Is the project schedule realistically sufficient to
execute the scope of work and meet project objectives
at an acceptable level of risk? That is, does it have
buy-in from the project team and the performing
organization's management? If not, is it clearly
understood and accepted by the project stakeholders
(i.e., is it an assumption that has been agreed to and
documented)? If not, is there a potential for loosening
requirements and reducing project scope to get to a
realistic schedule?
