Iterative Design

Establishing product requirements for the customer is usually the first step in the product development process. Indeed, identifying and fulfilling customer requirements is the key for successful product development. However, satisfying all the customer requirements is not always possible. Therefore, the best design is the design that fulfils a set of the most important customer requirements. Due to this, design process needs to be agile and iterative. Design and its requirements need to be effectively iterated.

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.

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.

Discrete Differential Evolution

The scheduling of the design activities in product development process is a crucial step in early stages in order to achieve the project in time and cost-effective manner. In complex product development process, many dependency relationships or feedback loop could exist between design activities with multiple technical domains. Sequencing the design activities is a decision making process in order to reduce these feedback loops, and therefore, reduce amount of required information flows between activities. In recent years, methods for sequencing the design activities in design process have been proposed in order to reduce lead-time development and cost. The purpose of this research work is to present a methodology for design process sequencing in product development project by using Design Structure Matrix (DSM) for visualization a complex process and Discrete Differential Evolution (DDE) for sequencing the design tasks. The tests performed in this article have shown that this approach provides very competitive results in term of the quality of obtained solutions when compared to Genetic algorithms (GA). In additional it is a simple, effective and easy to use since the amount of control parameters to set is reduced.

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.

New Strategy

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.

Product Design Process

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.

Holistic View

Design optimization is becoming and increasingly important tool for design. In order to have an impact on the product development process it must permeate all levels of the design in such a way that a holistic view is maintained through all stages of the design. The design process can be viewed as a process of increasing the information of the finished product. Design optimization is on one hand a part of the design process, but can also be used as a metaphor for the whole design process. In this paper an information theoretical approach is taken to establish a performance criterion for an optimization method. Furthermore, this approach is extended do describe the design process.

This case describes the redesign of a mobile eReader application. The purpose of the redesign was to convert an existing eReader from a means of only reading books into a tool for informal learning. The case reports how the design team’s definition of informal learning evolved throughout the product development process, and how design deci-sions were influenced by this changing definition. Over the period of time covered in the case, the eReader evolved from a tool used for reading eBooks, into one meant for personal study, and then into a product that supported serendipitous discovery of inspiring material (built under a philosophy that informal learning meant that people were able to discover interesting and uplifting material without exerting effort to find it). The end point of the eReader’s evolution was as a subscription service for the company’s eBooks and digital audiobooks, to allow customers to continually use them for educational purposes. This case is structured around the four iterations of the eReader design process. Each iteration reports how design decisions were made and what kind of results were achieved.

Research efforts in lean design are usually focused on enabling lean manufacturing or managing the product development processes. Very few efforts, however, have been directed towards the design process itself. While the most successful lean applications started with the manufacturing process, due to its nature and the ability to identify the process wastes, the full impact of lean thinking can only be achieved when applied at the beginning of the product development process starting with early design phases. Considering that the first and most fundamental principle in lean thinking is to realize value from the customer’s perspective, it is essential that a lean product development process implementation assures the flow of this value throughout the process. This can only be accomplished when lean principles, tools, and methodologies are utilized in all phases from concept development in the design phase to manufacturing in the production phase. In this paper, the utilization of lean principles, tools, and methodologies during the design process is discussed. In addition, the adaptation of several lean tools and methodologies to assist in applying the lean principles throughout the different phases of the design process is demonstrated. To illustrate the concepts, adaptation process, and implementation some examples are presented.
