Method & Evidence

AimTo assess the impact of lean manufacturing techniques on productivity and layout design within the sewing section of a garment industry.
MethodComparative case study with pre- and post-implementation analysis.
ProcedureA baseline assessment of a t-shirt sewing line was conducted using time studies and process flow mapping to identify non-value-added activities. Lean techniques such as 5S, line balancing, and just-in-time were then implemented. Post-implementation analysis was performed to compare productivity metrics and identify changes.
ContextGarment manufacturing industry, specifically a sewing section.
