How should a Scrum Master resolve local optimizations hurting cross-team integration?

Tests whether you recognize that local optimization is an organizational impediment the Scrum Master must resolve through global optimization rather than internal team tweaks. A strong answer covers four moves: first, make the friction visible with data; second, convene decision-makers to align on company goals; third, broker a sustainable cross-team workflow; and fourth, shield the team during the change. Red flag: ignoring the issue, blaming other teams, or escalating to management without first building a collaborative case.
