Industrial companies increasingly want to eco-innovate in their project but have to deal with strict constraints in time and resources. Thus, a time-efficient eco-innovation workshop process for complex system industries is proposed. From the selection of a relevant multidisciplinary working group (before the workshop) to the follow-up of environmental projects (after the workshop) through eco-ideation and eco-selection (during the workshop), all stages are considered. The proposed workshop lasts in all three hours and is experienced on an industrial complex system at Liebherr.
