Select an asset of your choice. For example you may select an appliance in your home, office, or in another place that have been in use for many years and you are thinking is time to replace it by a new one.
The new one or challenger, that you think should replace the defender, is supposed to do a similar operation than the old one. But the new appliance has its costs.
After selecting the defender equipment and the challenger, you first must write a short review of them, a background information of both appliances, and then express your opinion of why the old equipment should be replaced and the possible costs of doing the replacement. Does it worthwhile to replace the old appliance now?
