When faced with internal team conflicts, especially between a team lead and an experienced engineer, it is important to address the issue collectively. Organizing a meeting with the project team allows for open communication and collaborative problem-solving. This aligns with the PMBOKGuide's principles of conflict resolution, which include promoting a team environment where issues can be discussed and resolved in a manner that respects all parties' perspectives1. It also adheres to the Professional in Business Analysis (PMI-PBA) guidelines, which emphasize the importance of addressing conflicts directly and seeking a resolution that supports project delivery2.
