Yolanda is the web designer for your company and you are the business analyst. You are working with Yolanda on a new website that your company will host. You'd like for her to create a mock-up of the

Mock-up prototype is not a recognized standard prototype classification in business analysis - horizontal and vertical are the accepted categories used to distinguish breadth-focused from depth-focused prototypes.

A vertical prototype implements full functionality for a narrow, specific feature or section of the system in depth, which is the opposite of showing broad surface-level features across the entire site.

A storyboard prototype uses a sequence of static images or frames to illustrate a user's journey through a process or workflow, rather than showing a broad interface with graphics and color direction.

A horizontal prototype focuses on the width of the system by presenting many features and interface elements across the application without building deep functional logic behind them. It is used to show customers the look, feel, basic graphics, and general direction of a project without significant back-end development investment. This matches the scenario where Yolanda is asked to show the site's appearance and basic functionality without implementing the actual underlying workings.
