Ítem How to Foresee and Measure the Real Economic Impact of a Lean Manufacturing Implementation(Springer Heidelberg, 2013-06-25) Manotas, Diego F.The academic and industrial worlds seem to agree in the convenience of implementing Lean Manufacturing. Arguments to highlight the benefits of implementing Lean usually include testimonials from successful companies, published case studies, even conference presentations, plant tours, and television programs. It is not easy to foresee the impact of a Lean implementation in strictly monetary terms. Lean is an operational philosophy that does more than saving money; it prepares companies for sustained improvement and creates disciplines and operational capabilities, yet it could be argued that these capabilities are hard to value and quantify. In this paper, we propose a flowchart-type methodology to decide if a change in a procedure, in the use of tangible resources or in the use of time brought about by the implementation of a Lean Manufacturing technique will have a measurable economic impact. The decision maker will need to know the specific circumstances of the production system, but we believe he will be able to predict the economic impact of a Lean implementation (or to evaluate the results of an ongoing Lean project) with more precision, to build a stronger and more comprehensible business case and convince upper management of the real benefits of Lean.Ítem Aplicación de herramientas de pensamiento sistémico para el aprendizaje de Lean Manufacturing(Universidad Icesi, 2010-03-24T23:30:08Z) Rivera Cadavid, Leonardo; Dinas, Johan Armando; Franco Caicedo, PaulaLean Manufacturing seeks to eradicate waste. This pursuit is conducted changing many pre-conceptions inherited from the mass production traditions. It is necessary to understand immediate and delayed impacts of the changes, as well as direct and indirect results of these changes. This systemic approach should enhance the learner’s understanding of the system (the manufacturing company), its variables, its outcomes, and the relationships among the system’s components. This paper presents the process of designing a course to teach Lean Manufacturing to working professionals using systems thinking. This design process is conducted for the development of job competencies and using Active Learning Strategies.Ítem Lean Manufacturing measurement : The relationships between Lean activities and Lean metrics(Universidad Icesi, 2007-10-01) Manotas Duque, Diego Fernando; Rivera Cadavid, LeonardoLean Manufacturing was developed by Toyota Motor company to address their specific needs in a restricted market in times of economic trouble. These concepts have been studied and proven to be transferrable and applicable to a wide variety of industries. This paper aims to integrate a set of metrics that have been proposed by different authors in such a way that they are consistent with the different stages and elements of Lean Manufacturing implementations. To achieve this, two frameworks for Lean implementations are presented and then the main factors for success are used as the basis to propose metrics that measure the advance in these factors. A tabular display of the impact of “Lean activities” on the metrics is presented, proposing that many a priori assumptions about the benefits on many different levels of improvement should be accurate. Finally, some ideas for future research and extension of the applications proposed on this paper are presented as closing points.
