Background: The system will use an external payment provider. If a different payment provider is chosen, the system needs to be able to quickly adapt to the new payment provider.
Source: Development team
Stimulus: New payment provider needs to be integrated
Reaction: Integration can be done without changing any other subsystem or component
Metric: The following applies to all other subsystems:
- The source code remains identical
- Compile, build and test processes remain identical
- Deployment, installation and configuration remain identical
