The researchers developed a systematic process of four steps for the implementation of the first two steps of TOC-DBR in Make-to-Order production systems. This process was derived from the seminal work from Goldratt, introduced key insights from Resource Based View (RBV) and Practice Based View (PBV) strategic perspectives and included original contributions from the authors in understanding what purpose should be fulfilled, what decisions should be made and how the four steps should be applied.Design/methodology/approach: Given the practical nature of the research project, action research (AR) is an appropriate methodological approach, since AR aims to contribute to academic research while helping solve real-world problems.Findings: The proposed systematic process has been successfully tested in the field on a Make To Order case company. ...

Even if problems related to this kind of environment are the most common, the analysis of the literature shows that, as it has happened to Critical Chain, it has been paid little attention from academia, focusing mainly on other areas, such as algorithms for planning and scheduling. Given the purpose of the thesis, it was decided to run case studies using action research as the core of a three-phase research project. In the first stage a contrast between the literature review and the perspective of the entrepreneurial world has been carried out by an interview. The second phase has developed an innovative learning method designed to perform in labour contexts. Finally, the third stage comprehends four case studies developed in companies with different characteristics and scenarios. The implementation ...

So, in 2002 the Project Based Learning (PBL) was started-up in engineering courses for the first time. This methodology is used in multidisciplinary units that have been designed for each one of the semesters of every degree. Both the design and the tracking of the projects, which are done by the students, are the responsibility of the team of teachers responsible for that semester. The application of this method is based on the identification of those subjects that are complementary to each other, so that is built a structure of subjects that make possible to the student the development of his/her technical capabilities. These capabilities can be directly related to the functions that the students will have to fulfil at work, methodological capabilities which will train them in project management or transversal competences, focused in training the student for living in professional environments. ...

Además, se ha visto la necesidad de proveer conocimiento personalizado los empleados, sin que por ello tengan que ausentarse demasiado del puesto de trabajo para asistir a cursos tradicionales (y así perjudicar la correcta ejecución de sus proyectos dentro de la empresa). Así, se ha identificado un vacío que consiste en la falta de integración del conocimiento directamente (y de forma rápida) en las tareas cotidianas del trabajo. El presente documento recoge los contenidos básicos de una metodología de formación que trata de combinar las potencialidades de dichos métodos y el apoyo de la universidad por medio de la figura del “facilitador” para su aplicación al entorno laboral. El método ha sido desarrollado en el seno del proyecto CEE as WBL, y se ha aplicado en varias empresas. A la espera de los resultados definitivos, ya se perfilan algu...

[1] aims to analyze the impact of protective capacity on the application of the third step of the drum-buffer-rope methodology of the theory of constraints (subordinate everything to the bottleneck) in make-to-order environments. To analyze the impact of protective capacity, a discrete event simulation is performed. Experimental results suggest that, at different levels of variability, different levels of protective capacity are needed to keep the system stable. The higher the variability, the higher the level of protection needed. It can be concluded that the definition of the level of protective capacity required is a strategic decision for the organization. For managers to know and control how much protection is necessary and how much is overcapacity or waste, monitoring and managing the use of protective capacity is paramount. This concept of protection monitoring and control is relatively new in the theory of constraints methodology, b...

The results suggest that at different levels of variability, different levels of protective capacity are needed to keep a system stable and meet the bottleneck (BN) schedule. The higher the variability is, the higher the level of protection needed. The definition of the level of protective capacity required is a strategic decision for the organisation, as it must be emphasised that with high levels of variability in a system, the protective capacity must be very high, which contradicts the efficient use of resources. However, for managers to know and control how much protection is needed without needing additional capacity, it is advisable to monitor the use of protective capacity. This concept of protection monitoring and control is relatively new in the TOC–drum-buffer-rope (TOC-DBR) methodol...

