“…It is widely acknowledged that formal methods can contribute to improvement of the development processes as well as of quality of the products (see e.g., Savino and Mazza, 2014;Opiyo, 2003). To this end, process models serve, among other things, as means to support systematic elicitation and specification of requirements and to assure consistent monitoring of fulfilment of requirements as the design process progresses (see e.g., Opiyo et al, 2002;Opiyo et al, 2009).…”

“…Some literature suggests that the application of formal methods, especially at the analysis, requirements specification, and at the design phase improves quality through reduced defects in the final products (see e.g., Langari et al, 2005;Opiyo et al, 2002). Since structural design is part of the design process, it is expected that the application of the observed LRL structural design scheme would also contribute to further quality improvements through reduction of errors and omissions in the in-process deliverables.…”

“…The importance of using well-defined and structured design process models and the implications of using them, as far as quality and the acceptance of the designed product is concerned, is widely recognised. Structured design process models evade propagation of errors and some literature suggests that they also increase of quality (see e.g., Sánchez-González et al, 2013;Langari et al, 2005;Opiyo et al, 2002). It is broadly understood that most decisions that influence quality and cost of the designed product are made during design.…”

This paper presents the findings of a study conducted to explore how structural design unfolds in industrial design engineering processes. The study focused specifically on structural design of engineering consumer products with physical constructions. The investigation conducted included questionnaire surveys, interviews, and observations. A total of 358 subjects participated in two rounds of the investigation. The study uncovered how structural design in the context of industrial design engineering progresses in practical settings and provided clues on how a formal structural design process model should be like. One of the main observations was that the subjects chose and strictly followed and adhered to their own preferred structured order of execution of structural design activities. Another cardinal observation was that, unlike analysis and concepts development activities, the structural design activities of materials selection, engineering analysis, and process selection were executed recursively and oftentimes concurrently by most of the subjects. Based on these observations and upon an analysis of the information gathered, a linearrecursive-linear (LRL) scheme for tracking, managing, and coordinating the execution of structural design activities has been formulated. Separate studies are, however, needed to investigate the validity, efficacy, and the applicability of this scheme.

“…It is also meant to encourage and to facilitate early discovery of faults. To this end, abstract prototyping serves as a prototyping and review technique for the in-process deliverables of the fuzzy-front end stage of the development process-see, e.g., [24][25][26][27][28]. That is, theories/concepts or engineering principles, methods or functional units, algorithms or architectural layouts, and pilot prototypes are treated as reviewable or testable implementations.…”

An Approach to Represent and Communicate Product or System Design Ideas at the Fuzzy-Front End of the Design Process

Abstract:The primary challenge underscored and dealt with was how to represent the product's or system's use environment and processes and to communicate ideas and envisaged use contexts effectively at the fuzzy-front early stages of the design process. The work focused specifically on complex products or systems with physical, software and/or cyber components, and the question was how to represent, e.g., the operations of the product or system and the interactions between the user and the product or system betimes in the period between when an opportunity for a new product or system is first considered, and when the idea is judged to be ready to enter formal development. Several approaches are currently being used to express and to communicate ideas at the conceptualization, embodiment, and detail design stages of the design process, but none of them address the challenge described above. We therefore adapted and extended the abstract prototyping concept to allow for total representation of ideas, as well as of use environments and processes early on. Extended abstract prototyping (Ext-AP) entails using combinations of low and high-fidelity prototyping techniques to create cognitive virtual representations, which represent and help designers to express ideas and use contexts-namely, what complex product or system would be like, and how its users would interact with it. Real-world product development case studies have been used to demonstrate how the Ext-AP technique can be put into practice. One of the main observations from the application case studies is that the Ext-AP technique enabled the subjects to express ideas and use contexts more effectively early on. In addition, the extended abstract prototypes (Ext-APs) offered a low cost, yet effective solution for expressing ideas, representing concepts and using contexts, and allowed the subjects to think divergently, make associations, easily and quickly construct, combine, and evaluate alternatives, and work together on multiple ideas simultaneously.

“…Although the literature from training and development, product development and computer software tends to use the terms 'pilot-test ' and 'beta-test' interchangeably (for example, Chernick 1992;Wurangian 1993;Howe and Pearlstein 1995;Rosenkrans 2001;Opiyo, Horvath, and Vergeest 2002), there are subtle differences between the two activities. Dolan and Matthews (1993) pointed to one important distinction: product design should be frozen prior to the beta-testing phase.…”
