Mission for Siemens: build a partner ecosystem (universities, trade shows, think tanks) and amplify the impact of thought leadership on the industry of the future. Trois Actes ran a year-long intermediation mission, using “Ingenuity for life” as an alignment filter. The program was structured in three steps: framing (objectives, audiences, risks, criteria), mapping (47 stakeholders, 18 qualified approaches), then signature and activation (negotiation, contracting, activation kit and follow-up). Each partnership was designed to remain actionable for internal teams. At the end of the mission, three structuring partnerships were finalized, with a consolidation roadmap.