However, some difficulties have been detected in implementing this methodology in such changing environments. This case study analyses a MTO company to identify the key factors that influence the execution of the third step of TOC. It also aims to evaluate in more depth the research started by Lizarralde et al. (2020) and compare the results with the existing literature.Design/methodology/approach: The case study approach is selected as a research methodology because of the need to investigate a current phenomenon in a real environment.Findings: In the case study analysed, the protective capacity of non-bottleneck resources is found to the key factor when subordinating the MTO system to a bottleneck (BN). Furthermore, it coincides with one of the two key factors defined by the literature, namely protecti...

Thus, the relationship between S & OP can be critical from a competitive point of view, and therefore strategic. However, most of the literature on this topic focuses on the field of repetitive manufacturing. Consequently, this work aims to enhance the scarce literature related to S & OP in organisations that produce make-to-order (MTO). The present study is an analysis of cases of two industrial companies managed according to the theory of constraints. In both cases, the relationship between sales and operations was initially poor. Their approaches were mainly founded on their experience and intuition, as well as on simple data. The development of a new approach, integrating S & OP, has demonstrated the potential advantages of integrated management. As a result, we have identified some aspects of interest from a managerial perspective. Fur...

El estudio se centra principalmente en los aspectos relacionados con el aprendizaje de la utilizacion en la practica de los metodos agiles Scrum y Kanban. Su uso como base para la gestion de los proyectos en un entorno cuasi-real ha permitido identificar aspectos de interes. El primero se refiere a la perspectiva del formador, y el segundo al aprendizaje de personas, muchas de las cuales contaban con escasa o nula experiencia profesional.

En este se describen los aspectos fundamentales de la implantacion de la filosofia TOC y sus implicaciones para la organizacion. En un contexto como es el de la caldereria de precision no tiene sentido gestionar los recursos con la perspectiva tradicional de produccion de series largas. En el contexto actual, donde lo habitual es tener muchos pedidos de pocas unidades (proyectos concretos), el objetivo debe ser alinear el uso de los recursos (capacidad) hacia la velocidad de facturacion (entrega en plazo), dandole prioridad al flujo como clave para el aumento de la productividad global, y no la busqueda de optimos locales como medio para buscar el objetivo final. Por ello el proyecto se ha centrado en el alineamiento del sistema hacia objetivos globales, haciendo hincapie en los siguientes aspectos: • Enfoque basado en la teoria de las limi...

Years ago, the traditional project management faced problems when operating in these environments. Thus, at the end of the 20th century, new project management approaches were conceived to provide a more effective answer to such contexts. These methods propose a different approach, aimed at promoting the project flow by focusing on the short term. However, their adoption involves certain adjustments from a managerial perspective. The influence on the way resources are used is of special interest, as it may cause unexpected behaviors and reactions. The literature vastly analyzes the features and benefits of these methods. Nevertheless, there is a lack of empirical evidence about both the practical implications of the transition process toward them and their superior performance. Thus, this research aims to contribute to filling this gap by providing real-world based evidence related to the ch...

En la revisión de la literatura se han identificado trabajos de investigación que analizan el funcionamiento de esta metodología en entornos simulados. Sin embargo, no se han encontrado estudios que analicen la implementación del DDMRP en una empresa real. El presente trabajo, por lo tanto, analiza la evolución que una empresa que fabrica componentes para electrodomésticos obtuvo al migrar del MRP al DDMRP. Los resultados obtenidos, demuestran que gestionando los materiales con la metodología DDMRP la empresa aumentó la visibilidad en la cadena de suministro reduciendo considerablemente el efecto bullwhip y los pedidos urgentes. Cabe destacar también la evolución del inventario, ya que el stock físico se redujo mientras que el consumo de los materiales aumentó. Du...

La secuencia en la que se lanzan los trabajos al sistema está determinada por la programación del Drum. En la literatura se observa que está demostrada la validez del método para gestionar la producción, pero la mayoría se centran en estudios analíticos y no tienen en cuenta casos reales de producciones bajo pedido y plantas v. En este estudio exponemos un proceso sistemático para la implementación de los dos primeros pasos de TOC en sistemas productivos. Lo hacemos desde una perspectiva estratégica, esto es, el recurso que controla el lanzamiento y ritmos de producción debe ser una decisión gerencial.
