An assessment has been done and waiting times between production processes have been identified, along with defective products and inefficient work methods. This study proposes the design of a lean manufacturing model under the change management approach, whose methodology comprises five phases. In phase 0, awareness and training sessions are conducted (change management). Then, phase 1 reorganizes the work area (plant layout re-distribution and 5S) and phase 2 seeks better workload balances (line balance and Heijunka implementation). Later, phase 3 standardizes work methods (standardization). Finally, the proposed model will be validated to determine whether the selected operating tools are supported by the awareness that contributes to increasing production. © 2021, Springer Nature Switzerland AG. / Revisión por pares

Production Control Model Using Lean Manufacturing Tools and Kanban/CONWIP Systems to Improve Productivity in the Process of Sand Casting in a Heavy Metalworking SME

Prada-Echevarría, Luz, Chinchay-Grados, Jorge, Maradiegue-Tuesta, Fernando, Raymundo, Carlos 01 January 2021 (has links)
El texto completo de este trabajo no está disponible en el Repositorio Académico UPC por restricciones de la casa editorial donde ha sido publicado. / The contribution of the metalworking sector to the gross domestic product is decreased by 8.6% in the 2017–2018 period because of problems such as high rejection rates, lead times, and raw material losses. Consequently, the sector’s production was reduced by PEN 1,200,000 while demand remained flat. Thus, this article proposes a production control model using 5S, Single-Minute Exchange of Dies, and tools such as Kanban and Constant Work-in-Progress (CONWIP) to increase the productivity of a sand casting line in a Peruvian metalworking enterprise that manufactures parts for mining on request. The improvement proposal involves the implementation of lean manufacturing tools and analyzes low productivity effects. The problems identified are typical of the Peruvian metalworking sector; thus, this study may contribute to finding possible solutions for issues faced by other enterprises. / Revisión por pares

Investigating Safe Implementation In Railway Industry : A case study at Alstom DC Sweden

Ahmad, Bilal, Kosasih, ii Ratna January 2021 (has links)
Organizations have always tried and pushed themselves to bring changes in how they conduct business. They do this to reach the market quickly and achieve customer satisfaction. This master thesis was conducted at a global leader transportation company, Alstom, to investigate Scaled Agile Frameworks (SAFe) adoption in their Sweden Development Centre, identifying SAFe implementation challenges in a safety-related development as a single-case study. For the thesis, two research questions were formulated to identify the implementation challenges and find their reasons. For the data collection of the thesis, semi-structured interviews, self-completion surveys, and relevant research papers were used to serve the purpose of both primary data and secondary data sources. The researchers acted as ethnographers by participating in the company’s daily events and taking notes. The analysis of the collected data was done using the triangulation approach to get reliable results. In addition, researchers also used SAFe core competency assessment to evaluate the business agility of the case organization.The analysis from the collected data resulted in five implementation challenges. The data suggested that the major challenge was insufficient training and lack of agile mindset among the team members. The case organization had invested in training and support for going through the transformation, but the agile training was interrupted in 2019. Since then, the knowledge about SAFe and the agile way of working was acquired based on learning by doing. Based on the data, the researchers concluded that lack of continuous training has resulted in the development over time of other implementation challenges like insufficient self-organization, nonoptimal team size, and lack of clarity when defining role responsibilities. The data also suggested that transparent communication between different levels may still be a challenge. The SAFe assessment that has been conducted resulted in confirm previous result that in some places complemented the identified implementation challenges.  Key Words: Scaling Agile Framework, Implementation challenges, Lean, Waterfall, Self-organization, Continuous learning culture, Safety related development, Business agility, Ethnography.

