 Herbie
Avez-vous lu « The Goal? » Vous rappelez-vous Herbie ? Le modèle de la Théorie des Contraintes ou Theory of Constraints (TOC) de Eliyahu Goldratt est le résultat pratique de son travail au sujet de « comment penser ». Dans un certain nombre de livres, Goldratt a décrit certains processus de pensée et leurs applications.
Lien de cause à effet dans la Théorie des contraintes
Le concept central de la TOC est la reconnaissance du lien de cause à effet. Comparez : Diagramme de Causes et Effets. Les Processus de pensée de la TOC nous donnent une série de phases qui combinent les causes à effets et notre expérience et intuition pour acquérir des connaissances. La TOC est une philosophie vérifiable. En sachant comment nous devrions penser, nous pouvons mieux comprendre le monde autour de nous ; par une meilleure compréhension nous pouvons nous améliorer.
Les organisations sont un toile (web) complexe de personnes, équipements, méthodes, matériaux et mesures. Cette complexité de détail est assez mauvaise. joutez-y la complexité dynamique de changement des clients, des fournisseurs, du personnel, des réglementations, etc. et vous avez une image de l'enjeu à relever par une équipe de management d'aujourd'hui.
Traditionnellement, la gestion a divisé l'organisation en plus petites, plus maniables parties. L'objectif est de maximiser la performance de chaque partie. L'amélioration globale est supposée être égale à la somme des améliorations locales.
Faux ! La TOC prétend qu'un changement de la plupart des variables dans une entreprise aura seulement un petit impact sur la performance globale - sur le résultat. Il y a très peu de variables, peut-être seulement une, où une amélioration significative de performance locale cause une amélioration significative dans la performance globale. Une telle variable s'appelle « Constrainte ». Vous pouvez la comparer avec le lien le plus faible d'une chaîne. Comparez : Diagramme de Gantt.
Les phases de la Théorie des contraintes. approche
L'essence de l'approche de la TOC est que si vous voulez réaliser plus que votre but, vous devez :
- Identifiez votre Contrainte.
- Concentrez-vous sur la Contrainte. Une entreprise doit d'abord connaître son but et les conditions nécessaires pour la réalisation. Alors elle doit identifier la (les) Contrainte (s), celle (s) qui limitent le niveau de la réalisation de ce but.
- Suivez-la à travers. Un processus d'amélioration continue :
1. Identifiez la Contrainte.
2. Exploitez-la.
3. Subordonnez toutes les autres opérations à la nécessité d'exploiter la Contrainte.
4. Si après #2 et #3 plus de capacité est nécessaire pour satisfaire la demande du marché, augmentez la Contrainte.
5. Retournez à #1, mais ne laissez pas l'inertie devenir la Contrainte du système.
