For this purpose, requirements regarding the design task, development process, participants, equipment, and data collection for a Live- Lab are derived based on a literature review and expert interviews. Subsequently, a Live-Lab is developed and presented in which the test subjects develop and manufacture a gas grill over six months. Based on the concept of the Live-Lab, which was implemented and carried out in three years, the validation of three different approaches for methodological design support is described. These approaches address (1) engineering generations and variation types, (2) sheet metal design concerning sustainability, and (3) decision heuristics in agile development.en2212-827120234146Elsevierhttps://creativecommons.org/licenses/by-nd/4.0/design supportLive-LabPGE – Product Generation Engineeringsheet metal developmentvalidation environmentEngineeringConference Paper10.15480/882.837710.1016/j.procir.2023.03.08210.15480/882.8377Conference Paper