Combining Frugal Innovation, Inclusive Business, and Scrum for Addressing Low-income Contexts with Sustainability Considerations

Lange, Anne 21 October 2021 (has links)
Sustainability and the penetration of new markets beyond developed industries are two topics that are gaining increasing attention both in research and in business practice. As Western industries are becoming saturated, companies are looking for further business alternatives and are focusing on North-South opportunities, among others. Therefore, bottom-of-the-pyramid markets are often mentioned as promising mass markets. However, market access remains a challenge, as bottom-of-the-pyramid contexts are characterized by low incomes, resource constraints, and infrastructural barriers. In addition, sustainable practices are a challenge. Since the introduction of the Sustainable Development Goals by the United Nations, which apply to all countries, companies are required to address aspects of sustainability in their business practices. However, they have to cope with conflicting dimensions inherent to sustainability such as improving economic and social aspects, which are usually accompanied by higher resource demands and environmental degradation. Previous literature started to address these issues by focusing on innovative approaches such as frugal innovation, social innovation, or resource-constrained innovation. In the last decade, research on frugal innovations has particularly focused on how to address the challenges of low-income and resource-constrained contexts, often with aspects of sustainability in mind. However, to address these low-income contexts, having a suitable innovation is not enough; businesses must actually reach the target group, such as by overcoming accessibility issues in rural areas. Initial research has examined the value chains of frugal innovations and ways to engage the consumer, which also leads to social improvements. Building on this research, this dissertation combines four themes – frugal innovation, sustainability, inclusive business, and Scrum – to illustrate how innovations can address the needs of target groups in bottom-of-the-pyramid contexts and how these innovations can be implemented by engaging target customers. The first paper illustrates the links between frugal innovation and sustainability based on a new sustainability evaluation framework. All cases considered contribute to sustainability, with social improvements being most notable. New employment and income opportunities are key social improvements. They reflect inclusive business approaches, which are the focus of the second paper. The case examples of the second paper show how frugal innovation can be implemented in accordance with inclusive business, which leads to customer involvement and thus mutually supports frugal innovation. The Inclusive Business Link Model for Frugal Innovation was built to show connections of frugal innovation and inclusive business and to provide application possibilities. A key finding was that for the cases considered a high level of customer integration can be achieved through frugal innovations with modular designs and is supported by knowledge transfer and partnerships. To address knowledge transfer and partnerships in particular, the last paper applies Scrum as an agile approach at the execution level for inclusive business. In developing the conceptual model Inclusive Business Scrum Approach, inclusive business is considered as the 'what' and Scrum as the 'how' in engaging low-income consumers. With regard to all three papers and the four included topics, this dissertation achieves several outcomes and contributes to a broader view of how low-income consumers can be addressed. First, each paper illustrates benefits of combining the concepts that could be valuable when addressing the bottom-of-the-pyramid context. Thereby, the papers build on each other and include previous results. Second, aspects of social sustainability are addressed mainly by combining frugal innovation and inclusive business. Third, each paper develops a model or framework intending to support practical applicability. Finally, an outline is provided for how combining frugal innovation, inclusive business, and Scrum positively could impact partnerships, knowledge transfer, and the empowerment of the target group, which could culminate in an approach that addresses challenges experienced when entering the Bottom of the Pyramid that also considers sustainability. The new management options developed begin at a general level and end at an execution level and thus contribute to holistic perspectives on innovations, approaches, and implementation options for organizations intending to address the Bottom of the Pyramid.:Abstract 1 Table of Contents 3 List of Abbreviations 6 List of Tables 7 List of Figures 8 1 Introduction 9 2 Theoretical background 15 2.1 Defining sustainability 15 2.2 The BoP as target group 18 2.3 Frugal innovation 20 2.4 Inclusive business 22 2.5 The agile approach Scrum 25 2.6 Contribution of the investigations and the current relevance of topics 28 3 Methodology 30 4 Papers 32 4.1 Publication 1: Introducing a Sustainability Evaluation Framework based on the Sustainable Development Goals applied to Four Cases of South African Frugal Innovation 32 4.1.1 Introduction 33 4.1.2 Theoretical background and research context 34 4.1.3 Methodology 38 4.1.4 Developing an evaluation framework 40 4.1.5 Limitations 44 4.1.6 Introducing the frugal cases 44 4.1.7 Findings 45 4.1.8 Discussion 48 4.1.9 Conclusion 49 4.2 Publication 2: How Frugal Innovation and Inclusive Business Are Linked to Tackle Low-income Markets 51 4.2.1 Introduction 51 4.2.2 Literature review 55 4.2.3 Methods 62 4.2.4 Results 66 4.2.5 Cross case analysis 75 4.2.6 Inclusive business integration stair model 77 4.2.7 Development of propositions 82 4.2.8 Discussion 84 4.2.9 Research implications 86 4.2.10 Managerial implications 87 4.2.11 Concluding remarks and future research 88 4.3 Publication 3: Boosting Inclusive Businesses’ Opportunities Through the Adoption of Scrum: an Execution Strategy to Enter Low-end Markets 91 4.3.1 Introduction 92 4.3.2 Theoretical background 94 4.3.3 Conceptual model: Inclusive Business Scrum Approach 99 4.3.4 Challenges 106 4.3.5 Summary of key facts and propositions 108 4.3.6 Conclusion 111 4.3.7 Research implications 112 4.3.8 Managerial implications 113 4.3.9 Limitations and future research ideas 114 5 Discussion 116 5.1 Social sustainability 117 5.2 Partnerships 118 5.3 Knowledge transfer 118 5.4 Empowering the target group 119 5.5 Context challenges 119 6 Critical considerations and additional thoughts 121 6.1 Definition and contributions of frugal innovation 121 6.2 Sustainability of initiatives at the BoP and inclusive business 122 6.3 Aspects of leadership theories in Scrum 124 7 Methodological limitations 126 8 Research implications and future research ideas 128 9 Managerial implications 131 10 Conclusion 133 11 References 135 11.1 List of interviews 171 11.2 Further references used in Publication 2, anonymized form 171

