Creating a Salesforce console for service and enabling the knowledge sidebar on the case page layout is a solution that can enable articles to be suggested to agents based on information they are typing into the case.
A Salesforce console for service is a workspace that allows agents to manage multiple cases and interactions on a single screen. The knowledge sidebar is a feature that shows suggested articles based on the case subject, description, or other fields in the console.

To route cases from social channels efficiently within a limited timeframe, configuring custom case assignment rules is recommended. These rules can automate the distribution of cases based on specific criteria, ensuring that cases are promptly assigned to the appropriate agents or queues for timely resolution.

Creating reports to analyze call data in order to understand peak times and ensure adequate staffing and setting up a Salesforce Customer Community that will allow customers to create cases online are recommendations that a consultant should suggest to help decrease customer wait times. These recommendations can help reduce the volume and duration of phone calls and improve customer satisfaction by providing alternative and convenient channels for customers to get support. For example:
* Creating reports to analyze call data in order to understand peak times and ensure adequate staffing can help optimize the resource allocation and scheduling of support agents. Reports can show metrics such as call volume, call duration, call abandonment, or service level by time, date, or location. Reports can also be used to identify trends, patterns, or issues that affect the call performance and customer experience.
* Setting up a Salesforce Customer Community that will allow customers to create cases online can help divert some of the phone calls to a self-service portal. Customers can use the community to search for answers, create cases, track case status, or interact with other customers or agents. A community can also provide features such as knowledge articles, chatbots, live chat, or feedback mechanisms.

Explanation
Search Activity Gaps is a Knowledge dashboard that a consultant should use to know where to focus its efforts next after implementing Knowledge Centered Support. Search Activity Gaps shows the number of searches that returned no results, no articles, or no clicked articles. This can help identify the topics or keywords that need more or better articles to satisfy customer needs. Verified References: :
