This paper analyzes the impact of 3D model annotations on CAD user productivity in the context of the New Product Development Process. These annotations can provide valuable information to support an improved design intent communication. Comparably, they can play the same role as source code comments to support code maintainability in software engineering. A 3D CAD model is a geometry representation and it also stores the modeling strategy used to build it. Alteration of a complex CAD model usually represents a time consuming task due to the lack of an explicit explanation of the design rationale followed to build that 3D model. An experimental study conducted with Spanish and Mexican CAD students indicates that it is possible to reduce the time needed to perform engineering changes in existing models by between 13–26% by using annotations. Also some factors that affect the impact of annotations on the engineering change process such as part and alteration complexity were identified.

In modern industry, the development of complex products involves engineering changes that frequently require redesigning or altering the products or their components. In an engineering change process, engineering change requests (ECRs) are documents (forms) with parts written in natural language describing a suggested enhancement or a problem with a product or a component. ECRs initiate the change process and promote discussions within an organization to help to determine the impact of a change and the best possible solution. Although ECRs can contain important details, that is, recurring problems or examples of good practice repeated across a number of projects, they are often stored but not consulted, missing important opportunities to learn from previous projects. This paper explores the use of Self-Organizing Map (SOM) to the problem of unsupervised clustering of ECR texts. A case study is presented in which ECRs collected during the engineering change process of a railways industry are analyzed. The results show that SOM text clustering has a good potential to improve overall knowledge reuse and exploitation.

Approximately half of new product development projects fail in the market place. Within the product development process, prototyping represents the largest sunk cost; it also remains the least researched and understood. While researchers have recently started to evaluate the impact of formalized prototyping methods and frameworks on end designs, these studies have typically evaluated the success or failure of these methods using binary metrics, and they often evaluate only the design’s technical feasibility. Intuitively, we know that a product’s success or failure in the marketplace is determined by far more than just the product’s technical quality; and yet, we have no clear way of evaluating the design changes and pivots that occur during concept development and prototyping activities, as an explicit set of rigorous and informative metrics to evaluate ideas after concept selection does not exist. The purpose of the current study was to investigate the discriminatory value and reliability of ideation metrics originally developed for concept generation as metrics to evaluate functional prototypes and related concepts developed throughout prototyping activities. Our investigation revealed that new metrics are needed in order to understand the translation of product characteristics, such as originality, novelty, and quality, from original concept through concept development and prototyping to finalized product.

Most of the product design on the market is variant design or adaptive design, which need to reuse existing product design knowledge. A key aspect of reusing existing CAD model is correctly define and understand the design intents behind of existing CAD model, and this paper introduces a CAD model annotation system based on design intent. Design intents contained all design information of entire life cycle from modeling, analysis to manufacturing are marked onto the CAD model using PMI module in UG to improve the readability of the CAD model. Second, given the problems such as management difficulties, no filter and retrieval functions, this paper proposes an annotation manager system based on UG redevelopment by filtration, retrieval, grouping and other functions to reduce clutter on the 3D annotations and be convenient for users to view needed all kinds of annotations. Finally, design information is represented both internally within the 3D model and externally on a XML file.

Taking into account the customers, supplier and organization involvement in the new product development (NPD), this article focuses on the synthesis, evaluation, and selection of various sub-factors of concurrent engineering involved in new product development process. The aim of this study was to provide the reliability and validity of six sub-factors of concurrent engineering model of the 49-item questionnaire and to analyze its association with concurrent engineering and new product development process in a sample of 35 manufacturing and services organization located in Johor, Malaysia. Methods: A self reported survey was conducted in 35 manufacturing and services organization located in Johor, Malaysia. Results: Appropriate internal consistencies of the six sub-scales: customers relationship, team development, continuity, tools and techniques, suppliers involvement and corporate focus and their association with concurrent engineering, were obtained. Zero-order correlation and regressions analysis replicated the theoretically assumed structure of the effective concurrent engineering (ECE). Evidence of criterion validity was obtained from cross-correlations of the scales and from their linear and multiple regression analysis. Finally, all seven scales were associated with a highly significant ratio of concurrent engineering as predicted by fundamental theory. Conclusion: Based on the results of this study the seven version of the model, questionnaire is considered a reliable and valid instrument for measuring association in developing the new complex product development process.

