Development of a usability evaluation framework with quality function deployment: From customer sensibility to product design

Abstract

The aim of this research was to develop a usability evaluation model based on customer sensation using quality function deployment (QFD), which evaluates the relationship between consumer sensation and usability among the physical design factors of dishwashers. Four aspects of the evaluation model were analyzed with QFD: overall sensation factors, detail sensation factors, usability evaluation factors, and physical design factors of products in 3 sequential processes. The sensation evaluation factors and the usability evaluation factors were created from the results of the sensation and usability tests. Moreover, experts and manufacturers were involved in selecting the physical design factors. With the evaluation model using these 4 aspects, physical design factors influencing user sensation were generated. These factors were Label Icon, Rack Size, Shape of Knob, and LCD size. In addition, the degree of influences was tested and design guidelines derived from the final physical design factors were generated. C 2009 Wiley Periodicals, Inc.

A model-based framework for classifying and diagnosing usability problems

“…Usability factors can be categorized into two groups: objective and subjective. Objective usability factors are concerned with the assessment of how well users perform their tasks, whereas subjective usability factors attempt to evaluate how users actually feel the usability of a system (Bevan 1999;Jin et al 2009). …”

A Weighted QFD-Based Usability Evaluation Method for Elderly in Smart Cars

“…According to the literature reviews on current practices of usability evaluation method development (Chan & Wu, 2002;Demirbilek & Demirkan, 2004;Jin, et al, 2009;Lager, 2005;Song & Lee, 2008), many studies utilized quality function deployment (QFD) in the usability evaluation to determine the priorities of demands, or to analyze the relationships between development requirements. QFD is a user-centered product design tool that collects the user needs applicable to each step of product planning, design, engineering, and manufacturing and then easily translates them to a form that can be applied to functional redesign.…”

“…The authors noted that there is some difficulty in using the result in standardized usability principle evaluation. Jin et al (2009) used QFD to combine and evaluate usability and sensibility. Also, they pointed out that they produced more quantitative outcomes through this evaluation, using QFD methodology to eliminate the expert's and the researcher's subjective evaluation.…”

Integrating Refined Kano Model, Quality Function Deployment, and Grey Relational Analysis to Improve Service Quality of Nursing Homes

“…QFD is a cross‐functional tool (Wasserman, 1993) that aims to transform customer requirements into standards and services provided by businesses and has become the standard for product establishment and service design (Jin et al, 2009; Lowe, Ridgway, & Atkinson, 2000). It systematically deploys the design to each part or service item as well as to the relationship of elements between manufacturing engineering and service engineering so that products and services will meet the expectations and requirements of customers (Bahn et al, 2009; Chen & Weng, 2006).…”

“…It systematically deploys the design to each part or service item as well as to the relationship of elements between manufacturing engineering and service engineering so that products and services will meet the expectations and requirements of customers (Bahn et al, 2009; Chen & Weng, 2006). In conclusion, QFD is a systematic structure that integrates the voice of customers into the process of product development (Jin et al, 2009). …”
