What is a Vertical Prototype?

A vertical prototype, also known as a "depth prototype," is a type of prototype that focuses on a single feature or aspect of a product, providing a detailed and comprehensive representation of that specific feature. Unlike horizontal prototypes, which aim to demonstrate a wide range of features with limited depth, vertical prototypes prioritize depth and accuracy in showcasing a particular functionality or component.

Why is a Vertical Prototype Important?

Vertical prototypes are especially useful when a specific feature or functionality is critical to the success of a product or when there is a need to thoroughly test and refine a complex aspect of the product. They allow for in-depth evaluation and validation, helping to ensure that the core features of a product meet user expectations and requirements.

How to use a Vertical Prototype?

Key characteristics of a vertical prototype include:

Detailed Feature Representation: It provides an in-depth and often fully functional representation of a specific feature, allowing stakeholders to see how that feature will work in the final product.

Limited Breadth: Unlike horizontal prototypes, which cover multiple features, a vertical prototype may only address one feature or a tightly integrated set of features.

Specific Focus: Vertical prototypes are typically used to test and refine the functionality of a critical or complex aspect of the product. This helps ensure that this aspect functions correctly and meets user requirements.

Realistic User Interface: The user interface elements related to the specific feature are usually implemented realistically, giving stakeholders a clear idea of how users will interact with that part of the product.

In-Depth Testing: Vertical prototypes are valuable for rigorous testing and validation of a specific feature. They help identify and address potential issues or challenges early in the development process.

Time-Consuming: Creating a vertical prototype can be more time-consuming than a horizontal one, as it requires detailed implementation of a single feature.
