Abstract
The latest years have witnessed an increased demand for adopting continuous improvement methods and concepts. Lean Six Sigma is a real example that has proven its effectiveness in industrial and service sectors. This article will be the subject of a Lean Six Sigma application within a Moroccan SME specialized in cookie production. This application has followed the DMAIC approach to improve its performance and the quality of its products. Through Lean Six Sigma, the company improved the scrap rate by 6% and operational efficiency by 5.6%. Several results are presented in the article by introducing the set of Lean Six Sigma tools deployed. The article also discusses the application limits especially related to SMEs, and the effectiveness of the results, which has been influenced by the appearance of Coronavirus either for the investment or the project progress.
