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
