You are managing a project team and have noticed that one of your team members, John, has been consistently missing deadlines and producing subpar work. What is the most appropriate course of action to address this situation?
Ignore the issue and hope that John's performance improves on its own
Schedule a one-on-one meeting with John to discuss his performance and develop an improvement plan
Discuss John's performance issues with the entire team during a team meeting
Immediately remove John from the project team and find a replacement
