A second supplier is an option only when it is ready
Questions to ask before treating an alternative source as a practical continuity plan.
A name on a supplier list is not the same as an available alternative. If continuity matters, work through what would need to happen before another supplier could deliver acceptable product.
Check the path to qualification
Does the alternative have the current specification? Have samples been reviewed? Are tooling, testing, and documentation requirements understood? Record the remaining steps and who owns them.
Estimate qualification time separately from production lead time. An alternative may be capable in principle while still being unable to help within the time available.
Understand shared dependencies
Two suppliers can still depend on the same material source, production region, transport route, or subcontractor. Ask which dependencies matter for your particular product and what evidence is available.
The aim is to understand the limits of the alternative, not to assume that adding another supplier removes risk.
Keep the option current
Specifications change. Capacity changes. Commercial terms expire. Decide how often to revisit your alternative and whether a sample order or other engagement is appropriate.
For each critical item, keep a practical record: the current supplier, the alternative, the remaining qualification steps, the expected activation time, and the date those assumptions were last checked.
