The organoleptic method of assessing the quality of consumer goods is based on information received from the senses, such as sight, taste, smell and touch. It allows you to assess the appearance of the product, the uniformity of color, smell and taste characteristics, brightness, contrast and saturation.
This subjective method is used in cases where other methods or specialized instruments such as microscopes or microphones cannot be used. Experts with high sensitivity and skills to analyze the organoleptic characteristics of products are invited to perform the assessment.
Traditional method
This approach involves determining the values of quality indicators by employees of experimental and calculation departments, such as laboratories, design departments, testing grounds and test centers. Research is carried out under conditions that are as close as possible to the actual use of products.
Expert method
In this case, experts make a decision chinese overseas british data package as a result of questionnaires, discussions and idea generation. This method is subjective, since the results depend on the qualifications, professionalism and experience of specialists.

Methods for assessing the level of product quality
These approaches are based on comparing the properties of the assessed product with a certain standard. We are talking about a sample - a product of the same class, in which modern scientific and technical solutions are implemented. As such an object, a hypothetical ideal product or an existing product of competitors, which is recognized as perfect from a technical point of view and is in demand on the market, can be used.
Product quality assessment is a process that includes several stages: selection of key quality parameters of the object under study, determination of their values and comparison with reference ones. The calculation of the quality level is carried out using the formula:
D = Q\Q 6
where Q is the value of the quality indicator of the product under study, Qб is the reference value.
