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 provides UI components, icons, fonts, colors, and more that follow the best practices and accessibility standards of Salesforce. One of the features of SLDS is the ability to create custom themes that reflect the brand identity and personality of a company or an app. Custom themes can be implemented using design tokens, which are variables that store the values of the UI elements, such as colors, sizes, spacing, fonts, etc. Design tokens can be overridden or customized to change the appearance of the UI components without modifying the CSS or HTML code. To implement the company colors in all UI components, such as buttons and icons, using a custom theme, the UX designer should use the design tokens prefixed with "brand", such as $brand-primary, $brand-secondary, $brand-accessible, etc. These design tokens control the color scheme of the UI components and can be assigned the values of the company colors. For example, to change the color of the primary button to the company's blue color, the UX designer can use the following design token:
$brand-primary: #0070d2;

The users can improve their end-user experience by favoriting the often used object and personalizing the navigation bar. Favoriting the object allows the users to access it quickly fromthe Favorites menu in the header. Personalizing the navigation bar allows the users to add, remove, or reorder the items that they use frequently. These features do not require the administrator to create a new app or modify the existing one, and they can be customized by the users themselves according to their preferences and needs.

Q Tabs are a type of SLDS component that can be used to organize and consolidate content on a record page.
Q Tabs are a variant of the Tabs component that are designed for use in the Lightning App Builder. Q Tabs allow users to switch between different views of related information within the same context. Q Tabs can also be nested to create subtabs within a tab. Q Tabs can help UX designers to create content-rich record pages that are easy to navigate and consume. Q Tabs can also help to reduce clutter and scrolling on a record page by grouping related content into tabs. Q Tabs can be customized with different icons, labels, and badges to indicate the type and status of the content in each tab. Q Tabs can also be configured to load content dynamically or on demand, which can improve the performance and user experience of the record page.

Card sorting is a technique that helps UX designers understand the mental model of users and how they organize information into categories. Card sorting involves giving users a set of cards, each with a piece of information or a feature, and asking them to sort them into groups that make sense to them. The designer can then analyze the results and identify patterns, similarities, and differences among the users' categorizations.
Card sorting can help the designer suggest a suitable architecture for the new internal community, based on how the employees think about the site's content and functionality. Card sorting can be done in person or online, using tools like OptimalSort or UserZoom1. References:

A diary study is a research methodology that involves asking participants to record their thoughts, feelings, behaviors, and activities over a period of time, usually in response to prompts or questions from the researcher1. A diary study is suitable for Cloud Kicks (CK) to conduct discovery phase research to understand more about the customers' purchasing habits, as it will allow them to remotely observe customers' buying patterns over the course of a 2-month period. A diary study will also provide rich and contextual data on the customers' needs, preferences, motivations, and pain points, as well as the factors that influence their purchasing decisions1.
