The method of checking against set specifications is a direct approach to assessing a product's quality. This process involves evaluating the product's features, performance, and durability based on predefined standards and requirements. Specifications typically include technical and functional attributes that the product must meet to be considered acceptable. This testing ensures that the product is reliable, meets customer expectations, and is fit for its intended use.

In contrast, conducting focus groups is primarily about gathering consumer opinions and insights but does not directly assess the product's quality. Performing market research focuses on understanding consumer behavior and market trends rather than evaluating product specifications. Adjusting marketing strategies involves altering how a product is presented or sold based on market feedback, which again does not assess the product's intrinsic quality attributes. Hence, checking against set specifications stands out as the most objective and effective method for testing quality.
