Nowadays, the efficiency of a company's processes and productivity are critical factors for it to stand out in its field. A methodology that has been highly effective for this purpose is Lean Six Sigma, which is based on data analysis to reduce time, eliminate waste, and enhance product quality. The objective of this study was to design and implement an improvement proposal for the operations area of a microenterprise in the alcoholic beverage sector through the tools of Lean Six Sigma. To develop the proposal, the DMAIC cycle was taken as a reference. The main problem of the company studied was the excessive amount of time that did not add value to the final product. This has resulted in a high lead time, inefficiency in the process, waste of resources, and, consequently, losses for the company. The implemented tools allowed for a 44% reduction in cycle time and a 29% increase in productivity in the operations area. The value of this study lies in the fact that the methodology and tools applied can serve as a guide for future Lean Six Sigma case studies in other micro-enterprises and sectors, benefiting researchers and professionals.
