Usefulness Simulation of Design Concepts

Abstract

Usefulness, from the utilitarianism perspective, is the ability of a product or service to improve the well-being of humans and to minimize their suffering in different situations. In the case of the widespread issue of falls among the elderly, designing an adapted solution to is not an obvious task. The latter requires quantifying various usage scenarios. The usage scenarios, or segments, associated with elderly falls must be investigated to ensure that newly designed products and services are likely to bring essential health, social, and economic values. Optimizing a design solution by considering the coverage of such usage segments extends the classical methods of design for market approaches. Starting from a disparate literature on elderly falls’ issue, we have first built a usage scenarios space. Next, the usefulness and the coverage ability of three design solutions are evaluated over a tessellation of usage segments. In addition, the developed usage simulator is used to assess the potential of non or poorly covered usage segments to deliver insightful information in order to truly be a need seeker in the front-end of innovation.

Usage-driven problem design for radical innovation in healthcare

“…They can be written stories or, better, short movies or storyboards. They are a communication tool.An additional dimension is how existing solutions apply to situations and how they solve problems 38. For example, in dental hygiene, ‘dental flush’ and ‘mouthwash’ do not address the same issues.…”

“…Usages: A usage is a situation happening when a type of user encounters a type of environment 38. It describes the actual way people act in given situations and which pains they experience.…”

Mining customer product reviews for product development: A summarization process

“…It comprises all the factors characterizing an application and the environment in which a product is used (Green, Tan, Linsey, Seepersad, & Wood, 2005). Knowing usage conditions is important in design evaluation, usage scenario simulation, and user pain identification, because usage condition influences customer behavior through product performance, choice, and customer preference (Bekhradi, Yannou, Farel, Zimmer, & Chandra, 2015;Yannou, Cluzel, & Farel, 2016 (2012) emphasized that usage condition covers all aspects related to the use of a product but excludes customer profile and product attributes.…”

The UNPC innovativeness set of indicators for idea or project selection and maturation in healthcare

“…Indeed, this is the principle of the popular blue ocean strategy developed by Kim and Mauborgne (2005). Recently, the authors proposed a method to compute usefulness indicators of design concepts (Bekhradi, Yannou, Farel, Jena, and Zimmer, 2014;Bekhradi, Yannou, Farel, Zimmer, and Chandra, 2015) by usage segmentation techniques, measuring the degree of dominance of a product or an idea by summation over all usage segments. A first approach considers the effectiveness of the product/idea weighted by the size of the usage segment.…”

“…This is the notion of usage coverage indicators (Yannou, Yvars, Hoyle, and Chen, 2013). The second approach compares the usefulness dominance of the product/idea under study to existing offers (Bekhradi et al, 2015).…”
