A product defect is any flaw in the manufacturing process of a product that renders it less safe or less effective than it should be. Almost all product defects can be categorized into three types:
- Design Defects- are errors in the design of a product.
- Manufacturing Defects- are errors in the manufacturing of a product.
- Marketing Defects- are flaws in the marketing, packaging, labeling, or instructions for use of a product.
