Small and Medium Industries (SMI) face challenges in ensuring product safety and quality due to the optimal implementation of Good Manufacturing Practices (GMP). This study aims to design a standard production process framework based on GMP indicators to improve the process quality in snack food SMIs. The research employs a case study approach with a mixed-methods design at a chip�producing SMI in Batam City. The DMAIC (Define, Measure, Analyze, Improve, Control) methodology was applied to analyze historical defect data, observations, and in-depth interviews. Initial measurement results showed a defect rate of 12.3% and a GMP audit score of 58%. The analysis revealed the root causes of the defects, namely the absence of SOPs, machine instability, and an unsupportive layout. The proposed solution is a framework encompassing layout modification, SOP development, training programs, and a daily monitoring checklist form integrated with GMP indicators. The study concludes that the systematic integration of GMP and DMAIC is effective in creating sustainable improvements and provides a practical contribution in the form of an adoptable model for similar food SMIs.
