Lamella defects are responsible in large part for rework losses and decrease in the quality of the finished floor. These defects increase costs, a very important factor in the process wood floor production. This work aimed to quantify and classify the common defects occurring in the lamella production, find out causes and propose solutions and improvements using the tools “Brainstorming", “Pareto Diagram", “Ishibawa Diagram", and 5W2H. 1598,47 square meters of lamella of the species Muiracatiara (Astronium lecointei Ducke), Amendoim (Pterogyne nitens Tul), Cabreúva (Myroxylon Balsamum Harms) and Timborana (Pseudopiptadenia suaveolens Miq) were sampled with the following dimensions: thickness (2.5mm and 3.5mm), width (76,2mm, 82,5mm and 127mm), lenght (450mm to 1.200mm). The most frequent defect found at the lamella production was the mark of the saw (31%), followed by the wood cut done by the supplier (23%) and the lack of work instructions (15%). The main causes to the mark of the saw were the defects caused by saw maintenance problems of the wood suppliers.
