Abstract: Manufacturing industries need improvement approaches that increase operational efficiency while reducing environmental impacts and protecting workers. However, Sustainable Lean Six Sigma studies rarely connect sustainability assessment, risk prioritization, and stakeholder-oriented technical solution design. An integrated framework is therefore needed to translate assessment results into improvement actions that address process risks and operational requirements. This study develops a hybrid Sustainable Lean Six Sigma framework that integrates the Risk Priority Number and the House of Quality to improve sustainable production performance. The framework follows the Define, Measure, Analyze, Improve, and Control stages. Sustainable manufacturing indicators were selected through literature analysis and focus group discussions. Indicator weights were determined using the Analytic Hierarchy Process, while overall performance was evaluated using the Manufacturing Sustainability Index. Sustainable Value Stream Mapping and the Traffic Light System identified critical indicators across economic, environmental, and social dimensions. The Risk Priority Number prioritized failure causes, while the House of Quality translated priority risks into technical improvement actions. The framework was applied to an offset printing production line. Five critical indicators were identified: production time, transportation, material use, energy consumption, and workplace safety. Evaluation of the proposed future-state design estimated a reduction in production time from 947.06 minutes to 736.60 minutes and in material transportation distance from 510 meters to 120 meters. Estimated efficiency improvements were obtained across indicators for time, transportation, materials, energy, and safety. Consequently, the estimated Manufacturing Sustainability Index increased from 78.81% to 84.49%. These findings indicate that the hybrid framework strengthens improvement decisions by combining process efficiency, sustainability performance, risk severity, and stakeholder requirements. The framework provides a structured managerial approach for prioritizing improvement actions and supporting sustainable production transformation in complex manufacturing environments.
