Creating outstanding products is vital for a company's endurance in competitive markets. A mix of functionality, ergonomics, aesthetics, symbols and price aspects all play a role in making a product desirable. This exploratory study concentrates on communicative and meaningful aspects in a product's design. It examines how the creation of a communicative design occurs during the product development process. Multiple product development projects in two distinct companies were analysed. In two projects, specific attention was given to communicative aspects in the product's design. These two projects are examined in this paper.

Engineering design is naturally dominated by technological knowledge, but there is a need now for greater consideration to be taken of the needs of individual humans and of society in general. Many of the criticisms of engineering designs (civil, mechanical, electrical and chemical) made during the last twenty years, could have been avoided if more consideration had been taken of the human factors. In the processing and manufacturing industries concerned with marketing consumer products, there has developed a process for design which combines the technological design with consumer needs - this is called product development. Product development is the process used from the development of the initial idea for a new product to the final launching of the product on the market. At all stages of product development, the consumer is involved in the design of the product from the initial creation of the product idea to the testing of the final product. The human needs from a product and the methods used to incorporate them in the design are discussed. It is suggested that these methods can be used to incorporate the human factor into any engineering design, and that the product development process can be applied in other areas of engineering as well as the consumer product industries.

This study aims to probe into the influence of new product design and new product development process management on development performance. The research finding demonstrates that product design reveals positive and significant influence on new product development performance. Through statistical analysis, this study finds that companies in Taiwan value new product design. When companies value it more, they tend to have better new product development performance. With regard to the relation between new product development process management and new product development performance, the empirical results demonstrate that companies would pay more attention on new product development process management. With regard to new product idea and assessment, concept design and development, product function test and mass production in the market, through statistical analysis, this study finds that companies that value process management of new product development tend to have better new product development performance. As to the influence of new product design and new product process management on new product development performance, statistical analysis result demonstrates that the integration between new product design valued by companies in Taiwan and development process management would lead to significantly positive influence on new product development performance of the companies.

Abstract By many measures, U.S. industry is no longer the leader in developing world class products. U.S. product development and manufacturing systems need substantial improvement to assure a successful future. The Superior Engineering Design Program (SEDP) was created within the University of Tennessee’s College of Engineering in 1987, with a mission to improve the teaching and practice of product development. Within this program, the authors have developed a computer-based learning tool, the “SEDP Product Development Guide” (“the Guide”), to help senior and graduate engineering design students learn “superior” product development processes. The Guide incorporates the latest product development strategies and techniques, as practiced by some of industry’s most competitive product development teams. The software is an assistant, but is specifically not an “artificial intelligence” system that purports to make decisions for the user. Rather, the guide provides structure and asks “critical” questions at appropriate times during the product development process. While design tools are available for assistance, the student engineer is always responsible for answering the “critical questions” satisfactorily to assure that the designed product meets customer requirements. A prototype SEDP Product Development Guide has been installed for evaluation in the SEDP’s Engineering Design Center, located in the University’s Mechanical and Aerospace Engineering Department.

Introduction 1.1 What is collaborative product design and developmentCollaborative product design and development (CPD) is also known as collaborative product definition management (cPDM).It is about business strategy, workflow and collection of software applications that facilitates different vendors to work together on development/design of a product.The early participation of vendors in the design process is considered critical in order to improve the product quality and reduce the development cycle time.CPD is becoming more valuable because of the increasing coordination and management complexity of organizational information, responsibilities, schedules, deliverables, product information, and business process.As outsourcing and globalization increase the number of design chain participants, a CPD speeds up the decision-making of trusted partners, employees, suppliers, and customers in design chains.Design chain is a subset of supply chain.The major collaborative activities between suppliers and manufacturers are design activities.Therefore, how to manage the design flow in a design chain is as important as how to manage the material flow in a supply chain. What are the main phases of product design and developmentBefore discuss the collaboration issues for product design and development, we need to briefly review the phases of product design and development.The major phases of product design and development are normally defined as conceptual design, preliminary design, and detail design and development (Blanchard, 2004).During the conceptual design phase, the concepts, which are also called scheme, are built in order to completely and efficiently design the transceiver.The concepts may include such as product operational requirements and maintenance, current product problem (or deficiency), functional analysis for the product, applicable technical performance measures (TPMs), and specific performance measures and design-to criteria.Preliminary design phase begins with a "functional baseline" product configuration described in the product specification prepared during conceptual design phase.The functional baseline is translated into detailed qualitative and quantitative design requirements for allocating applicable elements of the product.An "allocated baseline" configuration in the form of development, product, and process specifications is established during this phase.At the beginning of detail design and

