Answer to Question 1

The four types of installation are direct, parallel, single location, and phased. Changing over from the old information system to a new one by turning off the old system as the new one is turned on is called direct installation. Parallel installation involves running the old information system and the new one at the same time until management decides the old system can be turned off. Single location installation involves trying out a new information system at one site and using the experience to decide if and how the new system should be deployed throughout the organization. Changing over from the old information system to a new one incrementally, starting with one or a few functional components and then gradually extending the installation to cover the whole new system is commonly called phased installation.
