Applying Life-cycle thinking
• Life cycle costing and life cycle assessment allow the
effects of a material or product innovation to be
considered in advance
• Can indicate where innovations have most impact
• Can help avoid costly mistakes
• Close liaison with supplier/manufacturer is needed to
obtain robust data
