When should parameters be added to a mapping for best practice?

Adding parameters to a mapping after the mapping has been tested is a best practice because it enables developers to refine and enhance the mapping's functionality based on real test results. Once the mapping is operational and certain aspects have been validated, incorporating parameters allows for dynamic changes and adjustments without needing to reconfigure the entire mapping from scratch. This phased approach ensures that any changes made through parameters will not disrupt a working mapping, allowing for a more stable and controlled integration process.

By implementing parameters post-testing, the mapping remains flexible and can adapt to changing requirements, improving maintainability and scalability in the long run. This approach also helps avoid potential issues that might arise from introducing parameters too early in the design process, when the underlying logic of the mapping is still in flux.
