Automotive supplier products are often complex, but complexity is rarely why OEM decisions stall. OEMs hesitate because they are balancing risk, integration effort, and internal accountability.

You are not selling to one person. You are selling into a group that carries shared risk. Engineering wants confidence in performance and integration. Procurement wants confidence in cost, supply, and long-term exposure. Programme teams want confidence in timing and support. Quality teams want confidence that you have done this before and will still be there when something goes wrong. And none of them want to be yelled at for picking the wrong product.
