The project must be completed by December 1, so this is an example of schedule constraint. 1 is incorrect because this is not an assumption. 2 is incorrect because this answer is not valid for this question. 3 is also incorrect because this is not a cost constraint. The $10,000 penalty is only assessed if the project does not complete on time. In addition, in some instances it is more cost effective to be late with the project deliverable, accept the penalty, and deliver a higher-quality project.
