design-an-interface

To compare different API designs, you need to generate at least three distinct interface options for your module and evaluate their trade-offs. This process includes providing usage scenarios for common calls, errors, and evolution to inform your decision.

Evaluating multiple interface designs prevents teams from locking into a single API shape too early. By comparing radically different options, you avoid costly and error-prone refactors later, ensuring the chosen module boundaries support future evolution effectively.

The best way to evaluate API trade-offs is to apply specific criteria such as simplicity, flexibility, and maintainability. By generating usage scenarios for each design showing how they handle common calls and errors, you can clearly justify which option is best.

Yes, you can use this approach to reshape existing module boundaries. By proposing and comparing radically different API designs for the module, you can evaluate the public API options and select a new design direction that better fits your current architecture.

To generate divergent API designs, you create at least three radically different interface proposals for the same module. You then document the specific trade-offs and justifications for each design, ensuring you have distinct options to compare before finalizing the boundaries.
