Abstract
Quantification of quality assessment criteria at the stages of design preparation of production
Incoming article date: 15.01.2026The article is devoted to the quantitative formalization of quality assessment criteria for use in an automated quality management system at the stages of design preparation of production (KPP). The article discusses the stages of a technical proposal, a draft design, a technical design and the development of working design documentation. A unified evaluation procedure is proposed for five key groups of criteria for the quality of a machine-building product: the quality of technical solutions, reliability and operability, safety, adaptability and uniformity, as well as operational properties. Grouping criteria into groups allows for an end-to-end assessment of the CHECKPOINT between the stages, which provides an opportunity for experts to conduct an assessment. For each group, a method has been formulated to obtain a final indicator that provides a comparable numerical estimate that is practically suitable for further use in an automated quality management system at the stages of the CHECKPOINT. The methodological basis of the study was the analysis of sources that make it possible to identify the most characteristic problems and requirements for quality assessment at the stages of the CHECKPOINT. The results obtained contribute to increasing the degree of formalization of the quality assessment procedure at the early stages of the product life cycle, which creates conditions for improving the quality of products through systematic and reproducible evaluation of innovative solutions. Procedures for rationing scales and setting thresholds are provided.
