A design defect is a fault in the plan or outline of a product. A design defect will affect all of the products manufactured under that design because that is how it was instructed to be made. Manufactuing defects, such a missing screw or poor quality materials, can occur even though the product’s design or blueprint is fine. Something that occurred in the process of assembling the product rather than an error in the blueprint for the product would be classified as a manufacturing defect.