Propuesta de mejora en la cadena de suministro de la producción de palta hass utilizando SC. Agility en Carac, Huaral / Proposal for improvement in the Supply Chain of Hass Avocado production using SC. Agility in Carac, Huaral

Paredes Robalino, Sebastian Omar, Guzmán Marcó, Angelo Fernando 04 August 2021 (has links)
Este trabajo de investigación está enfocado en la cadena de valor de la venta internacional de palta Hass de la producción obtenida de la ciudad de Carac, Huaral con la finalidad que los agricultores de esta zona pueden obtener mayores ingresos económicos. Dentro de la zona se realizó un censo y se obtuvo como resultado que 12 de los 13 agricultores realizan venta de su producto directamente a un bróker. Además, se tuvo como resultado todo el flujo de la venta, desde la compra de materias primas hasta el envío de la palta de forma internacional. Debido al resultado, se pudo identificar los procesos que realizan los agricultores y cuáles son los que realiza el bróker. Con el fin de que el bróker no realice todas las funciones del flujo, se planteó que los agricultores tengan mayores procesos a su cargo, como son el de transporte y de la exportación, de esta manera el bróker se convertiría en un “agente de ventas”. Se realizó una prueba piloto en un contenedor LCL y su rentabilidad fue de 100 dólares En conclusión, los procesos se dividirán en 3 etapas: Compras, Transporte y Exportación. El bróker se encargará de conseguir las ventas internacionales y el ahora comprará las paltas a los agricultores a un costo mayor, teniendo como resultado un incremento de S/1.05 por Kg por parte de los agricultores. / This research work is focused on the value chain of the international sale of Hass avocado from the production obtained from the city of Carac, Huaral with the purpose that the farmers of this area can obtain greater economic income. Within the area, a census was carried out and it was obtained as a result that 12 of the 13 farmers sell their product directly to a broker. In addition, the entire flow of the sale was obtained, from the purchase of raw materials to the shipment of the avocado internationally. Due to the result, it was possible to identify the processes that farmers carry out and which ones are carried out by the broker. In order for the broker not to perform all the functions of the flow, it was proposed that farmers have greater processes in charge, such as transport and export, in this way the broker would become a "sales agent”. A pilot test was carried out in an LCL container, and its profitability was 100 dollars In conclusion, the processes will be divided into 3 stages: Purchasing, Transportation and Export. The broker will be in charge of achieving international sales and he will now buy the avocados from the farmers at a higher cost, resulting in an increase of S / 1.05 per Kg by the farmers. / Trabajo de Suficiencia Profesional
