Choose the response that fits the time horizon

When a component becomes constrained, teams often react in one of two extremes: immediate redesign or aggressive spot buying. Both can be wrong. A structured decision should consider remaining product life, certification burden, software coupling, customer approval cycles, and expected recurrence of the shortage or lifecycle event.

The BOM optimization pillar treats response selection as part of cost engineering because each path carries a different total-cost profile.

Questions that clarify the path

• Is the part strategic to future product variants or only a legacy burden?
• Would redesign eliminate multiple risks or only solve one shortage?
• How much validation, tooling, and documentation would redesign require?
• Can stock, alternate approval, or channel expansion bridge the real demand window?

Short-life or service-only products may justify targeted sourcing and controlled stock. Core platforms with repeated exposure to the same bottleneck may need redesign, especially if the affected part also drives thermal, software, or package constraints.

Use RFQ inputs to test current market availability, then compare that evidence with redesign cost and lifecycle forecast before making a program-level commitment.
