Product Families

Due to rapid changes in end-user requirements and vast improvements in technology, many product development companies identified strategies like time-to-market (TTM) compression and product family development as critical for attaining success in today’s hyper-competitive environment. Further, the companies are increasingly investing on involving suppliers in various activities of a product realization process. The present paper facilitates this trend of the market by adopting supplier involvement in product design phase. Product design phase has been chosen because 70–80% of the product cost is locked in during this phase. A methodology for optimal supplier network formation is proposed so that the product development projects are completed on time and on budget, while catering to the evolving end-user requirements over a given planning horizon. The present methodology selects the detail design of the product families while forming the supplier network. In this methodology, apart from cost and time, inter-supplier communication has been modeled as one of the supplier selection criteria. This criterion is based on the effect of product architecture on integrator-supplier-supplier communication and the nature of supplier organization. The present problem has been illustrated using the case example of insulin delivery device product families and the proposed methodology has been solved using a goal programming approach.

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.

Abstract Mass customization is becoming an important agenda in industry and academia alike. This paper deals with mass customization from a product development perspective. A framework of design for mass customization (DFMC) by developing product family architecture (PFA) is presented. To deal with tradeoffs between diversity of customer requirements and reusability of design and process capabilities, DFMC advocates shifting product development from designing individual products to designing product families. As the core of DFMC, the concept of PFA is developed to assist different functional departments within a manufacturing enterprise to work together cohesively. A PFA describes variety and product families and performs as a generic product platform for product differentiation in which individual customer requirements can be satisfied through systematic decisions of developing product variants. Based on such a PFA, the DFMC framework provides a unifying integration platform for synchronizing market positioning, soliciting customer requirements, increasing reusability, and enhancing manufacturing scale of economy across the entire product realization process.

AbstractIn the design phase of product development (PD) process, most new products face significant uncertainties and risks. Uncertainty is typically associated with a lack of information, while learning is a process that acquires information. Therefore, learning fast and at low cost decreases the uncertainty and increases the efficiency of the product design phase. This paper investigates the concept of the cost of learning in PD's design phase. Reviewing the literature, we conceptualize the cost of learning and review the learning methods considering three aspects in the design phase of the PD process: (1) costs associated with learning from mistakes and failures, (2) learning methods and (3) categories of learners. This paper thus provides the conceptual foundations for future work to increase the efficiency of the PD process by reducing the cost of learning from mistakes and failures.

Increase of demand on product variety has pushed companies to think about offering more and more product variants in order to take more market shares. However, product variation can lead to cost increase for design and production, as well as the lead time for new variants. As a result, a proper tradeoff is required between cost-effectiveness of manufacturing and satisfying diverse demands. Such tradeoff has been shown to be manageable effectively by exploiting product family design (PFD) and platform-based product development. These strategies have been widely studied during the past decades, and a large number of approaches have been proposed for covering different issues and steps related to design and development of product families and platforms. Verification and performance of such approaches have also been traced through practical case studies applied to several industries. This paper focuses on a review of the research in this field and efforts to classify the recent advancements relevant to product family design and platform development issues. A comprehensive review on the state-of-the-art research in this field was done by Jiao et al. in 2007; therefore the main focus of this paper is on the research activities from 2006 to present. Mainly, the effort of this paper is to identify new achievements in regard with different aspects of product family design such as customer involvement in design, market driven studies, new indices and metrics for assessing families and developing the desired platforms, issues relevant to product family optimization (i.e., new algorithms and optimization approaches applied to different PFD problems along with their benefits and limitations in comparison to previously developed approaches), issues relevant to development of platforms (i.e., platform configuration approaches, joint platform design and optimization, and factors effective on forming proper platform types), and issues relevant to knowledge management and modeling of families and platforms for facilitating and supporting future design efforts. Through a comparison with previous research, new achievements are discussed and the remaining challenges and potential new research areas in this field are addressed.

