Abstract
The overall goal of the novel Functionality, Usability, Look-and-Feel, and Evaluation (FULE) user-centered methodology for product design proposed in this paper is to develop usable and aesthetic products. Comprising several product design methods, this novel methodology we devised focuses on the product designer’s role and responsibility. Following the first three formative assessment phases that define the product’s functionality, usability, and look-and-feel, the summative evaluation phase not only assesses the product, but also provide guidelines to its implementation, marketing, and support. A case study devoted to the design of an autonomous medical device illustrates how the FULE methodology can provide the designer with tools to better select among design alternatives and contribute to reducing bias and subjective decisions.
Highlights
Illustrated in the CaseWhether involving a brand-new product or improving and updating an existing one to evolving and changing demands, the product design process is need-driven
This paper presents an overview of the FULE methodology phases, followed by a case study that illustrates implementation of the FULE methodology
The FULE methodology is focused on the product design of professional medical devices intended for utilization by professional medical teams in professional medical environments
Summary
Methodology—Illustrated in the CaseWhether involving a brand-new product or improving and updating an existing one to evolving and changing demands, the product design process is need-driven. Some of the methodologies focus on a narrow part of the process, aiming to generate innovative solutions and produce a great number of ideas and concepts [3,4] These include methods for exchanging knowledge in multidisciplinary product development teams [5], solving ergonomic design and usability issues [6], examining the aesthetic aspects of the product [7], or focusing on the design of particular objects and demands such as soft wearable devices, sports equipment, or emergency ventilators [8,9,10]. We developed and formulated the Functionality, Usability, Look-andFeel, and Evaluation (FULE) methodology based on ten years of experience in developing various medical devices and participating in many design processes This method evolved of an Autonomous Medical Device. Nurses’ high workload in ICUs leads to major worker stress and harms patient safety [13]
