Three methodologies are associated with production optimisation, namely, Theory of Constraints (TOC), Lean and Six Sigma – and each boasts with a number of success stories. This dissertation addresses the possibility of implementing all three these methodologies in a specific sequence at an organisation and also sets out to determine the impact of this implementation. A literature survey was conducted on all three stand-alone methodologies as well as on the combined methodology, which is called the Theory of Constrains Lean Six Sigma (TLS). TLS literature suggests that TOC should be implemented first with a view to identify the constraint in an organisation. Lean implementation should follow in order to eliminate any waste in the organisation. Lastly, Six Sigma should be implemented to optimise the process variability. TOC literature explains that The Goal of any organisation is to make money. All other objectives are only the means of achieving The Goal. The literature further indicates that the constraint in any organisation determines the drumbeat, and that this constraint should be managed by means of the Drum-Buffer-Rope methodology. Lean literature points towards 14 Management Principles by means of which an organisation should be managed in order to become a Lean organisation, while Six Sigma literature is concerned with the DMAIC (Define-Measure-Analyse-Improve-Control) methodology used for improvement projects and the belt system that is used to manage these improvement projects. Jonker Sailplanes, a sailplanes manufacturer in Potchefstroom, South Africa, was used as a case study for the implementation of TLS. A description is given of the processes and procedures that were followed before and after the implementation of TLS. The TLS methodology had to be adapted in order to meet the specific needs of Jonker Sailplanes into an adapted 14-step TLS implementation plan. After implementing TOC and Lean at Jonker Sailplanes, it was found that the organisation was not ready for the transition from Lean projects to Six Sigma projects. The implementation of Six Sigma was therefore referred for future research. One of the most significant findings of the current study was the very positive impact that the implementation of TLS had on the organisation: the production tempo (throughput) of the organisation has increased while the operating expenses per aircraft have decreased. This confirms that the profit per aircraft has increased. A critical evaluation of the implementation of the TLS methodology can therefore maintain that the implementation of TLS at Jonker Sailplanes was a success since the production tempo (throughput) and the organisational profit were increased and the implementation of the methodology was done with relative ease. In terms of interpreting results it was also necessary to set out how Jonker Sailplanes proceeded from a prototyping environment to a production setup, and how specifically identifying the constraint helped to achieve this transition. Furthermore, is it argued that when Lean is implemented before TOC, this could move the organisation away from The Goal, which is to make money. The interpretation of findings suggests that the procedure followed at Jonker Sailplanes was the most appropriate one. Finally, recommendations are made for future studies in terms of how to further improve the impact of the TLS implementation at Jonker Sailplanes. / Thesis (M.Ing.

Entretanto, o material referente à sua aplicação no setor de serviços, particularmente no setor de serviços financeiros, ainda é escasso. Este estudo busca ajudar a preencher esta lacuna. Neste estudo, que faz parte do campo de Operações, analisaram-se as características da implantação do Kaizen em uma instituição financeira, as práticas ou ferramentas utilizadas, as dificuldades e peculiaridades, visando entender os aspectos em que esta implantação se assemelha e também os que se diferencia em relação a um processo padrão de aplicação do Kaizen como habitualmente se encontra na indústria, área da qual se originou. Utilizou-se um grande banco privado brasileiro como estudo de caso.

Sistemas de saúde têm sido cada vez mais exigidos a serem mais eficientes, o que encorajou o uso de iniciativas de melhoria de processos. A partir de então, a Produção Enxuta (PE) surgiu como uma abordagem amplamente utilizada. Alguns resultados insatisfatórios da PE podem ser, parcialmente, explicados pela falta de considerar a complexidade dos serviços de saúde. Os sistemas de saúde são classificados como sistemas sócio-técnicos complexos (SSTC) devido à incerteza, diversidade e interações não-lineares. De acordo com a literatura, as implementações de Lean em serviços de saúde geralmente envolvem Kaizen, que tende a produzir ganhos significativos de eficiência e segurança através de mudanças relativamente pequenas e localizadas. Contudo, as melhorias locais podem implicar resultados globais indesejados, uma vez que as interações entre os elementos de sistemas complexos podem não ser lineares. Para isso, este trabalho desenvolve e aplica uma framework que visa avaliar projetos de melhoria em SSTC. O estudo foi realizado em uma unidade de internação de um hospital escola. As interações entre os projetos foram modeladas através do desenvolvimento de um diagrama de loop causal, o qual representou variáveis relacionadas a cinco projetos de melhoria analisados e um modelo FRAM. Os projetos também foram avaliados quanto ao seu impacto no sistema e sua adesão a boas práticas em Kaizen, identificadas na literatura. A framework demonstrou-se eficaz em elencar as variáveis para que possam influenciar positivamente os resultados dos projetos e embasar recomendações para a condução de novos projetos de melhoria por meio de uma visão sistêmica. / Healthcare systems have been increasingly demanded to be more efficient, which has encouraged the use of process improvement initiatives. From these, lean production has emerged as a widely used approach. Some disappointing results of lean production can be partially due to the lack of consideration of the complexity of healthcare. Health systems are classified as Complex socio-technical systems (CSTS) due to the uncertainty, diversity, and non-linear interactions. According to the literature, the implementation of Lean in healthcare usually involves Kaizen, which tends to produce significant gains in efficiency and safety through relatively small and localized changes. However, local improvements may imply unwanted overall results, since interactions between elements of complex systems may not be linear. For this, this work develops and applies a framework that aims to evaluate improvement projects in CSTC. The study was performed in an in-patient surgical ward of a teaching hospital. The interactions between the projects were modelled through the development of a causal-loop diagram, which accounted for variables related to all five projects, and a FRAM model. The projects were also evaluated as to their impact on the system and their adherence to good Kaizen practices identified in the literature. The framework proved to be effective in highlighting the variables so that they can positively influence the projects results and support recommendations for conducting new improvement projects through a systemic view.

Annotation: Lean Management as an Ethical Problem Business management methods are mainly depended on what the company is doing. One of the management options is lean management which is typical for the automotive industry, but is used for its efficiency in other industries as well. It is a method of management that maximizes labor productivity, reduces the financial burden in the production process, and reduces human errors. The main goal of this thesis is focused on explaining the basic concepts of economics and ethics focused on the way of business management. It includes a description of a specific case of the implementation of lean management in a particular company. An ethical reflection follows, which focuses on comparing the described implementation with the presented company values. Second point is the reflection of lean management with the theory Stakeholder. The work concludes with a description of the consequences of the implementation of systems focused primarily on efficiency and profit with possible solution points. Key words: lean management, ethical management of a company, manager, employee, corporate culture, efficiency, profit, key indicators, corporate values, code of ethics, stress.
