Importance of decision-making in a purchasing context – DPS Case Study

This work project has the objective of exploring the importance of making good decisions on supplier selection, so that the purchasing department can contribute to the success of a company. For that it is presented a short bibliography review of the latest insights that were found relevant, on the subjects of purchasing, technology, outsourcing, supplier selection and decision-making techniques. For a better understating on how to deal with a decision-making situation, a case study is also presented: Digital Printing Solutions (DPS) is a Portuguese company that provides complete and integrated printing solutions and has been planning to contract a software supplier. DPS has no formal supplier-selection model and it has to choose between 2 suppliers. The case study was solved using the M-MACBETH software. I have found that complex decisions-making situations can be easily overcome by using the M-MACBETH decision model. Moreover, the usage of a model, instead of decision that follows no formal procedure, provides the decision maker with insights that can be useful to negotiate with the supplier.

Modelo de estrutura organizacional baseado nos princípios do pensamento Lean

No caminho da competitividade, a gestão das Organizações tornou-se cada vez mais complexa. Como observaremos ao longo do trabalho, a complexidade resulta da realidade interna das Organizações mas, acima de tudo, do ambiente organizacional que condiciona fortemente a realidade interna. Para responder às diferentes solicitações, requisitos e pressões concorrenciais a integração tem-se mostrado uma vantagem competitiva para as Organizações que nesta ferramenta têm apostado, obtendo melhores resultados de produtividade e de motivação dos recursos humanos. Paralelamente à continua integração de diferentes aspectos, as Organizações têm procurado concentrar-se no seu core business e passar para outsourcing as actividades de apoio à sua missão, visando “emagrecer” a Organização mas mantendo ou melhorando os rácios de eficácia e eficiência. Para tanto, há que actuar sobre a Estrutura Organizacional concebendo uma gestão integrada de todas as actividades de suporte, visando libertar recursos para o cumprimento da missão da Organização. O presente trabalho visa apresentar uma Estrutura Organizacional que, assentando na Logística Estratégica e considerando os princípios do Pensamento Magro, permitirá a integração dos processos de suporte e a clarificação dos processos da missão, logo da competitividade da Organização. A análise detalhada das diferentes estruturas organizacionais conhecidas e normalmente implementadas nas Organizações, permitiu perceber que estas estruturas precisam de evoluir por forma a permitirem uma melhor resposta aos ambientes organizacionais mais turbulentos e complexos. Como resultante conceptual do presente trabalho alcançámos a Estrutura Organizacional Lean (EOL) com vantagens potenciais significativas nomeadamente ao nível da redução dos desperdícios organizacionais e da agilidade organizacional, sendo possível esperar um melhor desempenho organizacional. Para o desenvolvimento do trabalho recorremos à Soft Systems Methodology (SSM), aplicando, de forma simulada, o modelo numa empresa referência no mercado e avaliando o desempenho estimado com a aplicação do modelo à realidade organizacional em questão. Os resultados obtidos podem ser considerados muito interessantes segundo as vertentes da Eficácia, Eficiência, Efectividade, Ética e Elegância (5E’s).

Development of paper transistor with memory effect

This work will discuss the use of different paper membranes as both the substrate and dielectric for field-effect memory transistors. Three different nanofibrillated cellulose membranes (NFC) were used as the dielectric layer of the memory transistors (NFC), one with no additives, one with an added polymer PAE and one with added HCl. Gallium indium zinc oxide (GIZO) was used as the device’s semiconductor and gallium aluminium zinc oxide (GAZO) was used as the gate electrode. Fourier transform infrared spectroscopy (FTIR) was used to access the water content of the paper membranes before and after vacuum. It was found that the devices recovered their water too quickly for a difference to be noticeable in FTIR. The transistor’s electrical performance tests yielded a maximum ION/IOFF ratio of around 3,52x105 and a maximum subthreshold swing of 0,804 V/decade. The retention time of the dielectric charge that grants the transistor its memory capabilities was accessed by the measurement of the drain current periodically during 144 days. During this period the mean drain current did not lower, leaving the retention time of the device indeterminate. These results were compared with similar devices revealing these devices to be at the top tier of the state-of-the-art.

A proactive approach o XY international expansion

This work project was conducted under a Direct Research internship (DRI) that consists on an individual dissertation established on a given organization. DRI has a problem solving format to an empirical question to be addressed, «Which country has the highest potential for the next step of XY internationalization process? ». In order to achieve the project’s purpose, it was conducted a scanning process using a top-down approach over an initial list of nine countries given by XY. To do so it was developed an international scanning framework based on different domains and weights that allowed to achieve the top two countries with highest potential. After an in depth analysis over the final set, it was recommended Switzerland as the best country to make the next step of XY internationalization in Europe.
