A project manager notices that a previously high-performing team member has been struggling with quality and missing deadlines since being promoted to a technical lead role. The team member now has mentoring responsibilities for junior developers in addition to their individual contributions, and appears overwhelmed by the expanded role. Which TWO actions should the project manager take to support this team member's performance?

Reduce the team member's individual workload to focus exclusively on leadership responsibilities

Document the performance issues and establish a formal performance improvement plan

Provide coaching on leadership skills, time management, and balancing individual and mentoring responsibilities

Reassign the mentoring responsibilities to another senior team member

Have regular one-on-one conversations to understand specific challenges and provide ongoing support

Extend deadlines for all of the team member's deliverables to reduce pressure
