the old and new systems are run in parallel.
The correct answer and explanation is :
The correct answer is:
“replaces the old one on an appointed day.”
Explanation:
The direct cutover conversion strategy, also known as the “big bang” approach, involves switching from an old system to a new system all at once, on a predetermined, appointed day. This means that the old system is completely replaced by the new one, with no running of both systems in parallel. Once the switch is made, the old system is completely abandoned, and the new system takes over all functions.
Here are the key characteristics of the direct cutover strategy:
- Complete Switch on a Specific Day: The transition to the new system happens at a set point in time. There is no overlap or phased transition period.
- No Parallel Running: Unlike other strategies like parallel running or phased conversion, the direct cutover does not involve running both systems concurrently. Once the new system is live, the old system is no longer used.
- Risk Consideration: The major risk with this strategy is that if something goes wrong with the new system, there is no fallback on the old system. Since the old system has been fully replaced, it can lead to significant operational disruptions if the new system is not functioning as expected.
- Advantages: One of the main advantages of the direct cutover approach is that it’s quick and requires less time and resources compared to other strategies that involve running both systems in parallel or in stages. There is no need for ongoing support for two systems.
- Challenges: However, the major challenge is the potential for operational interruptions if the new system encounters issues post-launch. Extensive testing and preparation are essential to ensure a smooth transition.
In summary, the direct cutover strategy is typically used when an organization needs to make an immediate switch to a new system, often because of deadlines or the need for a clean break from legacy systems.
Here is a diagram illustrating the direct cutover conversion strategy. It shows how the old system is fully replaced by the new system at a specific point in time, with no parallel running. The new system begins its operation immediately after the appointed day.
