Goldratt, has emerged as a tool for achieving competitive advantage. Many researches also focused on the application of lean thinking developed by Toyota and proposed by Ohno. This philosophy has been proven to be effective in several production processes. This paper aims to propose a method of problem solving through the integration of theory of constraints thinking process and the principles of lean production. As a tool for problem identification, the method defends the use of current reality tree and, to solve problems, the lean thinking tools, proposed by Picchi. The developed method was implemented in a contractor. The research methodology was research-action. Among the results, there was a realistic diagnosis about the core problems in company. According to this, the core problem of the contractor is “the lack of commitment of manpower” that results in the main problem “the financial loss”. The principle of perfection was verbalized as a proposal to solve the problems and the tools to be implemented for solving problems were “commitment of senior management to employees” and “simplicity in communication”.展开更多

The lean thinking proposed by Taiichi Ohno and developed by Toyota Company has been tested and found effective in several production processes. This paper aims to propose a method of problem solving through the integration of the principles of lean thinking and the TPTOC （Thinking Process of the Theory of Constraints）. The method was implemented on a civil contractor, using the research methodology and the action research. We concluded that, after the research, the core problem regarding the company is the technical failure of the administrative staff, which causes delay in the construction works and financial loss. We also concluded that the obstacles that could prevent the achievement of objectives are related to lack of a vision from senior management regarding financial return when investing in employee training. The goal was accomplished with the integration of two philosophies, TPTOC and lean. And only the tools proposed by Fl^vio Augusto Picchi were not enough for executing the action, so new lean actions were verbalized.展开更多
