Mack Roe walks to Anna’s desk where Chip is standing and says, “The last program has been tested and incorporated into the system test. The results indicate that the system is finally complete. Every program and subsystem is working as planned. The whole system checks out. Testing has been thorough and exacting, with all the problems and program bugs satisfactorily resolved. I’ve reviewed the deliverables, and each one has been developed into programs. I’ll leave you two to install it and then celebrate.”
“That’s fantastic!” Anna replies as Mack leaves. “We’ve been anticipating this moment for a long time. We now have the task of installing the system. I’ve checked with Mike Crowe, and all the hardware has arrived and has been installed. The computers have been connected, and the network software has been installed. Why don’t we make a list of the tasks to be completed?”

1. Describe procedures that should be designed to create automatic backup. In a paragraph, be sure to consider the pros and cons of these procedures.
2. List security measures that should be taken to prevent unauthorized persons from using the computer system.
3. Outline a disaster recovery plan for the new computer system you have created for CPU. In particular focus on the teams that will be responsible for managing a crisis.
