Business, product, or service quality plays a crucial role in maintaining competitiveness in the market. In order to achieve high quality, organizations rely on various quality management techniques such as checklists, flowcharts, cause-and-effect diagrams, and the "just-in-time" approach. One of the key responsibilities of operations management is ensuring quality, and this paper uses the example of Palfinger Marine Norway AS to illustrate the importance of this process. The example demonstrates that successful quality management is a critical factor in achieving business excellence. Implementing control mechanisms and actively involving employees in the quality improvement process contribute to increased customer satisfaction, cost reduction, and optimization of business outcomes. Continuous evaluation and improvement of quality enable companies to differentiate themselves in the market, gain an advantage over competitors, and maintain long-term success. Therefore, a commitment to the quality of business, products, and services is vital for the success of companies in a competitive market environment. The application of various quality management techniques enables organizations to maintain high standards, attract new clients, and retain existing ones.
