“…Frequent interactions with the stakeholders enable rapidity during the requirements definition and analysis process because SE can obtain early feedback from the stakeholder and manage new, unidentified or changing requirements. Continuous stakeholder feedback is an essential element of RSE (De Beer et al, 2009). When using a linear-sequential approach, the project is at risk of taking too long to complete and not meeting the stakeholder needs at the time of delivery, because the original requirements or business needs have fundamentally changed (Maner, 1997).…”

Systems Engineering (SE) has been traditionally viewed as an extremely rigorous approach for having resource intensive processes often perceived to involve bureaucratic decision making; therefore, deemed to be affordable only by large companies and government institutions. However, in recent years, the commercial industry is trying to leverage the benefits of SE by selecting the relevant aspects that apply to them and customising SE to a leaner and compressed version. This paper explores the suitability and the feasibility of rapid approaches and techniques to the existing SE processes. More specifically, this paper describes 22 techniques of rapid systems engineering (RSE) during the design and implementation processes, relevant to those processes and lessons learned. These techniques are applied to the 14 SE processes as illustrated by the SE standard-ISO 15288. An exploratory survey was developed by the authors based on the SE process activities as per ISO 15288 to evaluate application utilising a rapid approach in current projects from various industries. This paper provides conclusions to applying rapid techniques to the SE processes based on existing literature and the experiences of the projects surveyed. It concludes with a discussion of potential research projects for the evaluation of RSE.

“…If this evaluation can be undertaken early in the product development process (essentially, as soon as a CAD model is available), then customer feedback can be used to help drive the remaining design iterations of the product. This has previously been termed 'Customer Involvement through Functional Prototypes' (CIFP), and has been demonstrated to be effective with consumer products [1], medical implants [2], and professional use products [3].…”

This paper draws on previous work by the authors that aimed to use functional prototypes, produced using additive manufacturing (AM), as a means to draw customer input and preferences into the development of new products. This technique is referred to as Customer Interaction through Functional Prototypes (CIFP). The CIFP philosophy has been proven in both consumer and medical products. In recent years, the authors have developed further concepts of AM-enabled enhanced consumer involvement within their respective research teams. This paper discusses the extended use of CIFP to develop innovative new product concepts in the Vaal University of Technology, to support grantholders of the Industrial Development's Corporation (IDC) Support Programme for Industrial Innovation (SPII) and the Technology and Innovation Agency (TIA). The paper goes on to discuss a novel method of consumer interaction developed at Loughborough University, referred to as a Computer-aided Consumer Design (CaCODE). This technique allows nondesigners to take an existing product design (e.g., a pen) and modify its shape in real time, in order to create a customised version of the product that meets their needs. The modification is limited within pre-defined parameters to make sure that any final design is functional and can be produced using AM. OPSOMMINGHierdie artikel is geskoei op die gebruik van toevoegingsvervaardiging om kliënt insette en voorkeure in te sluit by die ontwikkeling van nuwe produkte. Die tegniek word die Kliënt Interaksie deur Funksionele Prototipes (CIFP) genoem. Die CIFP filosofie is al bewys in verbruikers-en mediese produkte. Verdere konsepte vir die gebruik van toevoegingsvervaardiging om kliënt betrokkenheid te bevorder is die die outeurs ontwikkel. Hierdie artikel bespreek die uitgebreide gebruik van CIFP om innoverende nuwe produkte te ontwikkel by die Vaal Universiteit van Tegnologie ter ondersteuning van navorsers wat steun van die Industriële Ontwikellings Korporasie (IDC) en die Tegnologie en Innovasie Agentskap (TIA) ontvang. Die artikel bespreek verder 'n nuwe metode vir verbruiker interaksie soos ontwikkel by Loughborough Universiteit, bekend as Rekenaar gesteunde Verbruiker Ontwerp (CaCode). Dié tegniek laat ontwerp-leke toe om 'n bestaande produk aan te pas om aan hulle vereistes te voldoen. Hierdie aanpassing is beperk binne voorafbepaalde parameters om te verseker dat die finale ontwerp funksioneel en vervaardigbaar is.

“…Prototyping is a combination of methods that allows physical or visual form to be given to an idea (Kelley & Littman, 2006; Schrage, 1999) and plays an essential role in the product development process, enabling designers to specify design problems, meet user needs and engineering requirements, and verify design solutions (De Beer, Campbell, Truscott, Barnard, & Booysen, 2009; Moe, Jensen, & Wood, 2004; Viswanathan & Linsey, 2009; Yang & Epstein, 2005). Designers tend to think of prototypes as three-dimensional models, but nonphysical models, including 2D sketches and 3D CAD models, as well as existing products or artifacts, can also serve as prototypes (Hamon & Green, 2014; Ullman, Wood, & Craig, 1990; Wang, 2003).…”

“…Design experts leverage their accumulated knowledge and experience and select the most appropriate approaches to prototyping to answer specific design questions (Houde & Hill, 1997), and expert designers rely heavily on prototypes to quickly test an idea or generate new ones. By doing so, they improve a concept and advance the design through the individual project phases (De Beer et al, 2009; Dow et al, 2010; Knapp, Zeratsky, & Kowitz, 2016). …”

Novice designers' use of prototypes in engineering design

et al. 2017

Prototypes are essential tools in product design processes, but are often underutilized by novice designers. To help novice designers use prototypes more effectively, we must first determine how they currently use prototypes. In this paper, we describe how novice designers conceptualized prototypes and reported using them throughout a design project, and compare reported prototyping use to prototyping best practices. We found that some of the reported prototyping practices by novice designers, such as using inexpensive prototypes early and using prototypes to define user requirements, occurred infrequently and lacked intentionality. Participants’ initial descriptions of prototypes were less sophisticated than how they later described using them and only upon prompted reflection did participants recognize more specific benefits of using prototypes.
