You priced out a project at 1,000 hours, assuming a grade 7 employee would be assigned. The line manager assigns a grade 9 employee. This will result in a significant cost overrun. The project manager should:
A. Reschedule the start date of the project based on the availability of a grade 7.
B. Ask the sponsor for a higher priority for your project.
C. Reduce the scope of the project.
D. See if the grade 9 can do the job in less time.
