Mitigation of defects in products manufactured

, 2015
This paper proposes a process of continuous improvement in which some statistical tools of quality (Control charts, the Pareto diagram and the cause-effect diagram) and risk management process contained in the NTC 5254 and ISO 31000 are used. The objective is to propose a set of simple steps to reduce the defects that occur in a production system.
