This paper presents a decision-making systematic that orients development actions during new product development (NPD). The systematic integrates QFD (Quality Function Deployment) and FMEA (Failure Mode and Effect Analysis), helping designers to determine which quality and reliability characteristics are most important in product parts development. The systematic was created by an action-research study conducted in partnership with a company that develops air conditioning equipment. The proposed systematic provides two key contributions: (i) a modification on the evaluation of FMEA risk measures, reducing their inherent subjectivity, and (ii) the integration of these measures with parts prioritization indices from QFD matrices, providing a decision diagram for parts development. This diagram allows one to visualize the impact of each part on quality and reliability characteristics, thus aiding in the decision process concerning the essential aspects for product development. The practical results highlight the ease of applying of this method, primarily in teams with a previous knowledge of QFD and FMEA.
