Summarize Bowes ox sees performance measurement as a barrier for functional integration because different functional areas within an organization may have different priorities and goals. When performance is measured based on functional metrics alone, it can create silos within the organization, leading to a lack of cooperation and coordination between departments. This can hinder the integration of different functions toward a common goal or objective. Bowes ox believes that a holistic approach to performance measurement that considers cross-functional collaboration and overall organizational goals is essential for achieving successful functional integration.
