• Describe the role and responsibilities of the project sponsor in the subject organization. Why did this affect the project schedule development?
• The project manager needs direction from the project sponsor concerning whether to base the schedule on best time, least cost, or least risk. Why is this important for developing the project schedule?
• Which project organizing or initiating documents, or artifacts, would typically provide an answer to the project managers question? Explain.
