The understanding of customer preference, in relation to product attributes, is a key challenge in industrial design. It is based on preference measurement, which is a complex task, crucial for sound design decisions. In this paper, we study experimentally the influence of the preference elicitation method on the results of the test. For this, we designed a case study concerning the perception of vehicle’s front-end by a panel of subjects. Two different preference elicitation methods were used in the same session: direct rating on a scale, and pairwise comparison. Conjoint Analysis was used next to model the preference and to compute the part worth of the different design factors. Two conjoint methods were examined: rating based and choice based. The paper presents a comparison of the results of the different modeling with conjoint analysis, in order to assess the reliability and the validity of the models.

Abstract For SRAMs with high logic complexity, hard defects, design debug, and soft defects have to be tackled all at once early on in the technology development while innovative integration schemes in front-end of the line are being validated. This paper presents a case study of a high-complexity static random access memory (SRAM) used during a 32nm technology development phase. The case study addresses several novel and unrelated fail mechanisms on a product-like SRAM. Corrective actions were put in place for several process levels in the back-end of the line, the middle of the line, and the front-end of the line. These process changes were successfully verified by demonstrating a significant reduction of the Vmax and Vmin nest array block fallout, thus allowing the broader development team to continue improving random defectivity.

Multiple Case

The front end of projects is strategically important; yet, how project concepts are identified, evaluated, and selected at the pre-project stage is poorly understood. This article reports on an inductive multiple-case study of how executives made such decisions in major upstream oil and gas projects. The findings show that in such a high-risk context, often an experienced executive makes these decisions alone and he creates value by facilitating growth. We identified three value-creating decision processes that varied by the executives’ risk approach and decision context. These processes depart from the formal project management prescriptions and the strategic decision-making literature.

This paper presents a systematic function recommendation process (FRP) to recommend new functions to an existing product and service. Function plays a vital role in mapping user needs to design parameters (DPs) under constraints. It is imperative for manufacturers to continuously equip an existing product/service with exciting new functions. Traditionally, functions are mostly formulated by experienced designers and senior managers based on their subjective experience, knowledge, creativity, and even heuristics. Nevertheless, against the sweeping trend of information explosion, it is increasingly inefficient and unproductive for designers to manually formulate functions. In e-commerce, recommendation systems (RS) are ubiquitously used to recommend new products to users. In this study, the practically viable recommendation approaches are integrated with the theoretically sound design methodologies to serve a new paradigm of recommending new functions to an existing product/service. The aim is to address the problem of how to estimate an unknown rating that a target user would give to a candidate function that is not carried by the target product/service yet. A systematic function → product recommendation process is prescribed, followed by a detailed case study. It is indicated that practically meaningful functional recommendations (FRs) can indeed by generated through the proposed FRP.

Relevant Factors

Purpose The purpose of this paper is to explore the relevant factors that influence the implementation of innovation contests, an open innovation (OI) practice that has been extensively reported in the literature as a managerial tool for external knowledge search. The authors focus the study on the context of small and medium enterprises (SMEs). Design/methodology/approach The approach is a retrospective case study. This methodology allows an in-depth view into a Spanish SME that successfully undertook two new product development processes thanks to the deployment of innovation contests. Findings The main context factors influencing innovation contests as managerial tool are ambidexterity, technological and marketing turbulence and intermediaries, among others. Regarding design factors, this work highlights the role of attraction and facilitation. Additionally, the repetitive implementation of innovation contests creates a corporate culture that promotes OI activities. Practical implications Managers will understand that they can use innovation contests as a managerial tool, and knowing the factors that need to be taken into account when implementing an innovation contest will help SMEs managers to make better use of this practice. Originality/value This case study enriches the literature of both innovation contests and topics relevant to SMEs. Based on a theoretical framework of the design factors that influence the implementation of innovation contests, the authors propose a research framework that incorporates those context factors in association with an SME.

Torsion Stiffness

The torsion stiffness of an automotive chassis can be determined using an analytical approach based purely on geometry, using an experimental method, or alternatively by employing a Finite Element Analysis (FEA) process. These three methods are suitable at different design stages and combined together could prove to be practical methods of determining the torsion stiffness of a chassis. This paper describes and compares two distinct FEA processes to determine the torsion stiffness of an automotive chassis during the detailed design stage. The first process iteratively applies forces to the model and records displacements, while the second process gradually applies vertical displacements in place of force to determine the torsional stiffness threshold. Each method is explained and supported with a case study to provide a basis of comparison of the results.

The article presents the results of the study of satisfaction with the psycho-didactic component of the educational environment as an indicator of threats to the psychological health of schoolchildren in three groups: parents, teachers and heads of educational organizations. The total number of respondents in the sample was 16,808 people. Satisfaction with the educational environment in the following characteristics was studied: satisfaction with 1) the content of education, 2) the conditions of training, 3) the techniques of training and education used in educational organizations. A pairwise comparison of the results obtained in three groups of respondents revealed statistically significant differences in all characteristics. At the same time, parents showed the highest degree of satisfaction with the psycho-didactic component of the educational environment, which may be due to their insufficient involvement to the educational process and incomplete awareness of the real situation in the schools. Teachers and school heads are less satisfied with the psycho-didactic component of the educational environment and therefore see more risks and threats to the psychological health of children.
