Lean, Six Sigma and TOC comparison (2)

Lean, Six Sigma and TOC comparison (2)


Dave Nave published an interesting article “How to compare lean, six sigma and Toc”, “Quality Progress, 03/2002”. Ten years ago, this article pointed the importance to focus on the “primary and secondary effects” of the philosophies of methods. Don’t you think that the major obstacles to improvement can effectively be addressed using System Thinking (management theory, formal and informal policies, measurements systems, rewards, values,…) ?

ST will guide you to understand what to improve and for which purpose. Lean or Six Sigma guide us to improve the system and the processes the right way in function of the context and the problem to solve.

Comparaison du Lean, du Six Sigma et de la Théorie des Contraintes (2)

Dave Nave a publié un article intéressant sur le sujet " How to compare lean, six sigma and Toc”, “Quality Progress, 03/2002”. Il y a déjà dix ans, cet article insistait sur l'importance de se concentrer sur les «effets primaires et secondaires» des philosophies des méthodes. Il énumérait certains des obstacles majeurs à l'amélioration de la performance. Ne pensez-vous pas que ces obstacles peuvent efficacement être abordés à travers une approche systémique (la théorie de management, les politiques, les procédures formelles et informelles, les systèmes de mesure, les systèmes d’évaluations et de récompenses, les valeurs, ...) ?

La systémique nous guide pour comprendre ce qu'il faut améliorer et dans quel but. Le Lean ou le Six Sigma peut nous guider pour améliorer de la bonne manière notre système et nos processus en fonction du contexte et du problème à solutionner.

Abstract of the paper  :

“The lean enterprise system, total quality management, six sigma, theory of constraints, agile manufacturing, and business process reengineering have been introduced as universally applicable best methods to improve the performance of enterprise operations through continuous process improvement and systemic planned enterprise change.
Generally speaking, they represent practice-based, rather than theory-grounded, methods with common roots in manufacturing. Most of the literature on them is descriptive and prescriptive, aimed largely at a practitioner audience.
Despite certain differences among them, they potentially complement each other in important ways. The lean enterprise system, total quality management and six sigma, in particular, are tightly interconnected as highly complementary approaches and can be brought together to define a first-approximation “core” integrated management system, with the lean enterprise system serving as the central organizing framework. Specific elements of the other approaches can be selectively incorporated into the “core” enterprise system to enrich its effectiveness. Concrete theoretical and computational developments in the future through an interdisciplinary research agenda centered on the design and development of networked enterprises as complex adaptive socio-technical systems, as well as the creation of a readily accessible observatory of evidence-based management practices, would represent important steps forward.” Kirkor Bozdogan, Center for Technology, Policy and Industrial Development, Massachusetts Institute of Technology
