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.

Gestão de portfólio de produtos em pequenas empresas de base tecnológica

The product portfólio management is considered relevant activity to the proper performance of the product development process. This paper aims to present the main methods of management that technology-based small businesses adopt for decision-making in product portfolio. This survey, which collected data on 31 companies was conducted. It was observed that although firms adopt market research and mapping methods and financial methods and for this decision-making, most of them based on the informal deliberations of senior management. Unable to understand the business relationships between the presence of ISO 9001 certification with greater formalization for decision making in product portfolio.

Estudo da viabilidade de produção da peça alimentação/ladrão para banheiras

The product development field daily works in the chase of new materials and technologies that fulfills the requirements of the consumer market. So, projects are developed in order to theoretically predict what will actually happen. The production of household appliance is not different. To provide a pleasant bath to the costumer, the manufacture of a bathtub counts on many components. With this in mind, this work goal is to study the possibility of production by plastic injection of the assembly water source/overflow pipe used in bathtubs and compare its production cost with the cost of the assembly acquired from third parties. The injection process is widely used on the world stage because of its numerous advantages, however, due to the high cost of the molds, it is important to estimate the time required for the return of the initial investment. To do this, a model was designed to examine its dimensions and then initiate the study of the possibility to inject the components with the available injection machine and the production cycle. With the results, it was found that there was a reduction in the cost of the finished assembly, but a very long time to return the initial investment due to the current financial scenery of the country

Simulação da suspensão tipo duplo A de um veículo off-road através do histórico de excitação do solo

The search for mechanical components validation methods, employed in product development sector, becomes more avid for less expensive solutions. As a result, programs that can simulate forces acting on a given part through finite element method are gaining more space in the market, once this process consumes less capital when compared to currently-employed empirical validation. This article shows the simulation of an off-road prototype suspension through such technique, using ground excitation history coming from field measurements and also by making use of a specific tool for obtaining dynamic loads from the model in question. The results shown at the end is key for future enhancements aiming mass reduction, for example, that may be executed on the prototype suspension system discussed here

Análise do processo de preparação da produção no desenvolvimento de novos produtos por meio de um estudo de caso em uma empresa do setor siderúrgico

A demanda por novos produtos tem aumentado em algumas empresas do setor siderúrgico, indicando uma crescente preocupação com o desempenho do processo de desenvolvimento de produtos (PDP), que depende de vários elementos conceituais importantes apontados na literatura. Em uma empresa siderúrgica, um fator relevante é o projeto do processo de produção, devido à característica de ser um processo de fabricação contínuo e por, geralmente, envolver investimentos significativos na fase de preparação da produção. Nesse contexto, o presente trabalho busca realizar uma análise desta fase em uma empresa siderúrgica. Pretende-se, por meio da abordagem metodológica de estudo de caso, identificar práticas organizacionais, focando nos aspectos operacionais e suas interfaces, envolvendo as áreas funcionais de marketing, engenharia do produto e manufatura. Também é tratada no trabalho a integração dos times multidisciplinares, a tomada de decisão e os critérios para avaliação dos resultados do PDP. O trabalho conclui que a empresa analisada utiliza-se de práticas que estruturam a preparação da produção e que a integração interfuncional das áreas é o que se destaca para o sucesso do PDP.

Uma investigação sobre a relação entre o projeto do produto e produção em uma montadora automotiva e fornecedores de motores que adotam a modularidade