The purpose of this article is twofold. First is to ascertain and establish the collaboration required between different stakeholders in the fundamental process of New Product Development (NPD). Augmentation of the process with the IoT origin real time data to enrich the efficacy of the New Product Development process forms the second part of the study. The primary data is collated from over 100 plus professionals while the qualitative data required for the second part is collated with the help of focused group interviews. The Likert scale with five points was deployed to record the opinions. The empirical analysis supports the theory that an effective collaboration is required between the different entities such as Sales, Marketing, R&D and going beyond the organizational boundaries Suppliers & Customers for the new product to be fruitful and successful in the market. The impact of using the IoT origin real time data on the effectiveness of the New Product Development is evaluated. In the current scenario for an organization to lead the market, it is essential that it has a descent product roadmap and an effective NPD. The current study reveals the importance of the NPD and contributes towards making it more effective with the IoT origin real time data.

The utilization of crowdsourcing to acquire distant knowledge is increasing. In the new product development process, sustainable crowdsourcing is an effective way to exploit both external and internal resources to boost enterprise innovation quality and the efficiency of the competitive edge of macro tasks in a relatively long cycle. The challenge of sustainable crowdsourcing is how to design a proper incentive mechanism to achieve the maximum initiator profit and, at the same time, satisfy the solver’s motivation so that they can continuously participate in the innovation process. In two situations, including a single motivation and multiple motivations of the solver, this paper analyzed the impact of a few factors on the initiator’s profit and the incentive coefficient for the solver based on the Principal–Agent Model. From the model and simulation results, the solver’s incentive coefficient is positively correlated to the solver’s work quality and negatively correlated to the uncertainty of the enterprise operation, the solver’s Effort Cost, the solver’s degree of risk aversion, etc. If the initiator is more sensitive to the benefits of the solver’s intrinsic motivation, the monetary incentive will be higher. The research results provide a theoretical basis to quantify the initiator’s expected profit and design a proper incentive plan for the solver. Finally, the conclusions offer practical guidance for enterprise to execute incentive plans for sustainable crowdsourcing from the perspective of the solver’s motivation.

Engineering changes are inevitable in a product development life cycle. The requests for engineering changes can be due to new customer requirements, emergence of new technology, market feedback, or variations of components and raw materials. Each change generates a level of impact on costs, time to market, tasks and schedules of related processes, and product components. Change management tools available today focus on the management of document and process changes. Assessments of change impact are typically based on the “rule of thumb”. Our research has developed a methodology and related techniques to quantify and analyze the impact of engineering changes to enable faster and more accurate decision-making in engineering change management. Reported in this paper are investigations of industrial requirements and fundamental issues of change impact analysis as well as related research and techniques. A framework for a knowledge-supported change impact analysis system is proposed. Three critical issues of system implementation, namely integrated design information model, change plan generator and impact estimation algorithms, are addressed. Finally the benefits and future work are discussed.

This chapter contributes to a better understanding of the role of social media in the NPD process and a debate about the impact of social media on NPD success. Through a critical literature review, this chapter provides an insight into the impact of social media on incremental NPD and its contribution to NPD success, in the context of customer involvement. The review is mainly derived from 286 relevant papers published in top-ranked journals between 2005 and 2014. The results suggest that while social media provides an effective and efficient method for collecting information and knowledge about customers' expectations and experiences, it does not necessarily always lead to NPD success. The study shows that hidden customer needs, an advanced evaluation tool, the huge amount of information and a firm's absorptive capacity challenge the use of social media.
