Resumo
Tendo como base o reconhecimento que os métodos Teoria das Restrições (theory of Constraints - TOC), Produção Enxuta (Lean Production - LP) e o Seis Sigma (Six Sigma - SS) possuem características complementares que podem potencializá-los quando utilizados em conjunto, algumas empresas relatam experiências de aplicação concomitantes destes método. Entretanto, o desafio de obter melhores resultados levaram pesquisadores e profissionais a buscarem melhores soluções, resultando, entre outras, em iniciativas de integração. Conhecidas como Integração TLS, estas iniciativas vêm procurando encontrar soluções que permitem compatibilizar características muitas vezes conflitantes entre elas, encontrando um modelo que as unifiquem. O objetivo prinicpal deste trabalho é realizar uma pesquisa de cunho fundamentalmente teórico que investigue tais modelos, avaliando suas características e identificando como tal integração foi viabilizada. A pesquisa teórica é complementada por uma pesquisa de campo com a aplicação de questionários para os autores dos modelos de integração, para as empresas que realizam a implantação dos modelos de integração e para as empresas praticantes da Integração TLS. Esta pesquisa foi direcionada para avaliação dos cinco modelos existentes de Integração TSL, não considerando eventuais integrações com outros métodos de gestão. Também se buscou encontrar na literatura relatos de casos de aplicação destes modelos. Cinco modelos foram identificados, nos quais se constatou que a base de todos eles é a proposição de um proposição de um processo focalizado de melhoria contínua, com papeis bem definidos para cada método que os constitui. Ao final da pesquisa teórica e pesquisa de campo é proposto um modelo de Integração TLS, concretizando as etapas do método de pesquisa de desenvolvimento teórico conceitual
Based on the recognition that the methods Theory of Constraints (TOC), Lean Production (LP) and Six Sigma (SS) have complementary characteristics that can empower them when used together, some companies report these experiences concomitant application method . However, the challenge of getting better results led researchers and practitioners to seek better solutions , resulting, among others, in integration initiatives. Integration known as TLS, these iniatives are seeking to find solutions to reconcile often conflicting features between them, finding a model that unify. The main objective of this paper is to research largely theoretical slant to investigate such models, assessing their characteristics and identifying how such integration was made possible. Theoretical research is complemented by a field survey with questionnaires to the authors of integration models for companies that perform the deployment and integration models for business practitioners Integration TLS. This research was concluded to evalue the five existing models Integration TLS, without considering future integration with other management methods. We also sought to find in the literature reports of applications of these models. Five models were identified, of which it was found that the basis of all of them is the proposition of a focused continuous process improvement, with well-defined roles for each method that is. At the end of the theoretical research and field research is proposed a model of integration. TLS, implemeting the steps of the method of theoretical conceptual development research
