Working principles
Clarity. A useful request states what is known and marks what still needs to be verified. This helps avoid treating assumptions as approved specifications.
Accountability. Selection decisions should be supported by product-specific information, the intended duty cycle and the needs of the destination market.
Technical conversations benefit from a shared definition of the application. Vehicle type, tire position, route and loading establish the context for comparing specifications. A sourcing team can then identify which documents are needed and which questions remain open before a selection is approved.
Evidence should be reviewed for the actual product and market. A quality management system and a product regulation have different scopes, and neither should be assumed to apply without checking the relevant documentation. Changes to an application or destination can require a fresh review of the specification and its supporting evidence.
