TRIZ Methodologies for Improving LEAN Production Processes

The application of Lean principles and tools as identifiers of improvements has become a dominant paradigm in organizations, that against of new customer requirements may be facing increasing limitations, specifically in response
times and customization. In this context, the present work aims to explore the "how" and "why" of synergies and dysfunctions between Lean practices, TRIZ tools and operational performance. Based on three case studies, a discussion is made of how TRIZ can complement the potential limitations in three different sectors of technological intensity: high, medium and low. Although the different environments analyzed (machines and electrical equipment, automobiles and food, respectively), the final results are the same, the TRIZ methodology can be considered as a promising solution to obtain significant improvements in the efficiency of the processes carried out by the company. Using a comparative
analysis, it was possible to generalize the results obtained and to define the performance behavior obtained from the association of the application of Lean and TRIZ tools. In this work is demonstrated that the methodology used is applicable to any type of organization, regardless of the type of business, sector, size or Lean applied tools.
