The project manager should conduct a consensus-building session to decide how to approach the next set of work, as this is a collaborative decision-making technique that involves the participation of all team members and stakeholders. The project manager should facilitate the discussion, clarify the objectives, identify the options, evaluate the pros and cons, and reach a mutually acceptable agreement. This will help to resolve the conflict, align the expectations, and ensure the commitment of the team and the stakeholders. The other options are not the first actions that the project manager should take, as they may either delay the decision, bypass the team's input, or ignore the conflict. References:
