The incessant improvements in IC technology have made it possible to conceptualize “information appliances” providing nearly unimaginable scalar, vector, and massively parallel information processing capability in small and relatively cheap computing platforms. The successful commercialization of such systems requires substantially shortened “time-to-market”, as well as dramatically reduced cost-of-ownership, and places extraordinary demands on packaging and physical design. A science-based physical design methodology, which can guide the development, selection, and evaluation of advanced packaging technology, will be needed to generate these sophisticated products. Mechanical engineers must play a major role in replacing the conventional “trial and error” development process with a science-based design methodology.

Purpose This paper aims to outline the prosocial leadership development process for guiding pedagogical and social justice course goals as a means to foster prosocial leadership values within the millennial generation. Design/methodology/approach The paper is guided by a social justice framework and proven classroom pedagogies as a means to align millennial characteristics within the four stages of the prosocial leadership development process. Findings An educational rubric is provided as a means to guide classroom pedagogies, course goals and millennial characteristics through a prosocial leadership development process. Research limitations/implications The paper is conceptual in nature, and therefore, theoretical correspondence remains speculative. Practical implications The research in this paper provided guidelines for educators to use pedagogical practices as a means to develop prosocial values as a basis for organizational leadership behaviors. Social implications This leadership development process when facilitated through proven pedagogical techniques (guided by established social justice curriculum goals) and is within the context of millennial characteristics (those born between the years 1982 and 2005) becomes catalytic in empowering leaders to be a remedy for the world’s environmental and social challenges. Originality/value This paper connects characteristics of millennials to a prosocial leadership development model.

This paper presents an optimization methodology for designing radiant enclosures containing specularly-reflecting surfaces. The optimization process works by making intelligent perturbations to the enclosure geometry at each design iteration using specialized numerical algorithms. This procedure requires far less time than the forward “trial-and-error” design methodology, and the final solution is near optimal. The radiant enclosure is analyzed using a Monte Carlo technique based on exchange factors, and the design is optimized using the Kiefer-Wolfowitz method. The optimization design methodology is demonstrated by solving two industrially-relevant design problems involving two-dimensional enclosures that contain specular surfaces.

Abstract As companies become aware that they have to restructure their product development processes to survive global competition in the market, it is important that they evaluate which management methods and techniques are suitable to improve the performance of the process and which design methods can be integrated and be used efficiently. A combination of management methods like Total Quality Management (TQM), Simultaneous or Concurrent Engineering, and Lean Development can be adapted to meet the requirements of a company more than a single strategy. Interdisciplinary teamwork, cross-hierarchical communication, and delegation of work in addition to employee motivation changes the common attitude towards the work process in the company and integrates the staff more tightly into the process. Nowadays, there is tight cooperation between companies and their sub-contractors, as sub-contractors not only have to manufacture the part or sub-assembly, but often have to design it. Therefore, the product development process has to be defined in a way that the sub-contractors can be tightly integrated into the product development process. Additionally, it is important to break the product down into functionally separate modules during the conceptual phase of the process. If the interfaces between these functions are defined as specifications, these modules can easily be given to suppliers or to other teams inside the company for further development. The use of methods such as Design for Manufacture (DFM) or Design for Assembly (DFA) early during the development process, which utilize the knowledge of experts from manufacturing and assembly, results in a decreasing number of iterative loops during the design process and therefore reduces time-to-market. This cross-functional cooperation leads to improved quality of both processes and products. In this paper, different management methods to achieve the best improvement from the product development process are discussed. In addition, suitable design methods for achieving cost reduction, quality improvement, and reduction of time-to-market are presented. Finally, proposals for industry on methods to reorganize the Integrated Product Development (IPD) process based on actual findings are presented.

Abstract Advanced packages are necessary to cope with the requirements of 5G and radar technologies with 60 GHz and beyond. For proper RF design with rising package technology requirements demands for usage of predefined structures with predefined layout elements, manufactured and measured elements. This paper deals with an approach to have such elements available to build advanced types of packages in shorter time compared to classical approaches. The approach is a general approach but it is demonstrated with an advanced two-level package-on-package technology with a leading edge IC technology. It is also used explain the build-up of a construction kit of RF-blocks from the design phase of test structures up to measurement of such structures, qualification and model building. From the test structure more general structures can be derived and used in the design of future 5G applications. This enables better time-to-market, reduces cost and provides higher design validation in terms of first time right.

Purpose The article offers an innovative process for collaborating with people you don’t agree with or like or trust . Design/methodology/approach Based on his experience as a collaboration facilitator in national and regional conflicts and stalemates, the author explains how to achieve success through what he terms “stretch collaboration.” Findings Stretch collaborations requires participants to take three unconventional approaches. Practical implications Unconventional “stretch collaboration” abandons the assumption of control. It gives up unrealistic fantasies of harmony, certainty, and compliance, and instead embraces messy realities of discord, trial and error and co-creation.” Originality/value Managers and leaders increasing must collaborate with stakeholders who have opposing interests. This stretch collaboration process offers a way to make progress even in volatile, hostile, high-risk situations.

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.

Physical design and synthesis are two key processes of quantum circuit design methodology. The physical design process itself decomposes into scheduling, mapping, routing, and placement. In this paper, a mathematical model is proposed for mapping, routing, and scheduling in ion-trap technology in order to minimize latency of the circuit. The proposed model which is a mixed integer linear programming (MILP) model gives the optimal locations for gates and the best sequence of operations in terms of latency. Experimental results show that our scheme outperforms the other schemes for the attempted benchmarks.
