This study focuses on optimizing production processes of a footwear company located in Tungurahua, through a time and motion study and Lean Manufacturing tools application. The most demanded product, the VCS 222 model, was prioritized. Direct observations, unstructured interviews and the process diagrams preparation were carried out to gather information on the current situation. Through the calculation of normal and standard times, the daily, weekly, and monthly production capacity was determined. Analysis of seven wastes through Lean Manufacturing revealed significant problems in the plant layout, generating excessive transportation and time waste. Therefore, a Lean Manufacturing tool selection was developed, which defined 5s as the best tool to be applied and into this application, a plant redistribution proposal was designed using the SLP methodology. As a result, the internal transportation routes were reduced by 51% and productivity increased in the following areas and preliminary phases by the established percentages: Cutting Area 19.45%, Trimming Area 12.77%, Template Assembly 34%, Location of Toe and Counterbores 6.04%, Forming, Assembly and Supply 2.78%, Assembly Area 14.16%, and Finishing Area 3.62%. Finally, instruction was developed for the production manager and operators, detailing the appropriate work method, ensuring the effective implementation of improvements. This integrated approach made it possible to optimize resources, reduce time and increase efficiency in production processes, with a positive impact on production processes