Product Platforms

In an effort to improve customization for today's highly competitive global marketplace, many companies are utilizing product families and platform-based product development to increase variety, shorten lead times, and reduce costs. The key to a successful product family is the product platform from which it is derived either by adding, removing, or substituting one or more modules to the platform or by scaling the platform in one or more dimensions to target specific market niches. This nascent field of engineering design has matured rapidly in the past decade, and this paper provides a comprehensive review of the flurry of research activity that has occurred during that time to facilitate product family design and platform-based product development for mass customization. Techniques for identifying platform leveraging strategies within a product family are reviewed along with metrics for assessing the effectiveness of product platforms and product families. Special emphasis is placed on optimization approaches and artificial intelligence techniques to assist in the process of product family design and platform-based product development. Web-based systems for product platform customization are also discussed. Examples from both industry and academia are presented throughout the paper to highlight the benefits of product families and product platforms. The paper concludes with a discussion of potential areas of research to help bridge the gap between planning and managing families of products and designing and manufacturing them.

Many companies constantly struggle to find cost-effective solutions to satisfy the diverse demands of their customers. In this paper, we report on two recent industry-focused conferences that emphasized platform design, development, and deployment as a means to increase variety, shorten lead-times, and reduce development and production costs. The first conference, Platform Management for Continued Growth, was held November–December 2004 in Atlanta, Georgia, and the second, 2005 Innovations in Product Development Conference — Product Families and Platforms: From Strategic Innovation to Implementation, was held in November 2005 in Cambridge, Massachusetts. The two conferences featured presentations from academia and more than 20 companies who shared their successes and frustrations with platform design and deployment, platform-based product development, and product family planning. Our intent is to provide a summary of the common themes that we observed in these two conferences. Based on this discussion, we extrapolate upon industry’s needs in platform design, development, and deployment to stimulate and catalyze future work in this important area of research.

Emerging Issues

To address emerging issues due to global product development and shortening product development cycles, we propose a modular product design methodology using interface-based module descriptions published through cyber-infrastructure. In this paper, we describe (1) a general way of defining interfaces, partially utilizing a standardized language of product functionality known as the Functional Basis, (2) a formal way of representing components in eXtensible Markup Language that defines a new Module Description Language (MDL), and (3) the application of the proposed methodology to the design of a product family of electronic screwdrivers, a mechanical product, extending previous work with electrical products.

Design Concepts

Many companies strive to maximize resource utilization by sharing and reusing distributed design knowledge and information when developing new products. By sharing and reusing assets such as components, modules, processes, information, and knowledge across a family of products and services, companies can efficiently develop a set of differentiated products by improving the flexibility and responsiveness of product development (Simpson, 2004). Product family planning is a way to achieve cost-effective mass customization by allowing highly differentiated products to be developed from a shared platform while targeting products to distinct market segments (Shooter et al., 2005). In product design, data mining can be used to help identify customer needs, to find relationships between customer needs and functional requirements, and to cluster products based on functional similarity to facilitate modular design (Braha, 2001). The objective in this chapter is to introduce a methodology for identifying a platform along with variant and unique modules in a product family using design knowledge extracted with data mining techniques. During conceptual design, data mining can facilitate decision-making when selecting design concepts by extracting design knowledge and rules, clustering design cases, and exploring conceptual designs in large product design databases interactively (Braha, 2001). Moreover, since design knowledge for a product depends on the experience and knowledge of designers, representation of design knowledge, such as linguistic representation, may fail to describe a crisp representation completely. When clustering design knowledge, the knowledge is needed to assign to clusters with varying degrees of membership. Fuzzy membership can be used to represent and model the fuzziness of design knowledge (Braha, 2001). Design knowledge can be defined as linguistic variables based on the fuzzy set theory to support decision-making in product development (Ma et al., 2007).

Purpose Modular product development is a turning table concept in terms of benefits and impact in manufacturing companies. It offers added benefits to the companies with respect to reduce lead-time, improve assemble ability and agility in supply chain management, promote product family and enhance customer satisfaction. This paper aims to identify the patterns of modular product development strategy by using measurement techniques. Design/methodology/approach Both quantitative and qualitative approaches are considered. In the qualitative section, relevant data on product design are collected from six case companies. On the other hand, in the quantitative section, collected data are analyzed to measure the product modularity level with the case companies. Findings This research identifies potential metrics which can be used successfully to measure product modularity level or index in manufacturing industries. Selection of such metrics also depends on individual company’s objectives to measure modularity index. Originality/value This research contributes to the development of modular product design that supports product family design with lean and agile (leagile) supply chain process. It also provided a parsimonious framework to mapping modules within a product, which is ultimately used to measure modularity index.
