Industrial Context

AbstractRequirements engineering and requirements management are essential sub-processes of product development and are an integrated part of virtually all product development models and industrial process descriptions. Proprietary and context specific processes for working with requirements are used in industrial design practice. However, these are not appropriately reflected in existing process models for product development. Existing standards describe the content and generation of requirements documents but not their integration in the product development process.The study is based on a retrospective analysis of a set of representative real-world product development projects from automotive industry and rail industry. Comparing the processes downstream the milestone “release of PRD”, it was found that subsequent processes to manage requirements and specifications do not differ much with regard to industrial context. Based on this, a model for the product requirements specification (PRS) process is proposed which addresses the gap.

Abstract Based on an analysis of the product development process and the study of relevant product development models, the paper presents a new approach aiming at modeling and supporting the design activity as the substantial activity within the product development process. The Autogenetic Design Theory is an approach advancing general design theories. It facilitates the integration of intuition, creativity and artificial intelligence into the conventional design process. To this end, a phase-like allocation of the design process is assumed as the essential structure and an evolutionary algorithm is integrated as the core facilitating purposeful searching and combining. Hence, the flow of the design process can be influenced as all requirements can be included and, on the other hand, intuition and creativity are ensured through the evolutionary algorithm.

Structure Knowledge

The product development capability is a core competence in a company, and the product development process is a knowledge-intensive process. The evolution of engineering design shows that knowledge is a key factor of a successful product development. From the 70's in the last century, artificial intelligence has been introduced into this field. It evolves from expert system through knowledge-based system to current knowledge management. Knowledge taxonomy is a core component in knowledge management. A new approach of mapping knowledge in product development through process modelling is proposed. Product development process modelling can help people structure knowledge and the employees linking to each activity in the product development process. According to the analysis of product development process models, there exist three basic kinds of objects: product states, process elements, and resources. The state-process-resource model provides available ontologies of knowledge in the product development domain. In this way, knowledge is hierarchically classified into six knowledge subjects: product, product process, process element, method, tool, and application specific domain. Furthermore, each of the knowledge subjects is divided into three types of knowledge: course, practice, and expertise location.

AbstractThe amount of new virtual reality input and output devices being developed is enormous. Those peripherals offer novel opportunities and possibilities in the industrial context, especially in the product development process. Nevertheless, virtual reality has to face several problems, counteracting reliable use of the technology, especially in ergonomic and aesthetic assessments. In particular, the discrepancies in perception between the real world and virtual reality are of great importance.Therefore, we discuss these most important issues of current virtual reality technology and highlight approaches to solve them. First, we illustrate the use cases of VR in the product development process. In addition, we show which hardware is currently available for professional use and which issues exist with regard to visual perception and interaction. Derived from the depiction of a perfect virtual reality, we define the requirements to address visual perception and interaction. Subsequently we discuss approaches to solve the issues regarding visual perception and evaluate their suitability to enhance the use of virtual reality technology in engineering design.

AbstractPrototypes are often used as a tool in the product development process and their usage is advised in many guidelines, frameworks and product development methods. Those prototypes achieve different goals of which most relate to getting new insights and information about the product in development. For the development of those prototypes however, significantly less development methods are available compared to the number of methods for the development of products. Investigating the process of using a prototype leads to the idea that the main purpose of those prototypes is describable as learning about the product. This idea is elaborated further and followed by the introduction of the detailed process model for prototyping which is primarily based on the detailed process model for products. However, the purpose of the prototype differs from the purpose of the product which leads to some significant changes of the model. To give an example of a prototyping process, the development of a sensor- integrating elastic claw coupling is introduced and analysed. In addition, this paper discusses the question, how other product development models may be applied to the development of prototypes.

Generic Process

A very large majority of the current product development process models put forward in textbooks present a homogenous structure, what Ulrich & Eppinger [1] call the market-pull model, presented as a generic one, while other possible product development process models are merely seen as variants. This paper focuses on the task clarification and derived activities (mainly the systematic search for customer needs through market study and the supplementary development costs it entails) and investigates two alternative strategies that are not derived from the generic process model. The first alternative is the market-pull model without an extensive task clarification. The second is the application of the so-called expeditionary marketing strategy. With the help of simplified analytic modeling, the conditions for which these alternatives are as efficient as the generic process model are discussed. This advocates the development of more flexible process models.

Cultural aspects and Maslow needs has been considered on product development process. There is also has indication of product selection mutation based on Maslow needs ability. Based on these conditions, formulation of successful product development strategy in the future need to consider cultural aspects. Therefore, the purpose of this study is to determine mathematical model of products four-wheeled vehicles and to predict success. Stages of research include developing mathematical models, the validation process models and best model selection. The results of a mathematical model based on market share indicates that the component must-be inversely proportional to the success of the product, while the components of one-dimentional and attractive is directly proportional to the success of the product. The calculation result that Kano generate mathematical equations require further research. These research expected can determine the success of the model with the parameters of the success product in addition to market share.

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.
