Which of the following implementation methods use both the old and new system simultaneously?
Show The implementation of the new system occurs when the old system is replaced by the new one. There are a new of ways of implementing a new system... Direct Changeover
The old system is stopped completely, and the new system is started. All of the data that used to be input into the old system, now goes into the new one. This is has its advantages...
But there are also disadvantages...
Sometimes a direct changeover is the only way to implement a new system. E.g. an aircraft's auto-pilot system can't have a new and old version running side-by-side, arguing about what to do! Parallel RunningThe new system is started, but the old system is kept running in parallel (side-by-side) for a while. All of the data that is input into the old system, is also input into the new one. Eventually, the old system will be stopped, but only when the new system has been proven to work. This is has its advantages...
But there are also disadvantages...
Phased ImplementationThe new system is introduced in phases (stages, or steps), gradually replacing parts of the old system until eventually, the new system has taken over. This is has its advantages...
But there are also disadvantages...
Pilot RunningThe new system is first of all piloted (trialled) in one part of the business / organisation (e.g. in just one office, or in just one department). Once the pilot system is running successfully, the new system is introduced to the all of the business / organisation. This is has its advantages...
But there are also disadvantages...
A 'pilot' is someone who guides others - someone who leads the way. On an airplane, the pilot guides all of the passengers safely to their destination. In a port, the pilot is a person on a small boat who guides large ships safely into the harbour.

What are the 4 implementation methods?Four common methods to implement a system[edit]. Parallel[edit]. Phased[edit]. Pilot[edit]. Direct[edit]. What are the three methods of implementation?There are three main methods used: phased implementation, direct changeover and parallel running. Phased implementation: A staged method whereby one part of the overall system that needs changing is changed.
What are the two types of system implementation methods?Methods of implementing systems include: direct cutover. parallel. phased.
