Resumo. The objective of this research was to improve the operating procedures of control of the volume of timber estimated by the forest inventory and the effectively harvested volume in order to reduce inconsistencies in the forest planning practiced in a forestry plantation of Pinus spp. in Paraná state. Accordingly, we used the tools of quality: storming and PDCA Cycle through an exploratory research project to study together. The study showed an inconsistency initial volume – 24,73% of the volume estimated by the inventory and the effectively harvested wood. This inconsistency was composed of operational failures in the activities of Forest Inventory (+13,84%), Forest Harvesting (+15,62%) and Expedition Wood (-3,08%). The application of quality tools helped in the identification of inconsistency, as well as the revelation of operational failures, which suggested some routine monitoring and checking each of the activities involved in managing operational forestry.
