Companies can ensure the sustainability of their cross-functional innovation efforts by fostering a culture of collaboration and knowledge sharing among different departments. This can be achieved by establishing clear communication channels and processes that facilitate the integration of customer experience knowledge into decision-making. Leadership plays a crucial role in this process by setting the tone, providing resources and support, and championing a customer-centric mindset throughout the organization.
