Conflict resolution is a critical skill in project management. The PMBOK Guide suggests that conflicts should be addressed using a problem-solving approach, which involves direct confrontation and working collaboratively to identify a solution that satisfies all parties1. This aligns with the Professional in Business Analysis (PMI-PBA) guidelines, which recommend discussion and negotiation among conflicting parties to reach an agreeable solution3. Ignoring the problem or delaying action (options A and C) can lead to a decrease in team morale and productivity, while escalating the issue to HR (option D) should be a last resort after other methods have failed.
