In modern competitive conditions, product quality is becoming one of the main indicators that users pay attention to when choosing a product. Thus, it is relevant to analyse the process of forming a high-quality production strategy. The purpose of this study is to analyse the methods of forming a strategy for improving product quality based on examples of individual companies. The main research methods used in the study were: analysis, forecasting, historical, etc. The paper examines certain methods of product quality management, namely: Lean Management, Six Sigma, Theory of Constraints, and Total Quality Management. Their features, purpose of use, and implementation stages were outlined. In particular, it was shown that the main goal of Lean Management is to reduce time and costs to ensure high quality standards, while Total Quality Management is more focused on investigating customer preferences and optimising the internal motivations of company employees. Thus, it was concluded that each of the methods can be used by different companies at different times and lead to different performance indicators. This indicates the relevance and necessity of conducting separate research by the company's managers to choose the approach that will be most effective for them. In addition, the implementation of these methods in individual enterprises was evaluated, and the problems and advantages that were obtained from them were described. The conducted research brings new knowledge to the theory of marketing, and its conclusions can be used by companies in practice, for example, during the process of creating their own competitive strategy in the market
