Abstract—The demand for footwear in Peru has increased
significantly in recent years even though domestic production
has decreased, on the other hand, it has been shown that imports
have grown substantially. This shows that the domestic sector
has difficulties in offering good quality products, which is
directly related to low productivity and lack of innovation. In
this sense, an integral Lean-SLP model is proposed based on the
combination of tools such as total redesign of facilities, 5s,
process standardization, work design, and Jidoka to improve the
current productivity of 0.56 generated by deficient and nonstandardized
processes. The model was validated through arena
software where a cycle time reduction of 42.95% and a
productivity increase of 22.5% were obtained. This proposal
allows SMEs in the footwear sector to be more competitive in the
foreign market by producing shoes of higher quality and
therefore better acceptance.
