World Usability Day 2009 is approaching design from Cradle to Cradle. Coming from a user-centric perspective and looking beyond form and function, we are exploring the impact design has on our World. The ‘Cradle to Cradle’ approach is to start the design with the premise of using materials that can fully enter a new life cycle by either going back to nature or going back into the design process as a new product. This holistic approach to sustainable design shows how usability can apply to all of what we do and build.Designing for a Sustainable World focuses on how our products and services impact our world. We look at all products and services, whether they are buildings, roads, consumer products, business, services or healthcare systems; throughout their life cycle. The impact focuses on - our environment, energy, water, soil, and more. Have the materials and processes that have been used been recycled and are they re-usable? Are they user and environmentally friendly? These are questions we all must consider as we design, purchase, use and dispose of products each and every day.
