Ideally, integration preparations should begin even before the transaction is finalized, in parallel with due diligence. However, our program can be deployed effectively from the official announcement and up to 2-3 months after the merger. This period represents a crucial window of opportunity when teams are particularly receptive to change and new working dynamics begin to crystallize. Our approach adapts to your specific timetable, while preserving its fundamental principles of efficiency.

Our methodology begins with an in-depth cultural diagnosis that precisely maps the values, practices and behaviors of each organization. Rather than imposing a dominant culture, we facilitate the emergence of an "integrated culture" that preserves the best of both worlds. Our "Cultural Bridge" workshops enable teams to identify complementary strengths and co-create a shared cultural vision. This participative approach transforms differences into opportunities for mutual enrichment, rather than sources of friction.

Together with you, we draw up a balanced scorecard covering four essential dimensions: operational performance (realization of synergies), human commitment (talent retention, satisfaction), cultural integration (adoption of new values) and external perception (customers, partners). Each dimension is measured by specific KPIs and monitored in real time via our digital platform. Regular checkpoints enable us to adjust the approach and celebrate progressive successes, thus creating a positive dynamic.

Uncertainty is the main cause of stress and disengagement during a merger. Our program incorporates a transparent, sequenced communication strategy that reduces this uncertainty. We also deploy collaborative workshops that actively involve teams in building the shared future, giving them a sense of control and ownership. Our "Quick Wins Sessions" enable visible improvements to be identified and implemented rapidly, demonstrating the benefits of the merger in concrete terms and reinforcing confidence in the new organization.
