A project will deploy a new solution to branches in different countries. Each country's deployment team encounters similar issues but resolves them independently. What should the project manager do to improve collaboration among the teams?

Organizing regular meetings with all deployment teams directly addresses the problem of independent issue resolution by creating a forum for sharing. This fosters collaboration, allows teams to learn from each other's experiences, and promotes consistent problem-solving across different countries, ultimately improving efficiency and effectiveness. Asking the sponsor to appoint new managers is an extreme and likely unnecessary measure that doesn't address the communication gap. Proposing deployment delays is counterproductive and would negatively impact the project schedule. Asking for detailed schedules and action plans might provide information but doesn't inherently facilitate the sharing of solutions to common problems, which is the core issue.
