This research work is an initial path towards a significant improvement in productivity, efficiency, lead time and waste in Peruvian enterprises that must to improvement production and efficiency, increase productivity and eliminating wastes to reduce total production cost. This paper presents a case study of a micro enterprise dedicated to the manufacture and assembly of wooden desks that are distributed to the regional and national market. Process times were taken to determine baseline indicators using the O-T diagram. The 5S methodology was implemented to reduce search times for materials and tools and movements of operators. Activities were grouped that allowed reducing downtime and increasing production. In this sense, production flow was optimized thus reducing non value added activities. The results showed that reducing waste time, would enable the enterprise to improve production.