A modularidade pode ser entendida como um conjunto de conceitos que leva a novas possibilidades de arquitetura de produto, bem como novas maneiras de organização da produção, possibilitando a transferência de atividades ao longo da cadeia de suprimentos automotiva. Nesse contexto, o objetivo deste trabalho é investigar o emprego da modularidade no projeto de produto e na produção, considerando uma situação de relação específica entre uma montadora de veículos comerciais e fornecedores de motores, no âmbito do consórcio modular. É também analisada a relação entre a modularidade no projeto de produto e na produção. Para a consecução desses objetivos é adotada a abordagem metodológica de estudo de caso. Os resultados apresentam algumas influências que ocorrem entre o projeto do produto e a produção e vice-versa, uma parte delas esperadas, reforçando o caráter confirmatório dos dados coletados. Constata-se que o conceito de modularidade pode ser aplicado ao processo produtivo sem necessariamente que o produto tenha sido concebido em módulos, ou seja, a partir de um produto existente é possível montar seus componentes formando subconjuntos em uma lógica modular. Os dados confirmam ainda que a estrutura do produto de um veículo comercial favorece a sua divisão em módulos. Adicionalmente, a gestão da cadeia de suprimentos na montadora é simplificada em comparação ao sistema de produção convencional, pois parte das responsabilidades da montadora é transferida para os fornecedores.

An initial proposal for PDP of smes developing hospital furniture

A large percentage of the industrial SMEs has an organizational structure for product development too far from the adequate practices and models, elaborated by renowned authors with expertise in the theme of product development. On the other hand, the authors state that SMEs obtain considerable advantages by adopting a model of product development process (PDP) management. Healt is one of the most innovative sectors in the world, and countries like Brazil and Colombia are transitioning from a system that cares for contagious infecttions diseases where the drug product is the main form of treatment - to a system that cares for chronic degenerative conditions - where the equipment, including hospital furniture, has more relevance to the treatment. This change is offering better opportunities of specialized markets to hospital furniture SMEs that adopt an adquate PDF model. The present study proposes a first outline of a model of PDP management for industrial metal-mechanical SMEs that develop and manufacture hospital furniture, from a review of models proposed for great mechanical area.

Strumenti e metodi per lo sviluppo prodotto di lenti oftalmiche

The recent introduction of free form NC machining in the ophthalmic field involved a full review of the former product development process both from the design and the manufacturing viewpoint. Aim of the present work is to investigate and to set up innovative methods and tools supporting the product development, particularly for lenses characterized by free form geometry, as e.g. progressive lenses. In the design stage, the research addressed geometric modeling of complex lens shapes and relevant analysis tools for the optical-geometrical characterization of the produced models. In the manufacturing stage, the main interest was focused on the set-up of the fabrication process, particularly on the NC machining process for which an integration CADCAM software was developed for the generation and the simulation of the machining cycle. The methodologies and tools made available by the present work are currently used in the development of new complex geometry product typologies as, e.g. progressive lenses.

Deposition, imaging, and clearance: what remains to be done?

Deposition and clearance studies are used during product development and in fundamental research. These studies mostly involve radionuclide imaging, but pharmacokinetic methods are also used to assess the amount of drug absorbed through the lungs, which is closely related to lung deposition. Radionuclide imaging may be two-dimensional (gamma scintigraphy or planar imaging), or three-dimensional (single photon emission computed tomography and positron emission tomography). In October 2009, a group of scientists met at the "Thousand Years of Pharmaceutical Aerosols" conference in Reykjavik, Iceland, to discuss future research in key areas of pulmonary drug delivery. This article reports the session on "Deposition, imaging and clearance." The objective was partly to review our current understanding, but more importantly to assess "what remains to be done?" A need to standardize methodology and provide a regulatory framework by which data from radionuclide imaging methods could be compared between centers and used in the drug approval process was recognized. There is also a requirement for novel radiolabeling methods that are more representative of production processes for dry powder inhalers and pressurized metered dose inhalers. A need was identified for studies to aid our understanding of the relationship between clinical effects and regional deposition patterns of inhaled drugs. A robust methodology to assess clearance from small conducting airways should be developed, as a potential biomarker for therapies in cystic fibrosis and other diseases. The mechanisms by which inhaled nanoparticles are removed from the lungs, and the factors on which their removal depends, require further investigation. Last, and by no means least, we need a better understanding of patient-related factors, including how to reduce the variability in pulmonary drug delivery, in order to improve the precision of deposition and clearance measurements.
