Design process components and perceived product quality
Historically one of the priorities of design is to create a progression in the form of everyday experience (Beirne, 2011)
But…UsabilityUser experienceUser centred design Human centred designHuman FactorsErgonomicsParticipatory design…
bad user experience ?!
Exponential growth & increasing complexityof products

What happens in a design process?
• State of the art
• Design shaping methods
• Ergonomic & functional study
• Users involvement
• Design research tools

WHAT AFFECTS THE PERCEIVED PRODUCT QUALITY?AND WHAT CAN LEAD TO (ACCEPTANCE OF) INNOVATION
Research• Innovation is technology driven (Norman
& Verganti, 2014)• Innovation is created by creating new
meaning (Verganiti 2014)
• UX becomes important when people become more familiar (Norman & Verganti 2014)
Professionals (seat design)
• Importance of involving all stake holders including management an OEM
Effect of the design process components on the perceived product quality
Re-designPositive effect on the PPQ:• ‘function, risk and mistake analysis of
the designed product’
New designPositive effect on the PPQ:• ‘involving users by asking feedback
on 2D concepts’ • ‘applying design research tools in the
design process’
New designNegative effect on the PPQ:• ‘Consulting ergonomic guidelines’
Design for people with disabilities or special needs
Positive effect on the PPQ:• ‘design shaping by making (working)
models’• ‘functional, risk and mistake analysis’
(of the designed product)’ • ‘user feedback on (working) concepts
and models’
What about the other components?
No correlations because• Always applied• To moderate to measure• Interferences between components • Just no correlation
IMPORTANT DESIGN PROCESS COMPONENTS FOR CREATING COMFORT
CDP important for comfort (in seat design , based on professionals)
• prototyping• function, risk and mistake analysis
(of the designed product)• designing by making working models • focus groups • questioning users• Involving stakeholders
DESIGN VERSUS REAL WORLD
Can designers estimate the users perception of product quality?
DesignersVS users• Products for general target group:Strong correlation (= 0.743, p ≤ 0,000) between product assessment of designer and users
Designers VS usersProducts for people with specific needs or disabilities :no correlation (= 0.47, p = 0,066) between product assessment of designer and users
HOW TO INCREASE PERCEIVED PRODUCT QUALITY
Increasing perceived product quality by:
• Applying design process components which can have a positive effect on the perceived product quality
• Differentiate the design process in function of the design problem
Increasing perceived product quality by:
• Involving users in the design process and assessment
• Involve other stakeholders
