How can SAP Signavio enhance cross-departmental collaboration?

SAP Signavio enhances cross-departmental collaboration primarily by standardizing and sharing process models across different business units. This approach allows various departments to utilize a common understanding of processes, which fosters alignment and coherence in operations. When departments have access to standardized process models, they can more effectively coordinate their efforts, communicate shared goals, and implement improvements collaboratively. This transparency helps to break down silos, ensuring that all units are working from the same foundational knowledge and objectives.

The other choices do not contribute to enhancing collaboration. Restricting access to process models limits communication and understanding between departments, while isolating departments creates barriers that hinder teamwork and shared initiatives. Lastly, automating interdepartmental communication does not fully address the need for a unified understanding of processes, which is crucial for effective collaboration.
