During execution, the project manager notices only one team member has a required technical skill, while future activities will need at least three people with that skill. Which two actions should the project manager take to prevent the team from being unqualified? (Choose two.)

To address the skill gap, the project manager should proactively develop the team's capabilities. Encouraging working in pairs and knowledge sharing allows the skilled team member to mentor others, transferring essential technical knowledge organically within the team. This builds internal capacity and resilience. Facilitating a training event with an external trainer provides structured, expert instruction, quickly upskilling multiple team members in the required technical skill. Both actions directly address the root cause by increasing the number of qualified individuals. Excluding activities from the roadmap is not a solution; it avoids the problem and impacts project scope. Teaching the entire team the new skill is impractical for one project manager with limited time. Increasing time estimates for activities only delays the problem and does not resolve the lack of skilled personnel.
