Explanation: The conceptual approach of desirable, feasible, and viable describes how to evaluate design solutions based on three criteria:
Desirable: The solution meets the needs and wants of the users and stakeholders. Feasible: The solution can be implemented with the available resources and technology.
Viable: The solution can generate value and sustain itself in the market and environment. By incorporating human-centered design, CK is aiming to create design solutions that are desirable for its Sales team and customers, feasible with the Salesforce platform and tools, and viable for its business goals and strategy.
T-shirt sizing is a methodology that can be used to roughly estimate the work required for each item in a sprint backlog. It involves assigning a size category (such as XS, S, M, L, XL) to each item based on its complexity, effort, and uncertainty. T-shirt sizing is a relative estimation technique that allows the team to compare items and prioritize them accordingly. It is also a quick and easy way to get a high-level overview of the scope of work without getting into too much detail.

Explanation: Dynamic Actions are a feature that allows the UX Designer to customize the actions that appear on the Highlights panel of a Lightning record page based on criteria such as record status, user profile, or field value. This way, the UX Designer can declutter the Highlights panel and show only the relevant actions for each record. Dynamic Actions can be configured in the Lightning App Builder instead of the page layout editor, which gives more flexibility and control to the UX Designer.

Explanation: To document user goals, common tasks, and pain points for a new service experience, the tool that a UX Designer should use is user personas. User personas are fictional representations of the target users, based on real data and research. User personas help the designer to understand the needs, motivations, behaviors, and expectations of the users, as well as their challenges and frustrations. User personas can also help the designer to prioritize features, create scenarios, and design solutions that are relevant and meaningful for the users.

Explanation: The best place on the SLDS website for the designer to find accessible HTML and CSS used to create components along with implementation guidelines is the Component Blueprints1. Component Blueprints are framework-agnostic, accessible HTML and CSS that provide the basic structure and style for Lightning components1. The designer can use the Component Blueprints to create custom Lightning Web Components that are consistent with the Lightning Design System. Design Tokens (B) are not the best place to find HTML and CSS, as they are variables that store design attributes, such as colors, fonts, and spacing2. Development Tools © are not the best place to find implementation guidelines, as they are tools and resources that help developers build and test Lightning components, such as VS Code extensions, LWC recipes, and Playground3.

Explanation: A style guide is a document that defines the visual identity and branding of a company, such as the logo, color palette, typography, iconography, imagery, and tone of voice. It helps ensure consistency and coherence across different platforms and channels, and communicates the company’s values and personality. When implementing a company’s brand on Salesforce, the style guide should be the source of truth for consistency, as it provides the guidelines and rules for applying the brand elements to the user interface. A style guide can also include a pattern library, which is a collection of reusable UI components and design patterns that follow the style guide. A design principle is a statement that expresses the core values and goals of a design process, and guides the decision making and evaluation of a design solution. The Salesforce Lightning Design System (SLDS) is a set of design guidelines and resources for creating consistent and beautiful user experiences on the Salesforce platform. It can be used as a reference and a foundation for customizing the UI according to the company’s style guide.
