that changes the choice

Comparing an optimised plan with the simplest strategy — buying month by month at the spot price — is not only about average cost. The point that matters is protection: the optimised plan mainly reduces exposure to the worst-case scenarios, the ones that blow a budget. It is a change of objective, not just of calculation.

An executable plan: lead times, warehouse, liquidity

A plan is worth something only if it is executable. Accounting for the different lead times of the two materials and the real constraints of warehouse and liquidity avoids theoretical recommendations and produces decisions you can actually put into practice.

Simulating scenarios to plan and defend the choices

Being able to simulate on the fly what happens to cost if prices move gives procurement a concrete basis to plan purchases and budget — and to defend the choices to leadership with numbers, not hunches.

How to reason about the decision: from scenario to plan

The choice is built by comparing strategies over price scenarios, measuring for each not only the expected cost but the distribution of outcomes: how much is at risk in the adverse case. Reasoning this way shifts the conversation from «how much do we save on average» to «how protected are we if the market worsens».

Technology as an enabler

Technology exists to make this reasoning fast and repeatable, not to decide for procurement. A decision intelligence platform such as WhAI compares purchasing strategies across price scenarios, respects the real constraints and measures their risk exposure — the choice stays with Procurement and Supply Chain. It starts from data already available and sits alongside existing systems.

Key takeaways

• The decision that weighs is when and how much to buy, not just negotiation.
• The best plan reduces exposure to worst-case scenarios, not just average cost.
• A plan is worth it if it is executable: lead times, warehouse, liquidity.
• Scenario simulation gives a basis to plan and defend the choices.
• The distribution of outcomes matters, not just the expected value.
• Technology enables fast comparison of strategies; the choice stays with the team.

Frequently asked questions (FAQ)

Why isn't the lowest average cost enough?

Because an attractive average cost can hide high exposure to worst-case scenarios. Protection from the adverse case often matters more than the average saving.

What makes a purchasing plan executable?

Respecting real constraints: different lead times across materials, warehouse capacity and cash availability. Without them, it stays a theoretical exercise.

What is scenario simulation for?

To give procurement a concrete basis to plan and to defend choices to leadership, with numbers instead of hunches.
