A project team is delayed on a task that proved more complex than estimated. This critical task could affect the current iteration goals. Which two initial actions will help the team address this obstacle? (Choose two.)

When a critical task is delayed due to unexpected complexity, the team needs to understand why and assess the impact. Conducting a root cause analysis helps identify the underlying reasons for the complexity and delay, preventing recurrence and informing potential solutions. Reviewing and updating dependencies is crucial because a delay in a critical task will likely affect subsequent tasks. Understanding these updated dependencies allows the team to re-plan and mitigate further schedule impacts. Escalating to the project sponsor is premature; the team should first attempt to resolve the issue internally. Scheduling a retrospective is typically done at the end of an iteration or project, not as an immediate action for a current obstacle. Creating a risk management plan is a proactive activity performed earlier in the project lifecycle, not a reactive step for an immediate problem.
