A Customer-based Approach for Selecting Attributes and Levels for Preference Measurement and New Product Development
by Michael Steiner, Roland Helm, Verena Huettl-Maack
Abstract: Preference measurement is commonly used to identify customer needs and to create products that satisfy these needs. Over the past few decades, most researchers have focused on developing new survey or estimation methods. However, researchers were paying little attention to the selection of attributes and levels for preference measurement. This study provides an overview of the common methods currently in use to define attribute sets for conjoint analysis, and it extends previous research by proposing an evoked setbased attribute selection method (EVAS). The EVAS is intended to aid the selection of appropriate attributes and levels by focusing on products that are acceptable from the consumers perspective. An empirical study of this approach reveals that the applicability of attribute sets increases, and implausible estimates can be avoided.

Proposal for a Process oriented Knowledge Management System (PKMS)
by Ludovic Louis-Sidney, Vincent Cheutet, Samir Lamouri
Abstract: In an increasingly competitive environment, manufacturing companies are more frequently looking to handle the knowledge referentials relating to their redesign processes. They are then able to implement this with less effort and balance out their work capacity for innovation activities, contributing to more significant improvements in their product offering. In this article we propose a conceptual model for the implementation of a process-oriented knowledge tool dedicated to the formalization of this type of knowledge referential. The implementable nature of this model has been validated by a demonstrator tested on an application case provided by our industrial partner, Renault Powertrain Technology Department.

Extending the Functional Products definition with additional through-lifecycle aspects
by John Lindstrom
Abstract: The paper provides a comprehensive overview on which through-lifecycle aspects of Functional Products (FP) are relevant to consider during development and later operation until end-of-life. The aspects, which are already proposed as part of the current definition of FP, are corroborated, and the additional new aspects found are proposed to extend the current definition of FP. An additional eight new aspects have been found, spanning, e.g., asset management, business model and research collaboration. Some of these new aspects may be relevant for the concepts of Servitization, Through-life Engineering Services, Product-Service Systems and Industrial Product-Service Systems as well.
The practical implications of the results are that FP customers can improve their reasoning and requirement engineering together with FP providers. FP providers can, on the other hand, use the results to improve their long-term planning and activities from initial development activities (i.e., business case and requirement engineering) to operation at customer sites. The theoretical implications are that the additional new aspects and the proposed extended FP definition provide a foundation for researchers as well as indicating aspects/areas to further explore.
Keywords: definition, development, Functional Products (FP), lifecycle, operation, through-lifecycle aspects.
Apparel product development: an overview of existing models
by Niromi Seram, Julian Nanayakkara, Gamini Lanarolle
Abstract: The product development process is recognized as a key element for ensuring long term success and sustainability of organizations. Constantly re-evaluating the strategy and tactics of product development is deemed to be vital to better manage the process of creating more on-point products. Thus, the main focus of this research is to assess how deeply and comprehensively the existing apparel product development models outlined in literature discuss and analyze the development process and identify the prevailing gaps that exist with respect to customer-supplier collaboration and decision making.
Some of the existing models discussed in depth in the reported research are, design, design development and style selection stages. A few have considered the integration of the responsible divisions. The theoretical models presented in the literature have not adequately addressed the customer-supplier collaboration and the decision making involved in the apparel product development process although many of them focused on the activities undertaken to complete the product development.
Keywords: product development, apparel, customer-supplier collaboration, decision making models.
