Installation Process
For this topic you need to know the difference between the main ways of performing a changeover to a new system. The IB refers to these as "installation" processes and you might also hear them called "implementation" processes. The main ways are:
- Direct changeover
- Pilot changeover
- Phased changeover
- Parallel changeover
You should be aware of the advantages and disadvantages of each method.
