Extract hard-coded configuration values into variables, parameters, or templates to improve reusability and simplify maintenance. When the same value is used in multiple places or might need to change in the future, define it once and reference it throughout your configuration files.

Examples:

1. For build scripts with multiple parameters: ```yaml

   Instead of:

   • script: make run TARGET_ARCH=arm64 DEPLOY_AND_RUN=false RUNTIME_FLAVOR=CoreCLR STATIC_LINKING=true

Use:

• script: make run TARGET_ARCH=$ DEPLOY_AND_RUN=$ RUNTIME_FLAVOR=$ STATIC_LINKING=$ ```

1. For repeated configuration values: ```yaml

   Define once:

   variables: timeoutPerTestCollection: 180

Reference where needed:

jobParameters: timeoutInMinutes: $ ```

This practice reduces duplication, centralizes configuration management, and makes future updates more efficient and less error-prone.
