Creating a prototype from a specification

Prototyping transforms written requirements into something tangible that users can interact with. Once the core features are defined, teams can create a basic clickable model using tools like Figma or Miro. This prototype serves as an early test of how real people navigate the flows described in the spec. For instance, a checkout process that looks straightforward in writing might reveal friction when users struggle to find the “Continue as guest” option.

These small insights are powerful. They highlight where requirements need clarification, where steps can be simplified, or where functionality is missing altogether. Teams can then revise the specification to include clearer instructions, adjusted labels, or an updated flow that matches how users actually behave. Testing at this stage ensures that the product spec evolves from assumptions into verified directions, making development smoother and more aligned with real-world use.
