Salesforce Certified Platform User Experience Designer (Plat-UX-101) Exam Questions

Usability testing is a method of evaluating how easy and intuitive a product or service is to use by observing real users performing specific tasks. It can help identify usability issues, user needs, and user satisfaction. A goal of usability testing is to learn about the user's behavior and preferences, such as how they interact with the design, what they expect from the design, what they like or dislike about the design, and what they find confusing or frustrating about the design. By learning about the user's behavior and preferences, the UX designer can gain insights and feedback that can help improve the design and enhance the user experience.Reference:

A grid system is a set of columns and rows that help to organize and align the layout and content of a web page. The Salesforce Lightning Design System (SLDS) provides a responsive grid system that adapts to different screen sizes and devices. The SLDS grid system is based on the CSS Flexbox layout module, which allows for flexible and dynamic positioning of elements.The SLDS grid system consists of the following components1:

Containers: These are the outermost elements that wrap the grid. They have a fixed width that changes according to the breakpoints defined by the SLDS. Breakpoints are the points at which the layout changes based on the screen size.The SLDS has four breakpoints: small, medium, large, and x-large2.

Grids: These are the direct children of the containers. They are the main elements that define the grid structure. They have a display property of flex, which enables the flexbox layout.They can also have modifiers that control the alignment, direction, and wrapping of the grid items3.

Grid items: These are the direct children of the grids. They are the elements that contain the actual content of the page. They have a flex property that determines how much space they take up in the grid.They can also have modifiers that control the order, offset, and visibility of the grid items4.

A UX Designer should use the SLDS grid system to design responsively within the SLDS, as it provides a consistent and flexible way to create layouts that work across different devices and screen sizes.The SLDS grid system also follows the SLDS design principles and best practices, such as clarity, efficiency, consistency, and beauty5.

Adding section headers to a form can improve its readability by breaking it into logical chunks and providing context for the users. Section headers can also help users scan the form and find the information they need faster. Section headers can also reduce the cognitive load and increase the completion rate of the form .Reference:

: Salesforce Certified User Experience Designer Exam Guide, Section 3.2: Design for readability and clarity

: UX Designer Certification Prep: Design for Readability and Clarity, Unit 2: Design for Readability and Clarity

This allows users to quickly scan the form and identify the relevant fields, reducing the cognitive load and improving the overall user experience. Salesforce documentation statesthat ''by grouping related fields into sections, you can make your forms easier to read and understand'' [1].

Card sorting is a UX research method used to discover how people understand and categorize information. In a card sort, participants group ideas or information written on cards into different categories in a way that makes sense to them. The designer can use virtual cards, pieces of paper, or an online card sorting tool. Card sorting can help the designer to:

Assess the information architecture (IA) of a website or homepage

Learn how people understand different concepts or ideas, and how they feel about them

Understand where users expect certain content to be found

Get inspiration for labeling and grouping content or ideas

In this case, the designer wants to understand the structure and layout of the navigation menu for the Experience Cloud site. The designer can use card sorting to learn how users would group and label the pages or features of the site, and what categories or subcategories they would expect to see in the navigation menu. This can help the designer to create a user-friendly and intuitive IA that matches the users' mental models and expectations.

To conduct a card sorting activity, the designer should:

Define the goal and scope of the card sort

Choose the type of card sort (open, closed, or hybrid)

Choose the format of the card sort (moderated or unmoderated)

Select the cards and categories to use

Recruit and screen the participants

Run the card sort sessions

Analyze and interpret the results

Apply the findings to the design

The correct answer is B, have users sort the cards based on similar categories or groups. This is the main task of a card sorting activity, where users are asked to group the cards (representing the pages or features of the site) into categories or groups that make sense to them. The designer can then analyze the results to see how users organize and label the information, and use that to inform the design of the navigation menu.

The two UX design principles that are key to creating excellent mobile user experiences are:

Consistency across device experiences. This means that the design of a mobile app or website should match the design of the desktop version, as well as other platforms and devices. Consistency helps users to recognize and trust the brand, as well as to navigate and use the product more easily.Consistency also reduces the cognitive load and confusion for users who switch between different devices12

Prioritization of content and UI elements on the screen. This means that the design of a mobile app or website should focus on the most important and relevant information and actions for the user, and eliminate or minimize the unnecessary or secondary ones. Prioritization helps users to achieve their goals faster and more efficiently, as well as to avoid distractions and clutter.Prioritization also improves the readability and usability of the product on smaller screens34
