1. Menold, Jessica D. Prototype for X (PFX): A Prototyping Framework to Support Product Design.

Degree: 2017, Penn State University

Of the estimated 140 billion US dollars spent in new product development by large companies each year, around 40% is wasted on failed products. The largest sunk cost in new product development occurs during prototyping activities. We know prototyping activities are critical to the design process as they translate often fuzzy ideas into physical artefacts, support communication, enhance design development, and aid in decision-making. Engineering design research has failed to provide designers and engineers—practitioners as well as educators—with formal methods or approaches for prototyping to help reduce these losses and increase the likelihood of product success. Instead, designers and engineers must rely on experience, tacit knowledge, and individual judgment to navigate prototyping activities, often resulting in the inefficient use of resources and time. An extensive literature review of prototyping research and a study of novice designers’ perceptions of prototyping are used in this work to develop and validate a set of specifications for a holistic and structured prototyping framework. A novel framework to help structure prototyping, Prototype for X (PFX), is proposed as an alternative to traditional prototyping approaches in engineering design. The PFX framework is composed of three main phases: (1) Frame, (2) Build, and (3) Test. The phases of PFX help designers optimize resources to build prototypes that test core assumptions and inform the design and development new products. Similar to the “illities” in Design for X, PFX uses lenses to structure and scaffold the prototyping process to make improvements in specific areas. In order to validate the PFX framework, in this work we study the effects of three lenses, namely, Prototype for Desirability, Prototype for Feasibility, and Prototype for Viability. These lenses are based on Human-Centered Design and Design Thinking frameworks for innovation and innovative products. In order to evaluate the effectiveness of PFX at improving technical quality, manufacturability, and user satisfaction of end designs, we assess functional prototypes developed in a junior-level mechanical engineering design course. Results from a between-subjects analysis indicate that using PFX can help increase the desirability, feasibility, and viability of functional prototypes when those lenses are applied; specifically, student teams introduced to PFX produced prototypes that outperformed those from control teams with no formal prototyping methods on user satisfaction, perceived value, and manufacturability metrics. This study confirms the impact that structured prototyping methods like PFX can have on the prototyping process and final designs. In order to understand the effect of structured and holistic prototyping models on designers themselves, we evaluate the impact PFX has on designers’ prototyping awareness. The prototyping literature has typically evaluated the few prototyping methods, tools, and frameworks using design-based metrics, such as binary evaluations of… Advisors/Committee Members: Kathryn Jablokow, Dissertation Advisor/Co-Advisor, Timothy Simpson, Committee Chair/Co-Chair, Scarlett Miller, Committee Member, Meg Small, Committee Member, Aaron Knochel, Outside Member, Timothy Simpson, Dissertation Advisor/Co-Advisor, Kathryn Jablokow, Committee Chair/Co-Chair.
