What is a "mockup" used for in localization?

A "mockup" is used in localization primarily as a visual representation that illustrates how localized content will appear in its intended context. This is essential for assessing the integration of localized text with user interfaces, applications, or webpages, allowing stakeholders to visualize the overall design and layout prior to final implementation. By providing a concrete example of how translated content will look, mockups facilitate discussions about design adjustments and ensure that the target audience will have a satisfactory user experience.

The use of mockups also aids in identifying potential issues related to text expansion or contraction due to translation, ensuring that visual elements function well with the localized content. Consequently, they serve as an important tool in the localization process, helping to align expectations and make necessary adjustments before development reaches its later stages.
