xviii Chapter I covers the introduction to the project where, after an analysis, the central idea and problem for which the project is developed is defined, focused on failures in the process that affect productivity, generating unproductive times in the metalworking area. The background of the company, the technical, economic, and social justification is also detailed, the general objective and specific objectives are defined to carry out this work, in addition to establishing the scope and methodology used in the development of the project. Chapter II describes different general concepts, methods, and tools that are used throughout the work, such as productivity, waste, continuous improvement, lean manufacturing, work sampling, Lean techniques, and others related to planning the production. Chapter III describes the substantive aspects related to the production system of the metalworking area, in this case, the manufacture of metal structures to have a clearer knowledge of the means involved in the process such as raw materials, supplies, machinery, equipment, and human resources. Chapter IV deals with the diagnosis of the process using the tools mentioned in the theoretical framework. It is a key chapter for the development of the work, because, in this, tools and techniques typical of Industrial Engineering are applied to find the various priority problems, in this case, they are mainly related to the lack of a production plan, inadequate organization of the jobs and also the delay in the cleaning process. Chapter V focuses on the improvement alternatives made based on the results obtained in the diagnosis chapter. Various alternative solutions were proposed focused on a production planning model design, reorganization of the work area (welding and cleaning section), new distribution in the welding section, and improvement in the design of the cleaning tank. In Chapter VI a technical and economic analysis of the proposal is carried out. To technically validate them, the savings of the current times were compared with the proposed times. In the economic validation, it is possible to detail the investment and the
