Single sourcing is the deliberate choice to buy a requirement from one supplier even though alternatives may exist. Buyers use it for standardization, volume leverage, integration or a strong incumbent relationship.
| Area | What to record |
|---|---|
| Decision | Document why one source creates more value than a split award and define the review point. The contract should address continuity, capacity, data, tooling and transition support. |
| Evidence | Monitor dependency, financial health, performance, alternative supply markets and the time needed to qualify another source. |
| Watch point | Single sourcing is a commercial decision. Sole sourcing arises when only one practical supplier is available. |
