Abstract: This article examines the critical challenges that hinder cross-functional collaboration in modern organizations despite its essential role in driving innovation and problem-solving. The authors identify four primary barriers: lack of shared understanding between departments regarding priorities and working methods; organizational silos that foster an "us versus them" mentality; insufficient leadership commitment to breaking down barriers; and individual mindsets that view other functions as competitors rather than partners. The research then proposes organizational design solutions to overcome these obstacles, including establishing shared goals across departments, blending functional expertise within teams, fostering communities of practice, leadership modeling of collaborative behaviors, utilizing skilled project managers, and implementing cross-training programs. The authors conclude that intentional realignment of organizational structures toward supporting cooperative behaviors can create environments where multi-disciplinary problem-solving flourishes, ultimately benefiting both internal stakeholders and end customers.
