In distributed or virtual teams, poor communication and lack of effective collaboration tools can severely hinder progress. Before escalating to the sponsor or modifying the rollout strategy, the project manager should first assess the team's ability to collaborate and identify if technical or communication barriers are the root cause.

Option A is premature without addressing the root cause.

Option B can backfire and does not solve collaboration issues.

Option D might be a long-term strategy but is not the first corrective step.
