Translating User Sensations into Design Specifications with QFD

Quality Function Deployment (QFD) can systematically translate subjective user sensations and usability requirements into concrete physical design attributes.

Human Factors and Ergonomics in Manufacturing & Service Industries · 2009

Key Findings

01A QFD-based model can effectively link user sensation and usability factors to physical design attributes.
02Key physical design factors influencing user sensation were identified as Label Icon, Rack Size, Shape of Knob, and LCD size for dishwashers.
03Design guidelines can be derived from the prioritized physical design factors.

Application

Design takeaway

How to apply

When designing a new product or redesigning an existing one, use QFD to create a 'House of Quality' matrix. Input user needs and sensations as 'customer requirements' and translate them into technical requirements or physical design attributes.

Project actions

01When gathering user feedback, focus on both functional usability and emotional responses (sensations).
02Consider using QFD as a structured way to organize and prioritize design decisions based on user input.

Method & Evidence

AimTo develop a framework for evaluating product usability by systematically linking customer sensations and usability factors to physical design attributes using Quality Function Deployment (QFD).

MethodFramework Development and Case Study

ProcedureThe research involved analyzing customer sensations and usability through tests, creating evaluation factors from these results, and involving experts to select physical design factors. These elements were then integrated into a QFD-based evaluation model to identify and prioritize physical design attributes influencing user sensation, leading to the derivation of design guidelines.

ContextProduct design, specifically focusing on dishwashers, with implications for consumer electronics and appliances.

Variables

IV["Physical design factors (e.g., Label Icon, Rack Size, Knob Shape, LCD size)","User sensations and usability evaluations"]

DV["Degree of influence of physical design factors on user sensation","Derived design guidelines"]

CV["Product type (dishwashers)","Expert panel composition","Testing environment"]

Strengths & Limitations

Strengths

+Systematic approach to linking user needs with design features.
+Inclusion of expert input alongside user testing.

Limitations

The complexity of QFD can be challenging to implement fully in a limited timeframe. Generalizing findings from one product type to another requires careful consideration.

Reliability & validity

The reliability of user sensation data can be improved through repeated testing and averaging responses. Validity is enhanced by involving experts and using a structured framework like QFD to ensure that the design attributes truly reflect the user feedback.

Think critically

How might the 'sensation' aspect of user feedback be quantified or objectively measured to reduce subjectivity in the QFD process?

Design Principles

"User sensations and usability requirements should be explicitly mapped to physical design attributes using structured methodologies like QFD to ensure user-centric product development."

This approach bridges the gap between abstract user needs and tangible product features, ensuring that design decisions are directly informed by user experience. It provides a structured method for prioritizing design elements based on their impact on user satisfaction and product performance.

What This Means for Your Design

This research shows how designers can use a tool called QFD to figure out exactly which parts of a product's design (like the size of a button or the look of a label) will make users feel good about it and find it easy to use, based on what users say they like and how they use it.
