The quality is described by eight dimensions characterizing, in various respects, the data of good and determining their essence and purpose, i.e.:

  • functional features of the product, usability in accordance with the characteristics of the essence of the object,
  • features that complement the basic functional features of the product,
  • reliability, ability to work trouble-free,
  • practicality, adaptability of the product, ease of use and maintenance,
  • compliance with the standard requirements,
  • durability, the possibility of using the product for a limited time,
  • aesthetics, product reception,
  • perceived quality, closely related to the product's brand and supplier's reputation.

Fig.1. Types of quality parameters

The quality parameters are determined by the actual condition of the company and its surroundings as well as the properties of raw materials and the technological process used during production. Improperly used technologies, inadequate environment of production processes, poor storage and transport may negatively affect product quality. These parameters can also be divided according to the group of features that contain a specific number and type of detailed qualitative characteristics depending on the needs to be met. These are:

  1. Natural and technical features, all product features given to them by nature or obtained as a result of technological processes, according to standards containing basic parameters of structure and function of these products. This group consists of physical, chemical and biological distinctions). They have an objective character, because they can be compared with existing patterns.
  2. Economic features are elements of the quality structure of goods that give users a measurable sum of benefits. Expressed using economic indicators, e.g. depreciation.
  3. The functional features make the products able to satisfy material (technical) as well as intangible (brand image, i.e. branded product) consumer needs. These are, for example, durability, ease of use and maintenance, comfort in use.
  4. Ergonomic properties, adjustment of products to anatomical, physiological and psychological features of a human being.
  5. Aesthetic features that characterize the appearance. They are shape, colors, external construction solutions.
  6. Ecological features, determined by the properties of goods, making them environmentally friendly.
