GRAFT was developed rapidly by Arup’s Product Design
team, working closely with the Zumtobel development team in
Austria. Our CAD/CAM tools, global network of specialists and
manufacturing knowledge brought the product to market in just eleven months.
“Working together with Arup gave us the feeling that we doing more than just fulfilling
the requirements of a design brief. The multi-disciplinary team enriched the
development process with application knowledge, innovative ideas and active
feedback from a genuinely global network. The end result is a leading product that
meets both the Arup and Zumtobel standards for delivering genuine customer
benefits through innovation and application-led design excellence.”
Adam Burton, Global Application & Product Management, Zumtobel GmbH
We drew on Arup and Zumtobel experience to
develop the product and bring GRAFT to market,
offering a range of product design, idea generation,
global product evaluation and development
techniques.
This process encouraged innovative thinking, better
product performance, creativity and collaboration to
shape a better product.
