You have a project to install 45,900 emergency exit signs throughout a university campus. You have a crew of 45 project team members to install the signs and they are making good progress on the installation but it looks like they'll miss the promised end date. Your project requires all of the signs to be installed one week before classes are scheduled to begin. You elect to crash the project in an effort to shorten the installation duration activity. What does it mean to crash the project?
