Consider an e-commerce site's feature that tells you by what time the parcel will reach a pincode. We discussed on architecture, whether the service that responds with the same should have the rules coupled with it or not.

Question

Accepted Answer

The rules for parcel delivery time estimation should be decoupled from the service for better maintainability and flexibility.

Decoupling the rules from the service allows for easier maintenance and updates without affecting the service itself.
Separating the rules also enables reusability across different services or components.
Using a separate rules engine or configuration file can provide flexibility to adjust the delivery time estimation logic without changing the service code.
For example, the rules for estimating delivery time based on distance, traffic conditions, and courier availability can be stored in a separate configuration file.
This approach follows the principle of separation of concerns and promotes better code organization.
