Imagine that you are a project manager who was just assigned to a new project. You received no additional information except that your primary constraint is time and the initial cost estimates should be based on previously completed projects. Assume that you were able to find ways to gather the information you needed, and that you have already created a project plan and schedule. Now imagine that your team discovers discrepancies in the material and resource costs. Since you used predetermined cost estimates, how would you manage this problem to move forward?
