O setor automotivo se caracteriza pela busca por redução de custos e de desperdícios em seus processos produtivos. Desta forma, torna-se necessário o uso de melhores práticas para se manter competitivo no mercado. Dentre estas práticas, destaca-se a metodologia Lean Manufacturing (LM), proveniente do Sistema Toyota de Produção, a qual propõe melhorias nos processos, por meio da eliminação das perdas. Mesmo que estudos estejam em andamento e que, eventualmente, suas ferramentas sejam empregadas de forma isolada no meio empresarial, não há um consenso a respeito do tema e das principais métricas utilizadas para verificar seus benefícios quando da implantação e uso integral das práticas enxutas. Sob este aspecto, a dissertação buscou compreender, por meio de um estudo de caso múltiplo exploratório com abordagem qualitativa, como os fatores contextuais influenciaram o uso de práticas Lean e suas métricas de avaliação em cinco empresas do setor automotivo da Serra Gaúcha. Com base na bibliografia sobre o tema e nos instrumentos de pesquisa aplicados, obteve-se, como resultado central, a compreensão sobre quais são os fatores contextuais que influenciaram ou ainda influenciam o uso de práticas enxutas, além do levantamento de quais eram as principais métricas utilizadas nestas empresas para fortalecer e aprimorar seu sistema produtivo. / The automotive sector is characterized by the search for cost reduction and waste in their production processes. Thus, it becomes necessary to use best practices to stay competitive in the market. Among these practices, there is the Lean Manufacturing (LM), from the Toyota Production System, which proposes process improvements through the elimination of waste. Even if studies are in progress and that eventually, their tools are employed in isolation in business world, there is no consensus on the subject and the main metrics used to verify its benefits when deploying and full use of lean practices. In this regard, this dissertation aimed at understanding, through an exploratory multiple case study with a qualitative approach, how the contextual factors influencing the use of Lean practices and its evaluation metrics in five companies belonging to the automotive sector in south region of Brazil. Based on the literature about the subject and applied research tools, was obtained as a central result, the understandings of which were the contextual factors that influenced or influence the use of Lean practices, besides a survey of the key metrics used in these companies to strengthen and enhance its production system.

M. Ing. / According to Taque (2005: 30), current lean manufacturing can be presented as ineffective due to a lack of guidelines for establishing and implementing the application thereof. In this project, guidelines for the implementation of lean manufacturing were developed using data collected from multiple sources. One of these sources were company visitations conducted at Desta Power Matla (DPM) in Johannesburg and Bosch SA in Brits. In addition, interviews were conducted with an expert in the field of lean manufacturing, ECSA-accredited professionals in the field, academics in industrial engineering and workers who use lean manufacturing. The significance of this study lies in assisting employees in understanding lean manufacturing production and then developing and implementing guidelines for its implementation. The study also brings to the fore the role of the individual worker in acquiring knowledge about and an understanding of lean manufacturing guidelines. This will ultimately enable companies to implement lean manufacturing production successfully. The results emerging from the data were used to develop guidelines for lean manufacturing production.

This article examines the problem of an increase in product returns for a company that produces plastic films for flexible packaging. Among the factors that have resulted in the increase of returned products are defects in the films caused by the poor manipulation of materials and, above all, the hard point in the coils caused by excessive extruder preparation time, causing the extrusion head to overheat as well as uneven extrusion. Extrusion is a key process in the production of plastic materials as it transforms polypropylene and additives into plastic sheets. The delay in the preparation time caused by machine operators leads to the overheating of the extrusion head and, therefore, defective products that are ultimately returned to the company by customers. In order to confront this problem, a proposal was developed using the SMED tool of Lean Manufacturing in order to reduce the preparation time of the extruder and to increase the productivity of the company. For the validation of the proposal, we simulated the system to determine the resulting reduction in extruder preparation time.

M.Tech. (Operations Management) / The research is about the application of lean manufacturing tool known as manufacturing kaizen in order to improve a work process at . The company is based in Kempton Park, South Africa, used as a case study to evaluate the benefit of manufacturing kaizen at a specific industrial concern. The research demonstrated how manufacturing kaizen when used appropriately can help APSAP PTY LTD to eliminate waste, have better inventory control, short process cycle times, and better overall financial and operational procedures. The goal was to reduce the identified waste using manufacturing kaizen tool. Waste reduction eventually reduced the cycle time of the work process. The primary objective of the thesis was to study and analyze the cylinder preparation process in APSAP PTY LTD. The process activities were captured, then analyzed using the process map. The secondary objective was to identify waste in the process. Major businesses in South Africa have been trying to adopt new business initiatives in order to stay competitive. One way to increase this is to apply proper manufacturing strategy and use of lean manufacturing or continuous improvement tools to achieve business objective which is to stay competitive and to increase profit. The research addresses the application of a lean manufacturing tool called manufacturing kaizen. Manufacturing kaizen refers to a technique used for improving a work process by the eliminating waste within that process in the organization. It is one of the improvement tools that focus on cost reduction by eliminating non-value added activities. Kaizen achieves the elimination of waste by empowering people with tools and a process to uncover improvement opportunities and make change. Participants are key aspect in implementing the manufacturing kaizen event, since they are the people directly involved. Identifying the key people that will be used in the manufacturing kaizen event is very crucial for the success of the event. Any changes or improvements of the process will have direct impact to the people. It is important that people who are directly affected by change become part of the process and feel empowered. Kaizen understands waste to be any activity that is not value adding from the perspective of the customer. The research unpacks manufacturing Kaizen and looks into its qualitative nature and its application within a working environment and how it influence productivity. It also investigates how this tool can be applied in a process or chemical industry and the benefits it can provide to an organization. The initial step in the approach was to outline data collected and examining techniques used to collect the data. The researcher carried out direct observation as he was physically present, and personally monitored what was taking place. The results show that labor productivity can be improved over time after the introduction of manufacturing kaizen. It concludes that with the introduction of manufacturing kaizen, transformation at workplace can be established leading to productivity improvement within an organization. The research has shown that with the proper use of manufacturing kaizen , waste reduction can be achieved.

