The Okala Ecodesign Strategy Wheel is a modification of the wheel developed by Brezet and van Hemel. The wheel clusters strategies according to the stages of the lifecycle of the product. It serves as a powerful brainstorming tool to explore areas of product development or improvement that have not yet been considered. Ecodesign requires as much thoughtful design thinking as any other design activity. This means recognizing when an ecodesign strategy is or is not working in a project or system. The ecological effectiveness of the strategy can be best gauged by a Life Cycle Assessment (LCA) to measure the product system impacts.
