This article deals with the problems related to the development of design and evaluation thereof in the industrial design of Latvia. It has been detected that evaluation parameters and common methodology, which would result in optimal assessment of a design product, have not been developed. This article also deals with the evaluation criteria of products already developed and used in the USA. Pareto principles and Pareto optimality are also examined. It is recommended to develop specific parameters for the assessment of a design product and to use the Pareto method for summarisation of results, as well as to use part of the finalised parameters already developed in the USA.
