Sandra is a project manager for an effort that requires 12 months. During the seventh, eighth, and ninth months, she needs two individuals with special qualifications. The functional manager has promised that these individuals will be available two months before they are needed. If Sandra does not assign them to his project at that time, they will be assigned elsewhere and she will have to make do with whoever will be available later. What should Sandra do? Do you have to make any assumptions in order to defend your answer?
