parallel-prototypes

To compare UX design variants in parallel, define 2-3 separate prototype files for a screen or flow, evaluate them against a shared hypothesis, and log outcomes to identify the winning design decision while cleaning up losers.

Parallel prototype testing is running 2-3 interface approaches simultaneously to accelerate decision making. Use it when deciding between distinct layouts, copy variations, or user flows and when a clear test hypothesis can be articulated.

You evaluate different layout or flow options by building 2-3 separate variant files and running them through a parallel comparison workflow. This ensures all design choices are tested fairly under identical hypothesis conditions simultaneously.

Yes, a clearly articulated test hypothesis is required before comparing interface approaches. The workflow evaluates all 2-3 variants against this specific hypothesis to ensure a fair comparison and accurate design decision.

After a UX comparison is completed and a winner is selected, the losing variants are cleaned up to keep the codebase focused. The evaluation outcome is also logged to a prototype log for future reference.
