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.
