How can companies ensure that their efforts to break down barriers between departments and promote cross-functional collaboration are sustainable in the long term, rather than just a temporary fix?

Companies can ensure sustainable cross-functional collaboration by creating a culture that values teamwork and open communication. They should invest in training programs that promote cross-functional understanding and encourage employees to work together towards common goals. It is important to establish clear processes and structures that support collaboration, and to regularly review and adjust these strategies to ensure they remain effective in the long term. Additionally, recognizing and rewarding collaborative efforts can help reinforce a culture of teamwork and ensure that cross-functional collaboration becomes ingrained in the company's culture.
