During a daily standup in a hybrid project, two senior developers begin arguing about the architectural approach for a critical user story. The argument escalates, becoming personal and disrupting the meeting. The team looks uncomfortable. What should the project manager do FIRST?

Allow the debate to continue as it demonstrates passion and technical engagement, which is healthy for agile teams.

Intervene to pause the discussion, reminding the team of the standup's purpose, and schedule a separate breakout session for the two developers.

End the standup immediately and report the behavioral issue to the functional managers of the developers.

Decide on the architectural approach yourself to resolve the impasse and allow the team to move forward.
