Abstract:
Metalworking SMEs that produced heavy-duty spare parts often faced unstable flow, long internal travel, and rework; prior lean studies reported similar patterns in discrete manufacturing. This study addressed these challenges by integrating Systematic Layout Planning, Standard Work, and 5S in a four-month pilot. The contribution lay in a sequenced design that first redrew proximities, then codified the best-known method, and finally conditioned the workplace to sustain discipline. The model was implemented in a Peruvian SME and was assessed with before–and–after measurements. Productivity increased 35% (0.12→0.162 units per labor hour), defect rate fell to 3% (from 8%), and internal transfer time decreased 69% (28.1→8.8 minutes per unit). These effects suggested operational stability, safer supervision, and a low-capital path to competitiveness for small shops serving heavy industries. The findings invited replication with multi-site, longer-horizon designs and simulation aided appraisal of layout alternatives. The study invited work that examined further the financial and environmental impacts.
