Direct materials with a split award

Move from an RFQ to a reviewed supplier allocation and contract.

The problem

A materials purchase may exceed one supplier's capacity or require a balance between cost and delivery performance. A spreadsheet can show individual offers while hiding whether the full allocation meets capacity and contract commitments. The cheapest line is not necessarily a feasible award. The buyer needs a view of the whole volume and a way to explain why the proposed split fits the business rules.

A split award also creates work after the decision. Suppliers need clear quantities, delivery expectations and contract terms. Before collecting offers, agree which items can be split and which must stay together. Decide whether supplier eligibility is a mandatory gate. This prevents a low weighted score from compensating for a failure to meet an essential specification.

How the workflow runs

Create an RFQ with item specifications, quantities, units, delivery requirements and the response deadline. State which evidence supports quality and ESG evaluation. Invite eligible suppliers through the sourcing workflow. Give them a consistent response structure so the buyer can compare like with like. Handle clarification questions through a shared process and keep revisions available to everyone who needs to respond.

Collect offers and check completeness before optimization. Confirm prices, capacity and lead times with suppliers where the response is unclear. Add the award constraints: capacity limits, minimum or maximum shares, contract commitments and budget. Set the criteria weights and explain the scoring method. Run the optimizer on those inputs. If no feasible result exists, review the conflicting rules rather than quietly dropping one.

Compare the recommended allocation with alternatives. Use what-if scenarios to examine a changed capacity or a different weight setting. Discuss practical delivery and quality implications with the people who will use the materials. Verify the selected quantities with suppliers before recording the award. Carry the agreed allocation and terms into the contract so the sourcing decision remains connected to the purchasing commitment.

Modules and preparation

This workflow uses RFQ, supplier offers, the split-award optimizer, award decisions and contracts. LP can suit divisible volumes. MIP can represent discrete choices where the configured model supports them. Ask whether package sizes and minimum order conditions are represented before treating a result as ready for ordering. The model must describe the purchase you actually intend to make.

Prepare a clean demand file, supplier eligibility records, comparable offers and evidence for non-price scores. Bring existing contract commitments and an agreed cost basis. Choose an owner for each input and record changes made during review. The useful output is a decision that buyers can reproduce and challenge, with quantities and assumptions that can be carried into the contract.

Checklist

  • Confirm which volumes can be split.
  • Collect comparable offers and capacity evidence.
  • Document weights and mandatory requirements.
  • Check existing contract commitments.
