This study aims to manage requirements from critical stakeholders for the development of a novel rehabilitation device for the elbow and forearm rehabilitation using Costumer Value Chain Analysis (CVCA) and Quality Function Deployment (QFD) tools. Results are described in accordance with the engineering requirement process adapted to this case: (i) elicitation: the requirements are from primary and secondary sources supported by CVCA application; (ii) analysis: requirements were identified and prioritized by means of QFD tool (quality, product and part characteristics matrices). The association of CVCA with QFD is an innovative and successful approach of mapping critical stakeholders to identify and prioritize requirements.
