Add links to printable tipsheets or training videos: This can help the Sales team to learn and review the key functions and processes at their own pace and convenience.The tipsheets or videos can be hosted on internal or external websites, and can be added to the custom help menu section in the Help Menu settings1. The links can have descriptive labels and icons to make them easy to identify and access.

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.Reference:

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.Reference:

Typography, color, and imagery are visual design elements that can be used to create a consistent and recognizable corporate style and branding. Typography refers to the choice and use of fonts, sizes, weights, and spacing to convey meaning and hierarchy. Color refers to the selection and application of hues, shades, tints, and tones to create contrast, harmony, and mood. Imagery refers to the use of photos, illustrations, icons, and graphics to communicate messages, concepts, and emotions.

Tiles are standard components that display records or objects as a collection of boxes that contain a photo and additional information1. Tiles are suitable for Cloud Kicks (CK) to display contact information, including avatar, name, and title, for people who are related to a customer on a Record page, as they provide a compact and visual way to show the relevant data.Tiles also allow users to interact with the records by clicking or tapping on them1.Tiles can be customized to fit the available space and layout of the Record page2.Components - Salesforce Lightning Component Library,Tiles - Lightning Design System Interactive cards are compact components that can displayinformation such as avatars, names, and titles in an organized way. Additionally, Interactive Cards are designed to be responsive and can be used to display information on smaller screens, such as mobile devices, without taking up too much space. This makes them ideal for CK's use case, as they can display all of the required information within the limited title space. For more information, see the Salesforce Lightning Design System documentation (https://lightningdesignsystem.com/components/cards/#interactive-cards).

The designer should consider the traits similar to customer personas when selecting users for testing. Customer personas are fictional representations of the target users of a product or service, based on user research and data. Customer personas help the designer to understand the needs, goals, behaviors, and preferences of the users, as well as their pain points and challenges. Customer personas also help the designer to empathize with the users and design solutions that meet their expectations and requirements. [UX Designer Certification Prep: User Research], [UX Designer Certification Prep: User Roles and Personas] When selecting users for testing, the designer should aim to recruit users who match the traits of the customer personas as closely as possible. This ensures that the users who participate in the testing are representative of the actual or potential users of the product or service, and that the feedback and insights gathered from the testing are valid and reliable. Selecting users who have traits similar to customer personas also helps the designer to evaluate the usability and user experience of the product or service from the user's perspective, and to identify and prioritize the areas for improvement. [UX Designer Certification Prep: User Research], [UX Designer Certification Prep: User Testing and Evaluation] Traits dissimilar to customer personas, traits similar to friends and family, and traits of the most common demographic and ability are not criteria that the designer should consider when selecting users for testing. These criteria can lead to biased or inaccurate results, as they do not reflect the diversity and complexity of the user population. Users who have traits dissimilar to customer personas may not have the same needs, goals, or expectations as the target users, and may provide feedback that is irrelevant or misleading. Users who have traits similar to friends and family may not be objective or honest in their feedback, and may have a different level of familiarity or expertise with the product or service than the target users. Users who have traits of the most common demographic and ability may not account for the variations and differences among the target users, and may exclude or marginalize the users who have special needs or preferences.
