This study examines the implementation of continuous improvement at PT Mulia Boga Raya Tbk (Prochiz) during the 2021–2025 period by focusing on quality, employee turnover, sales and revenue, innovation, and customer loyalty. This research employs a quantitative descriptive method using a single case study approach, based on data obtained from the company’s annual reports and financial statements. The findings indicate that the company consistently maintained zero product recalls over the five-year period and improved its customer satisfaction score from 86.91% in 2022 to 91.80% in 2025. In 2025, the company also recorded sales growth of 19.14% and revenue growth of 19.60%. However, employee turnover increased from 9.57% in 2024 to approximately 12% in 2025. Furthermore, absolute carbon emissions continued to increase in line with the expansion of production activities. The findings indicate that continuous improvement has become embedded in the company’s organizational culture and has contributed to operational performance and customer satisfaction. Nevertheless, the company continues to face challenges in employee retention and controlling its absolute environmental impact.
