Abstract In socialistic countries, customer satisfaction and the market conditions were not of high priority: Some selected parts of the market products were of satisfactory costs and quality to customers. Quality and costs of a product decide on its success in the world-wide market. The wishes and expectations of the customer for a high-quality and low-priced product continue to grow, however, with the desire for faster availability of this product. The customer determines also the delivery time and other competitive factors as the durability of the product. At present the trend goes towards shorter product life cycles, which in turn requires reduced time spent on the product development. With these complex market requirements and growing diversity of the products the engineer faces new challenges in his development tasks. It can be paraphrased as follows: In reduced lifecycles a quality-assured and advantageous product has to be developed despite increasing complexity of the design and demands for reduction of material used, manpower and monetary spending. For the solution of this complex problem the following suggestions are tested and implemented: • Structured design process for the development process, • Simultaneous work where ever possible during the development stages, • Employment of modern resources for the product development, • Use of information technology and • Implementation of rapid prototyping for models and in secondary manufacturing processes. An important research field at the Department of Mechanical Engineering Design at the Otto-von-Guericke-University Magdeburg is research and further development of productive procedures and tools for the realization of a computer integrated product development process. This process includes the effective application of technologies to produce the prototypes for presentation, producibility analysis and production. Of particular interest is the closed process chain (loop) from Solid Modeling via Rapid Prototyping and 3D-Digitizing where the entry point of this process chain depends on the needs of the application or particular interest of the innovating company. Information for faster and more competitive preparation, verification and Re-Engineering of existing and established products, which have to be adjusted to the world-market needs, will be made available. The results of this applied research offer opportunities to display new developed products for the lagging industries in the former East Germany, and furthermore arranging for necessary venture capital to produce the product, to gain information about possible suppliers and manufacturing opportunities in order to minimize the investors’ risks of an enterprise.

Many manufacturers believe building of physical prototypes is a bottleneck that slows down production process and increase production cost. However, since the quest for reality ends up with making real objects, physical prototypes cannot be out-rightly eliminated in product development process. With the advent of rapid prototyping technology (3D printer), manufacturing is now possible at any scale, from units of one to millions, large or small batches. Thus, rapid prototyping is seen as a possible technology for enhancing product development process; especially in small and medium industries that relies on manual production techniques. Hence, this paper investigates the viability of rapid prototyping technology in small and medium industries. With particular reference to ceramic industry, the paper demonstrates how the contemporary technology (Rapid prototyping) can be harmoniously merged with conventional techniques, so as to enhance product quality and reduce development time and cost.

This paper examines modern methods and approaches to product development in the context of the volatility of the world market. To achieve maximum customer focus and successful delivery of their products, services and services, more and more companies are focusing on flexible approaches to product development. The changing business environment and the emergence of new mechanisms of interaction with customers lead to the need to create approaches such as "Lean Startup". Its core principle is a validation process in each product development process, which will increase the ability to create a better product and reduce the time spent on the path from development to market.

User-centered product design (UCPD) and especially its methods and tools offer a lot of benefits to product development. By using specific data of the user group or by including them into the design process, systems with better functionality and usability arise. However, including the users in an optimum manner means to include them over the whole product development process, which is costly and often too time-consuming regarding the ever shorter product life cycles. An extensive application of UCPD methods is therefore usually not practical for industry. In order to (1) support the user-centered development process in general and (2) support the selection of appropriate UCPD methods, a multi-channel human-system interaction framework is proposed. It is derived from existing human-computer and human-machine interaction models and further includes additional factors influencing the human-system interaction. However, the framework itself needs further and more detailed elaboration and discussion and currently lacks an allocation of UCPD methods.

Abstract Rapid prototyping has become a key factor in reducing the cost and time to market associated with new product development. Unfortunately a lot of the potential time and cost savings associated with rapid prototyping are lost due to the use of processes that are incompatible with the type of information needed by the designer at any given point in the product development process. A quantitative measure is proposed in this paper for the value of a prototype at any given point in the product development process, where value is defined as a function of benefit (information learned) of a prototype and the cost of the prototype. The value measure is utilized to suggest prototyping technologies to aid the designer in selecting appropriate technologies. Three different value metrics were developed: one based on the benefit-to-cost ratio, one on utility theory, and one on value theory. The value metrics are applied to an industrial example, a cash register till, and compared on their ability to suggest appropriate prototyping technologies along the design time-line.

An accurate understanding of users' needs is essential for the development of innovative products. This article presents an exploratory method of user centered research in the context of the design process of technological products, conceived from the demands of a large information technology company. The method is oriented - but not restricted - to the initial stages of the product development process, and uses low-resolution prototypes and simulations of interactions, allowing users to imagine themselves in a future context through fictitious environments and scenarios in the ambit of ideation. The method is effective in identifying the requirements of the experience related to the product’s usage and allows rapid iteration on existing assumptions and greater exploration of design concepts that emerge throughout the investigation.
