The product development process is a series of asynchronous process steps in which the geometry, the materials, and the manufacturing processes are defined to meet the performance and cost requirements. During the product design, information about a product is initially sparse and becomes more detailed as the process matures. In this paper, we apply a systems complexity analysis methodology to track the evolution of information complexity for several design process workflows. We used a frame-slot based model to store parametric design information, defined the size and link complexity measures for the design information and tracked the evolution of the knowledge-base complexity throughout the design process. Product design through injection molding is taken as an example to illustrate the utility of our approach and the static and dynamic aspects of the complexity of design information are analyzed.

Abstract One cannot design in a vacuum; the goodness of a product is almost always (except in the case of a novel design) measured with respect to an existing design. It is logical, therefore, to have a design process that takes competitors into account. Competitor’s hardware is a rich source of design information providing concept and design solutions, current market trends, cost and quality drivers, missing functionality and unwanted functionality. This paper presents a methodology to systematically evaluate existing designs using a process called benchmarking. In addition, a methodology for incorporating the benchmark information into the specification, concept, embodiment, detail design phases of the product development process is described.

A major challenge in industry today is to reduce the cost and cycle time in product development while maintaining enough flexibility to adapt to changing markets. Businesses are requiring more and more flexibility in order to produce custom goods at low cost. A new strategy called the Product Design Generator is presented to provide flexible product platforms through an automated design process where product variation is built into the product development process and is achieved through scalable and in some instances modular parametric models for a given product platform embodiment. A case study of web-based Product Design Generator is presented. The axial turbine disk Product Design Generator demonstrated cycle time reduction from 500 man hours to 15 minutes. This new product development strategy has demonstrated the potential to provide engineers the ability to study more potential design solutions, reduce the number of opportunities to introduce error in the product development process, and allows companies to apply a consistent design process across the organization.

Current trends in product development process highlight the increasing adoption of digital data and virtual processes. Nowadays, a huge amount of product data are collected without a clear management strategy and, oftentimes, they dont even cover the whole product development process. A global and integrated planning about information needed to sustain product design process is not a trivial task and, usually, companies underrates this issue. From the perspective of virtualization of processes, and then their automation, the lack of structured knowledge is certainly awful. This paper aims at making a critical analysis how product data evolve throughout the product design or configuration process and how they impact the product development activities. Efficient digital product twin allows companies to virtualize processes and leverage their automation, but it is important to understand how the knowledge management should be carried out. Three case studies, directly experienced by the authors, have been investigated analyzing digital data and virtual tools that allow companies to automate the design process, each one bringing a peculiar perspective of the problem.

Creativity can be viewed as a chaotic or unplanned activity. The product design process often may seem like chaos as well, but this is not inevitable. Designers and human factors/ergonomics (HF/E) professionals follow a clear design process with phases, levels, and methods for creation of successful new products. Research methods are offered at the right time during this process to generate new concepts and to evaluate designs. We work together to create innovative, valued, and successful products via a generative, iterative, evaluative process.

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.

Information systems are key enablers for the integration and reliable management of the product development process. Information systems are the backbone that connects various sub-processes and enables flexible product customization. Fast, robust, and cost-efficient product adaptation is especially important in one-of-a-kind production. This paper presents a transformation of the product development design process for large power transformers into a competitive and smartly supported process. One-of-a-kind production is specific, as each product must be customized, wherefore a robust design process well supported by IT plays a key role in creating a digital twin and the product’s final value. Based on a systematic analysis of the sample company, this paper proposes a model for the complete renewal of information systems and of working methodology, where reorganization is demonstrated in an increase of overall effectiveness.

As we enter the third millennium, many organizations are forced to constantly pursue new strategies to differentiate themselves from their competitors. Examples include offering customers streams of new products and services, as well as continuously seeking to improve productivity, services and the effectiveness of product design, development and manufacturing processes. Consequently, new concepts, approaches and tools are emerging quickly as the globalization trend expands across the world. Product complexity, pressures to reduce production cycle time, the need for stakeholders’ contributions and multinational company as well as consumer requirements create the demand for sophisticated multi-designer collaborative virtual environments where product design can be shared and acted upon (Kunz, Christiansen, Cohen, Jin, & Levitt, 1998; Ragusa & Bochanek, 2001; Anderson, Esser & Interrante, 2003). Thus, researchers and practitioners recognize that collaboration is an essential aspect of contemporary, professional product design and development activities. The design process is collaborative by nature. Collaborative design fosters participation of stakeholders in any form during the design process. The design of a successful product is dependent on integrating information and experiences from a number of different knowledge domains. These domains include consumer (end-user) requirements, industrial designers’ professional design skills as well as manufacturers’ needs. This results in a product that performs at a functional as well as aesthetic level and that can be manufactured by the right process at the right price. End-user involvement is essential to product design, since products that do not achieve consumer satisfaction or meet consumer needs are doomed to fail (Schultz, 2001). Accurate understanding of user needs is an essential aspect in developing commercially successful products (Achilladelis, 1971). Hence, it is very important for industrial designers to gather the end-users’ needs and incorporate them into their designs. The involvement of manufacturers in the initial stages of the domestic product design process can lead to a dramatic reduction in a product’s development lifecycle time, also facilitating the coordination of the purchasing and engineering functions (Bochanek & Ragusa, 2001; Demirbilek, 2001). The increasing complexity of artifacts and the globalization of product development are changing research methodologies and techniques. A prime example of this includes the application of a virtual collaborative design environment (VCDE) for product design and manufacturing. This article focuses on the concept of virtual collaborative design. It describes a research effort to investigate cross-cultural collaboration in product development using online applications for domestic product design. The aim of this research is to investigate issues related to the virtual collaborative design (VCD) process, and to bring an understanding of stakeholder needs during the collaborative design process as well as to improve the relationships between end-users, designers and manufacturers. The article presents findings based on a survey study conducted with four different potential stakeholders: representatives of consumers, software designers, industrial designers and manufacturers.
