In order to respond to the challenge of sustainable development, organizations need to manage the social, environmental and economic impacts of their activities. Existing approaches to manage organizational sustainability either are limited by a narrow perspective or lack concepts and tools to integrate sustainability considerations into day-to-day business. We address this issue by proposing a tactical management dashboard based on Organizational Life Cycle Assessment (O-LCA), an authoritative and comprehensive methodology for organizational sustainability analysis.We have developed a concept for a tactical sustainability management dashboard based on O-LCA guidelines and best-practices for dashboard design that allows managers (who may not be LCA experts) to explore, analyze and interpret O-LCA study results. The concept was implemented in an early software prototype and evaluated regarding its usability. Our concept and prototype show the viability and utility of a management tool based on O-LCA.
