Nível de maturidade e comparação dos PDPs de produtos automotivos

O desenvolvimento de novos produtos, que atendam às necessidades do mercado consumidor, é atividade estratégica para sustentabilidade das organizações. O objetivo deste artigo é comparar e avaliar o nível de maturidade desses processos em duas montadoras de veículos instaladas na região Sul Fluminense do País. São discutidas algumas características dos processos, expõe-se o modelo de avaliação, baseado nos critérios do CMMI (Capability Maturity Model Integration), e são apresentados os resultados de pesquisa que investigou o nível de maturidade junto a 47 representantes das empresas estudadas. Como resultado, foi possível identificar lacunas na estruturação dos PDP's, com diversas práticas e ferramentas usadas de forma isolada e não integradas, havendo campo suficiente - no entendimento dos próprios executivos - para serem aprimorados e refinados, o que permitiria torná-los mais completos, abrangentes e potentes para alavancar os resultados de mercado e financeiros das próprias organizações.

Product development process: Using real options for assessments and to support the decision-making at decision gates

Enterprises need continuous product development activities to remain competitive in the marketplace. Their product development process (PDP) must manage stakeholders' needs - technical, financial, legal, and environmental aspects, customer requirements, Corporate strategy, etc. -, being a multidisciplinary and strategic issue. An approach to use real option to support the decision-making process at PDP phases in taken. The real option valuation method is often presented as an alternative to the conventional net present value (NPV) approach. It is based on the same principals of financial options: the right to buy or sell financial values (mostly stocks) at a predetermined price, with no obligation to do so. In PDP, a multi-period approach that takes into account the flexibility of, for instance, being able to postpone prototyping and design decisions, waiting for more information about technologies, customer acceptance, funding, etc. In the present article, the state of the art of real options theory is prospected and a model to use the real options in PDP is proposed, so that financial aspects can be properly considered at each project phase of the product development. Conclusion is that such model can provide more robustness to the decisions processes within PDP.

Integration practices for the technological innovation of products: Case studies at two large technological companies

Studies on innovation and technology management have emphasized the importance of integration between the research and development (R&D) department and others involved with the product development process (PDP) as a relevant practice for the good performance of technological innovation of product activities. This study addresses the topic of transfers of technologies to new product projects and also integration practices between the R&D department and others involved with the PDP. A qualitative study was conducted that was operationalized through two case studies at large high-tech companies: One is Brazilian and the other is a multinational subsidiary in Brazil. Among its main result, this paper represents and analyzes management practices that are favorable to integration in product development projects that demand development and transfer of technologies, such as: participation of R&D personnel in market activities, the adoption of virtual interaction mechanisms, and the application of methods such as technology roadmaps. © Universidad Alberto Hurtado, Facultad de Economía y Negocios.

Avaliação teórico-experimental da distribuição de dose absorvida em radioterapia em tumores de pele

O trabalho propõe rotinas computacionais usando o Método de Monte Carlo com o Código MCNP-5, para analisar os perfis de dose de radiação liberada nos tratamentos de tumores de pele e otimizar os cálculos radiométricos dos feixes de radiação estudados. Foram realizadas medidas dosimétricas do feixe de radiação, comparando os resultados obtidos com os respectivos valores fornecidos pelo serviço de física médica das instituições, com resultados informados pelo fabricante do equipamento e com as simulações computacionais efetuadas com o Código MCNP-5. A quantificação dos erros relativos percentual entre os resultados simulados e os fornecidos pelo Serviço de Radioterapia (E1), os informados pelo fabricante (E2) e os medidos experimentalmente (E3) são inferiores a 4,0% e validam a metodologia computacional proposta para avaliação do comportamento do feixe de raios-X superficial e do feixe de raios γ da unidade de Cobaltoterapia. A metodologia de análise do espectro energético e da curva de porcentagem de dose profunda (PDP) desenvolvida neste trabalho pode ser estendida para estudos de outros feixes clínicos e subsidiar os dados radiométricos utilizados nos planejamentos e cálculos de dose realizados pelo profissional da física médica na sua rotina nos Serviços de Radioterapia

Radioterapia em câncer de mama: importância da determinação da curva de isodose

The study analyzed contours of the thoracic region of patients undergoing radiotherapy of breast tumors in Hospital Manuel de Abreu of Bauru (institution 1) and the Hospital da Faculdade de Medicina of Botucatu (Institution 2). Were prepared isodose curves corresponding to the contours of the patient, which were presented for radiotherapists doctors both hospital services that enabled the choice of the curve isodose that provides the best distribution of radiation dose in the irradiated volume. Some boundaries were digitized in one institution and sent for preparation of isodose lines in the institution 2, both curves plotted in each of the institutions and for the same contour, were compared, showing that the methodology of Curves of distance is feasible and reliable, while optimizing the routine procedures regarding the handling of isodose plans provided by different radiation equipment. It compares the calculation of the exposure time determined using the isodose curve selected by calculating the value obtained considering the PDP at the point of the middle line of separation between the internal and external fields, the difference between the two methods for determining exposure time was around 2.4%. A study on the angle of the radiation beam at the input field (region breast-air) was conducted showing that, once known a tangent angle of the input beam, one can estimate the angle of the wedge filter used in some procedures for uniformity of dose within the irradiated volume compensation and the lack of tissue in the treatment volume. A comparative study between the isodose curves produced manually with the curves obtained in a two-dimensional computer system, the computer system showed that provides further information regarding the dose gradient within the irradiated volume, in addition to reducing the time spent in preparing the curves isodose

Diagnóstico do nível de maturidade do processo de desenvolvimento de produtos: um estudo de caso em empresa calçadista

The process of product development (PPD) is a strategic factor in which companies seek to identify consumer needs. The relationship of the practices adopted, tools, techniques, among others, can determinate the maturity level of the company in this process. The purpose of this paper is to understand and diagnose the level of maturity of the PDP in footwear segment industry. For the case study, a company inserted into one of the largest poles of women’s footwear in Brazil, located in Jaú, São Paulo State, was researched. The diagnosis is based on the maturity levels of the unified model, reference in the process of product development, proposed by Rozenfeld et al. (2006). The application of the model assisted to diagnose the current maturity level of the company in this process, providing useful information to achieve higher levels of maturity in the PDP.

Evaluation of maturity levels in the management of product development: case studies in the capital goods industry

In recent approaches to the management of product development process (PDP), maturity levels have attracted the attention of practitioners and researchers. The CMMI model contributes to evaluate the maturity levels and improvement of the product development process management. This paper, based on CMMI model, analyzes the practices adopted in two companies of the capital goods industry, which develop and manufacture equipment upon request. It was observed that on account of market conditioning factors and different practices adapted to PDP management, these companies are at different maturity levels. One company is at the initial level of maturity while the other at the most advanced one. It was also noted that the application of CMMI model can provide improvement to PDP management, as well as present guidelines to achieve higher maturity levels, adequate to companies' needs.

Gestão de portfólio de produtos: práticas adotadas por uma empresa de base tecnológica de médio porte localizada na cidade de São Carlos, SP

In the context of the product development process (PDP), portfolio management plays an important role by determing the set of products that a company uses to compete. Due to its characteristics, performing continuous technological forecasting activities for developing and transferring technologies to their products through the PDP, this tends to make portfolio management a complex activity for products at these companies. This paper’s objective was to identify practices for product portfolio management in a medium-sized technology-based firm located in São Carlos, SP. Qualitative research was used and it was operationalized through a case study. Among the main results, it was noted that decisions on product portfolio depend mainly on the perception of senior management and the financial analyzes constitute the main method used for supporting the decision.