Governments around the world want to deliver better education, better health care, better pensions and better transportation services. They know that impatient electorates want to see change, and fast. But, the funds required to meet such expectations are enormous, particularly in the many developed economies where populations are aging and the public sector's productivity has not kept pace with that of the private sector. The need to get value for money from governments at all levels is therefore under the spotlight as never before. However, cost-cutting programmes that seek savings of 1 to 3% per year will not be sufficient and, in some cases, may even weaken the quality of service (Bhatia & Drew, 2006). One of the key innovative means to improve productivity, and do more with less, is through the implementation of lean initiatives. The purpose of this study is to conduct an 'Assessment of the status of lean implementation at selected SARS (South African Revenue Service) branch offices'. Literature review was conducted to investigate the origins of lean and how the service industry tapped from this philosophy, which was initially developed for the manufacturing sector. The lean philosophy has now been widely adopted in various service industries, from government agencies such as the South African Revenue Service to financial institutions such as ABSA bank, including the healthcare industry. The findings of the research indicated that even though the organisation has made a strategic decision to implement lean, this has not been entirely successful as there is a lack of understanding of lean among managers and team leaders. There are some pockets of excellence though. The researcher recommends that a comprehensive road map be developed to guide the organisation into a sustainable lean implementation.

Central to the sustainable and competitive growth of the South African construction industry is a predictable cash flow through on time payment by clients to contractors. However, chronic late payments, a recurring problem in the industry, especially in the public sector, is bringing untold hardship to contractors by derailing their competitiveness and also eroding the trust among the supply chain partners to the extent that some firms end up closing business in the industry. The situation is viewed from the lean construction perspective as an obstacle that is preventing the accrual of the required value to project parties in the construction industry. This research addresses the causes of late payments to contractors and the role of the quantity surveyor (QS) in terms of influencing early payment from a lean construction perspective. A mixed method approach was used for compiling the primary data for the study. Sequentially, one hundred and two (102) quantitative and twelve (12) interview questionnaires were administered to selected contractors and construction professionals working predominantly on public sector projects. The findings revealed that the approval process for evaluation and certification by the client- appointed agent and intermediary institutions is taking longer than contractually allowed, with parties independently undertaking their evaluation prior to the certification date. This is found to be adverse to achieving consensus on the values of the works for authorisation. Other significant barriers are the lack of funds to authorise payment, random auditor general’s documentation changes, lack of administrators’ system integration and capacity to handle cyclical payment processing. Also, contractors have been found to be in default of timeously submitting complete claim documents. It is therefore recommended that the client agents should partner with the contractor in regular design and documentation reviews, arranging the payment process and should also meet jointly to prepare monthly evaluations. In addition, contractors should be mentored from the onset of the project regarding all the necessary documentation and supporting documents that will be required by the client to ensure that payment approvals are not delayed. The payment authori-sation agent’s capacity should be enhanced through training and improved powers as a singular point of control to perform efficiently and their systems and processes should be integrated to ensure that all parties are implementing the same protocols.

This research report examines the changing nature of the organisation of work, in particular, the production methods in the South African automotive industry. The competition in the local and global markets has increased significantly in recent years. The increased complexity of products and individuality of customers pose strong challenges for the automotive manufacturers, (OEM – Original Equipment Manufacturers), with regard to product Quality, Cost and Delivery. For these challenges, Volkswagen Group South Africa, has defined objectives that, when met, will contribute towards establishing it as a leading automotive brand. It is aligned to the Volkswagen Group AG, Strategy Mach18, increased vehicle production and the creation of long-term delighted customer base. To achieve these objectives, the Volkswagen Production System (VPS) is an imperative component of the Volkswagen Group South Africa (VWGSA) production strategy. The core elements consist of, “Cycle”, “Flow”, “Pull” and “Perfection”. These are the four fundamentals on which Lean Manufacturing is built, as first introduced and described by the Toyota Production System. Lean manufacturing is a whole-systems approach that creates a culture in which everyone in the organisation continuously improves the process and production. Volkswagen Group South Africa is facing increased competition in the South African and global marketplace. A search of the internet revealed that extensive research has been conducted into Lean manufacturing in South Africa. However, no research is noted with regard to the sustainability of Lean manufacturing at Volkswagen Group South Africa. The aim of this study is to analyse the sustainability of the lean manufacturing implementation at VWGSA.
