What needs to change: a prototype ready for production, a product that costs less to make, or a quality problem resolved at its cause.
You have a prototype or design. You need to know what is ready for production, what still needs work and how to move forward.
Review the existing design and test results against the intended materials, processes, volumes and quality requirements. Focus the work on the gaps that matter.
Explore the approachYour product is already designed or in production, but it costs too much to make. Look at the design and the way it is manufactured before assuming a cheaper supplier is the answer.
Start with the product requirements, production volumes and current cost breakdown. Compare potential savings with tooling, engineering, testing and other costs of making the change.
Explore the approachYou have repeated defects, rejected batches or unstable supplier quality. You need to protect current production and make a change that prevents the problem from recurring.
Distinguish between the cause of the defect and the reason existing controls missed it. Replacing a batch may contain the immediate problem without fixing either.