Although the systematic use of design methods is critical for improving product development, its acceptance by industries has been lower than expected. The purpose of this study is to establish the frame conditions for implementing design methods for product development in the consumer goods industry. The research strategy consists of analysing the implementation of design methods in five large Brazilian product development companies in different segments. The implementation of the design methods was through workshops with departments related to product development activities, and the evaluation was based on the observations of the process, responses to questionnaires and interviews with the participating employees. The key findings of this study are 11 factors that influence an industry's adoption of product development design methods. These findings include not only methods-related suggestions, such as guidelines for the selection and the form of application of the design methods, but also suggestions for actions that should be taken at the cultural and structural levels of the companies. The main contribution of this study to design research is that it elicits discussion about the product development aspects that are often the main factors of failure and/or divergence in an implementation.

Users consume products all the time, while companies produce products all the time. Product is the fundamental where enterprises have their foothold and product development is the only way to business survival and development. To conduct effective product development, enterprises must have scientific marketing strategy and rational ideas of development. Therefore, to analyze the ideas in product development design from the perspective of product extension in marketing helps expand the vision in product development, define product development objectives and also helps to find the accurate positioning of product design.

This paper analyzes design equilibrium in a concurrent product-development project using the results from behavioral game theory. In this study, a project consists of a team of three engineers who represent three product-development stages: product design, material selection, and process selection. Product-development tasks are globally distributed, and engineers are allowed to independently make product-development decisions (i.e., non-cooperative design). In addition, the engineers are evaluated according to the outcomes of both individual and team product-development tasks. When multiple design equilibria exist, but a dominant design equilibrium does not, the past behavioral-game-theory studies indicate that design equilibrium may be reached under two conditions. In the first condition, one engineer is allowed to announce his/her intended alternative even though he/she does not need to actually choose the announced alternative. In the second condition, one engineer is selected to make his/her choice first but the other engineers do not know what that choice is. Sensitivity analysis indicates that a wide variety of design equilibria will emerge depending on how engineers are evaluated.

Coordination within the team is a cornerstone of effective teamworking. This paper argues that Concurrent Design is a means to achieve effective product design and development. Concurrent Design is a proposed system for the organisation and management of multidisciplinary project teams and activities for the purpose of concurrent product development. Concurrent Design comprises mechanisms which support the product design process by bringing together appropriate resources and by co-ordinating and controlling the whole development process to ensure that the product reaches the market in a timely manner, without incurring unnecessary cost. This paper considers new methodologies towards the development of a management support environment for new product development and proposes a framework for the structuring and modelling of the teamworking environment. It has been developed from research that has included an investigation of methodologies for concurrent product development, organisational design, and a survey of problems and priorities of new product development in the UK textile and apparel industries. The paper analyses design activities from different design aspects within a teamworking organisation, and describes the structure of teamworking co-ordination in a product design setting. Finally, a model for Concurrent Design is proposed for effective product design and development.

Taiwanese electronics and computer products are well respected by consumers globally. This study examines local electronics and computer enterprises to identify the product development strategies applied to deal with global competition and attain competitive advantage. Based on questionnaire results, product development strategic groups were categorised for the Taiwanese electronics and computer industry in response to global competition. In total, 48 products developed by these strategic groups were analysed in terms of the relationship between product development strategies and product design issues. The results demonstrated that enterprises in different strategic groups for product development responded to different design issues. Notably, correlations existed between enterprises in different strategic groups and their product designs. Different mapping patterns were identified in new product types, design features, market goals, and design appeals for enterprises in different product development strategic groups. These mapping patterns could serve as references for product innovation and new product development.
