DESARROLLO DE UNA METODOLOGÍA DE IMPLEMENTACIÓN DE LOS CONCEPTOS DE TOC (TEORÍA DE RESTRICCIONES), PARA EMPRESAS COLOMBIANAS José Arturo Gonzáles Gómez Katherine Ortegón Mosquera Leonardo Rivera Cadavid Administración y Contabilidad TOC PyMEs calidad estrategia diagnóstico La Teoría de Restricciones (TOC) esun sistema de pensamiento gerencialque ha sido aplicado con éxito enmultitud de empresas en el mundo.Sin embargo, no existe una documentaciónadecuada de su implementaciónen Pequeñas y Medianas Empresas(PyMEs) en Colombia, por lo queno hay un protocolo de implementaciónque guíe al empresario en dichoproceso.Al realizar una investigación documental,unida con un diagnóstico yaplicación piloto en dos pequeñasempresas del sector de manufacturade productos plásticos, se estructuróuna propuesta que parte desde conocerel estado actual de la empresa,satisfacer algunos requerimientos previos a la implementación de técnicasde TOC y la implementaciónpropiamente dicha de las mismas.Como conclusión se encontró queantes de emprender cualquier procesode mejoramiento es necesario ordenarla casa: Lograr una claridaden los aspectos administrativos, productivosy de calidad básicos, para asígarantizar la efectividad y sostenibilidadde cualquier avance que se alcance. 2003 artículo científico 0123-5923 https://www.redalyc.org/articulo.oa?id=21208702 es http://www.redalyc.org/revista.oa?id=212 Estudios Gerenciales application/pdf Universidad ICESI Estudios Gerenciales (Colombia) Num.87
