The competitiveness and the increasing importance of delivering products of high quality made it necessary the creation of a method that addresses most of the challenges that an organisation face: Lean Six Sigma. However, the risk associated for all types of industries is augmenting and making projects under uncertain conditions has never been so difficult. Vestfrost Solutions is a manufacturer of refrigerators that already implements the Lean Six Sigma principles, although the company is facing issues in the production of one refrigerator, which quality costs are considered too expensive. The purpose of this report is to see how Risk Management can be applied with Lean Six Sigma to improve the performances of a project. The project follows the DMAIC methodology to study the production line and propose improvement actions. A decision-making tool has been developed as an improvement action. Furthermore, the uncertainty associated has been assessed. The Risk Assessment is performed in order to encourage wise decision-making. Thus, the improvement action has been evaluated after the Risk Management improvements to observe the evolution on an impact-ease graph. This paper concludes that Risk Management is an applicable approach for the organisation to robustify the outcomes of the Lean Six Sigma process and reduce quality costs.
