The Impact

The purpose of this paper is to explore how a recently developed method for evaluation of the impact of assembly complexity on manual assembly concepts should be used, by whom and how this would fit into an industrial product development process. The explored method incorporates both sensitivity to geometrical variation and assessment of assembly complexity and is integrated into the CAT (Computer Aided Tolerancing) tool RD&T. A baseline of a generic six phase product development procedure is summarized with focus on the part of the process that handles geometry assurance; the geometry assurance process. The result is a proposed working procedure for proactive geometry assurance considering manual assembly complexity as a part of a geometry assurance process. The proposed working procedure supports the development of products that have a high level of geometrical robustness and a low level of manual assembly complexity resulting in higher quality, less costs related to poor quality and less waste. Need for further research is also identified since the current tools for assessing manual assembly complexity do not support all geometry assurance activities needed. One suggestion is to expand the current calculation models to interact with the variation analysis in CAT through assembly tolerances.

The Impact

In this paper we present a starting point for designing for and/or assessing the social impact of engineered products. The starting point is a set of tables comprising products, their general functional characteristics, and the accompanying social impacts. We have constructed these tables by first extracting a set of social impact categories from the literature, then 65 products were qualitatively reviewed to find their social impact. The resulting product impact tables can be used at either the beginning of the product development process to decide what social impact to design for and discover product functions that lead to it, or later to qualitatively assess the social impact of a product being designed and/or to assess the impact of an existing product.

The Impact

Even though the literature on product and process development is extensive, not much attention has been devoted to categorizing the product development process itself. Existing work on product development processes such as Total Design, Integrated Product and Process Design among others advocate common approaches that should be followed throughout the organization, without any consideration of product characteristics. In this paper we review several existing development methodologies. Extensions of these are categorized by their applicability to different classes of products. We propose that development processes should be matched to product attributes and organization goals. Towards this end, we associate development processes along with their components such as House of Quality, Robust Design, TRIZ etc. with goals such as time to market, customer needs satisfaction, intellectual property generation, protection and exploitation, quality, product cost and others. We examine the impact of this association on the development process itself and propose guidelines for constructing specific processes associated with one or more goals. Tools and benchmarks for various applications are discussed, along with some case studies on the design of different development processes.

Original Concept

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.

Project Level

Many current models of the product development process pay insufficient attention to the impact of project-level influences. This paper looks at the case of the engineering industry in which product development is seen to proceed in two very distinct ways: the traditional process in which development takes place "off-line", and the contract process in which development takes place as part of a contract to manufacture a product for a specific customer. Drawing on two recent studies of engineering product development projects, the paper looks at how project-level influences lead to differences in project organisation and management in terms of the particular project structure adopted and in the involvement of different disciplines, internal and external to the company. This has implications for the way in which companies should interpret generic prescriptions regarding product development.

The Impact

Product development is important more than ever for manufacturing firms. A well-designed performance measurement system can assess the impact of product development on the whole company. Such a system can also be utilized for motivating employees, especially product development staff. Naturally, a set of suitable product development measures can provide valuable information for managing the activities and continuous improvement of the product development process. In this paper, via our literature review, we first establish that “a suitable set of performance measures” to assess product development performance is not readily available. Then, we identified performance criteria for assessing product development process effectiveness based on competitive priorities (cost, quality, flexibility, delivery and innovation) followed by ANP analysis. Finally, using a two tier survey setting, the validity and reliability of the criteria set were ascertained, and field data for its (performance measure set) usage as an assessment tool for product development is demonstrated. The field study was conducted by participation of a sample of manufacturing companies in Turkey.

New Product Development Process

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 Impact

A mechanical behavioural analysis can be useful at different stages of the product development process, and there are different scenarios where a FE (Finite Element) analysis can support the design phase. Unfortunately, preparing a model suitable for the FE analysis and solving a FE problem are time expensive and need a considerable involvement of simulation experts. In this paper, we analyze several scenarios of product development process, where an a posteriori criterion allows exploiting some existing FE analysis results. Their common denominator stands in the evaluation of the impact of the component shape modifications on the accuracy of existing FE results, by means of an a posteriori FE error indicator. It is computed using the stress and strain fields over the component. This indicator is targeted to determine whether a shape sub-domain has some influence over pre-existing FE analysis results, i.e. whether an accurate FE analysis needs to use a model including this sub-domain. Here, we will describe the input and output parameters of our a posteriori indicator and what are the requirements for its incorporation in the different scenarios. Each of the proposed scenarios will be analyzed and illustrated to identify its potentials and requirements.

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.
