Key Takeaways Design for manufacturing (DFM) is not a final engineering check. Cost, materials, process, tooling, tolerance, and appearance are linked from the first design decision, and treating DFM as a late gate is how expensive tooling and unsourceable materials get locked in. A design is the combined result of competitor products, end-user experience, trends, […]

Key Takeaways A go-to-market checklist belongs in the same weekly meeting as the engineering review, not after it. By the time the product is on a vessel, most launch decisions are already locked. The checklist exists to hit 3 numbers: strong first-order demand, a stable average selling price, and a reorder placed before the first […]

Key Takeaways Amazon does not inspect product quality on inbound FBA shipments; it enforces prep and labeling requirements and acts on defect metrics after customers complain Once inventory is checked into a fulfillment center, the seller cannot inspect, sort, or rework it without a removal order The only window to fix a defective batch at […]

Key Takeaways AQL (Acceptable Quality Level, or Acceptance Quality Limit) is an acceptance-sampling standard used to determine whether a production lot meets an agreed quality threshold by inspecting a sample rather than every unit. The sample size and accept/reject numbers come from standardized tables in ANSI/ASQ Z1.4 and ISO 2859-1, not from the factory’s judgment […]

Key Takeaways Contract manufacturing in China works when a product has finished specifications, a realistic order volume, and defined quality standards, and becomes risky without them Vetting a factory means more than checking a business license. It requires a physical or remote audit and a pilot run measured against written acceptance criteria IP protection comes […]

Key Takeaways Product creation is a sequence of validation, design, and manufacturing decisions, not a single creative leap from idea to shelf Skipping market validation is the most common reason early product development stalls after money has already been spent Decisions made during concept and design carry through to manufacturability, and get more expensive to […]
