Parallel running

Definition

Parallel running is the practice of operating an old system alongside a new system during the transition phase of implementing new technology or processes. This approach allows for a smoother transition as it enables users to compare results, identify issues, and ensure that the new system functions correctly before fully committing to it. It also reduces risks associated with switching to the new system by allowing businesses to verify data integrity and operational continuity.

5 Must Know Facts For Your Next Test

1. Parallel running allows organizations to validate that the new system meets all operational requirements without losing access to the old system.
2. This approach is particularly useful in ERP implementations, where data accuracy and process consistency are critical.
3. Parallel running can lead to increased operational costs due to the need for resources to manage both systems simultaneously.
4. While parallel running can extend project timelines, it ultimately helps mitigate risks associated with adopting a new system.
5. Successful parallel running requires thorough planning, including training users on both systems and establishing clear metrics for comparison.

Review Questions

• How does parallel running facilitate a smoother transition during ERP implementation?
  • Parallel running facilitates a smoother transition by allowing organizations to operate both the old and new systems at the same time. This enables users to compare outputs from both systems, ensuring that the new ERP is functioning as expected before fully transitioning. It also provides a safety net, as users can revert to the old system if critical issues arise during the switch, reducing anxiety about making the change.
• Discuss the potential drawbacks of using parallel running as a strategy for implementing a new ERP system.
  • The potential drawbacks of using parallel running include increased operational costs since resources are needed to support both systems. It can also create confusion among users who have to navigate two different systems simultaneously. Additionally, parallel running can extend project timelines as organizations may find themselves spending more time troubleshooting issues that arise when comparing outputs from both systems.
• Evaluate how effective training on both old and new systems can impact the success of parallel running during an ERP implementation.
  • Effective training on both old and new systems significantly impacts the success of parallel running by ensuring that users are comfortable and proficient with each system's functions. Well-trained users are better equipped to identify discrepancies between outputs and can more effectively troubleshoot issues that arise. This training fosters confidence in using the new system while still relying on the old one, ultimately leading to a smoother transition and successful implementation.
