Which method of introducing change is associated with advantages like a clean break and immediate system availability but has high risks as a disadvantage?

The method of introducing change known for its advantages of a clean break and immediate system availability, while also carrying high risks, is Direct Changeover. This approach involves completely transitioning from an old system to a new system at a single point in time. When this method is employed, the old system is shut down, and the new system is put into use right away.

One of the primary advantages of Direct Changeover is the immediate availability of the new system. This allows organizations to start benefiting from the new features and improvements right away, without a transition period where both systems run simultaneously. It provides a straightforward and uncomplicated transition since there are no overlapping operations between old and new systems.

However, this approach is not without its pitfalls. The high-risk factor stems from the abruptness of the switch; if any problems arise with the new system, there is no fallback option or gradual transition available since the old system has already been decommissioned. It places a significant amount of pressure on the implementation phase, as everything must be thoroughly tested before the changeover occurs to mitigate potential issues.

In contrast, other methods like Parallel Running, Pilot Running, and Phased Implementation allow for a more gradual transition, reducing the risk of major disruptions by either maintaining both systems
