Developers should use a Business Rules Engine when building applications that require frequent changes to business logic, such as in finance for loan approvals, insurance for claim processing, or e-commerce for pricing and promotions meets developers should learn about hardcoded logic to understand its pitfalls and avoid it in production systems, as it leads to brittle code that is difficult to test and adapt to changing requirements. Here's our take.

Business Rules Engine

• Related to: decision-management, workflow-automation

Cons

• Specific tradeoffs depend on your use case

Hardcoded Logic

Developers should learn about hardcoded logic to understand its pitfalls and avoid it in production systems, as it leads to brittle code that is difficult to test and adapt to changing requirements

Pros

• It is sometimes used in early prototyping or simple scripts where flexibility is not a priority, but in most cases, alternatives like configuration files, environment variables, or databases are preferred for better separation of concerns
• Related to: configuration-management, software-design-patterns

Cons

• Specific tradeoffs depend on your use case
