Knowledge & Design Reuse

Knowledge & Design Reuse is the cheapest engineering productivity gain on the table — the part you don’t design, qualify, source, or stock costs you nothing. Industry surveys repeatedly show 30-70% of “new” parts in a typical PLM database are functional duplicates of existing parts. Every duplicate carries its own qualification cost, supplier overhead, inventory stock, tooling, and obsolescence risk. The cumulative drag is one of the largest hidden costs in any engineering organization.

PLM attacks the problem with Classification Schemas, Metadata Management, geometric search, and parametric libraries — making prior art findable in seconds so engineers can lift instead of re-create. Validated simulation models, test reports, and templates ride along the same backbone.

Business benefits

• Cost: every avoided new-part-creation removes its qualification, tooling, supplier-onboarding, and inventory cost — typically thousands of dollars per part across the lifecycle.
• Speed: reusing validated CAD, simulation, and test artifacts collapses design cycles versus clean-sheet equivalents.
• Quality: mature, field-proven parts and models carry lower escape risk than new designs by definition.
• Margin: higher per-part purchasing volume on standardized parts unlocks better supplier pricing and quality tiers.
• Risk: fewer unique parts means fewer end-of-life events to chase and a smaller obsolescence-management surface.
