Accomplish the 4Ps model using Visual Management tools: a case study approach
Full text linkThe spread of Lean methodologies in the Western production reality over the last few years, along the lines outlined by the so-called ‘Toyota Production System” (TPS) has not proven to be always effective. Implementing such a methodology is, indeed, not just a technical matter, but it also affects cultural and methodological aspects, according to the principles described by the 4P Liker’s model, namely philosophy, process, people and problem solving. A crucial factor which results to be highly important whenever undergoing an optimisation path of this kind is represented by the adoption of Visual Management, which has proven to be a back-up tool highly effective in the achievement of results in the long term. An insight regarding how these tools and techniques affect the different fields described by Liker is, though, still unknown in literature. Based on six real case studies, success stories of correct Visual Management logics implementation, this paper aims to describe the impact of Visual Management in a lean organisation, taking as reference the four distinctive dimensions described in Liker's 4P model, by building a relationship map that links visual systems with the different functionalities they absolve and the benefits they bring. The results of the analysis show how effective Lean visual systems are globally on all the considered fields, but with a different ratio among the single different tools, for which it may be necessary to take a more ‘quantitative’ approach to better define in which measure each instrument impact on the different management aspects
The communicative effectiveness of Lean mapping tools: a comparison between Value Stream Map and Makigami
No full textMapping tools have shown, over the years, their effectiveness in enabling the full potential of Lean management (LM) programs within factories. Usually deployed as “first use” practices, mapping techniques provide a wide range of benefits, starting from the identification of waste sources in value stream, up to become a blueprint for Lean implementation, as they help design how the whole door-to-door flow should operate. To this matter, two main mapping techniques can be deployed whenever it comes to a Lean optimization program: the Value Stream Map (VSM) and Makigami. Born and developed in different contexts, both of these mapping tools have shown their usefulness in providing a clear picture regarding the state-of-the-art of any given process. Still, it is not clear from scientific literature which practice best responds in terms of communicative effectiveness and which tool is most recommended depending on the context of application. Based on a real case study of a manufacturing company operating in the production of dies for aluminum profile extruders, the following paper aims to depict which tool is best suited to the proper representation of a design process in light of seven different characteristics, found in literature, used to evaluate communication effectiveness, referred as “7 Cs”. The results of the research show how effective VSM and Makigami respectively are in representing the information flow of a typical design process, but with a different ratio within the different communication dimensions

Digitally-Enhanced Shu-Ha-Ri Learning Cycle for Assembly Procedures in Smart-Lean Workstations
No full textThe critical role of sensei in developing lean leaders
Full text linkThe aim of this paper is to illustrate how lean training initiatives developed through the intervention and support of a sensei can contribute to the development of lean leadership traits in team managers. The study is carried out on a single case study conducted in an Italian SME that recently implemented lean via 10 team managers. The assessment of the leadership was carried out at different stages of the project development, through direct observation and interviews conducted by three scholars and concerned the evaluation of a set leadership skills identified in literature. The results showed that mentoring actions of the sensei increase leadership abilities of people, stimulating them to teach others only when they are promoted with the top management sponsorship and endorsement. On the other hand, the study suggests that people show different propensity to improve their leadership skills, depending on their technical background and personal experiences

Cyber-Physical Visual Management Systems in the Digital Lean Manufacturing World
No full textThe importance of Visual Management (or “Mieruka” as it is called in Japanese) has been largely demonstrated over the last few years, especially when it comes to the creation and management of data-rich environments for effective and efficient data-driven decision-making, such as digital lean smart factories. Although the different functions of visual systems are already known by the scientific community, further analysis of the capabilities and benefits provided by these tools, especially when enhanced with modern digital technologies, has yet to be provided. Therefore, this paper aims to frame a list of capabilities of the current physical visual systems, and their cyber/digital equivalents, according to a reference framework called the “7Is”, which was extracted from a review of the current literature available. This may serve as a valid common reference for future research on this topic
