Abstract: This case study presents the application of Lean Six Sigma (LSS) methodology to improve the production process of a firm that produces a home health product in the USA. The goal is to demonstrate how this process is improved using LSS methods. Define, measure, analyse, improve and control (DMAIC) is used to improve the production process in a structured manner. This includes using VSM to create a current state outline of the process and to identify needed areas of improvement, as well as utilising the five whys approach to identify the root cause of problems. It is found that applying LSS methodology led to positive results, such as improved on-time deliveries, reduced idle times, and raw materials reductions. The techniques used in this work can aid practitioners that want to learn more about making improvements at their own firms using LSS methods.
