Ensuring that each existing article type has a corresponding knowledge article type that matches its structure and content is a factor that a consultant should consider as part of the migration strategy for Knowledge articles. An article type is a template that defines the layout, fields, and data categories for an article. An article type can be customized to suit different types of content or audiences. When migrating articles from an external database to Salesforce Knowledge, it is important to ensure that there is a matching article type for each existing article type in Salesforce Knowledge, so that the articles can be imported without losing any information or formatting.

Entitlements and milestones are Service Cloud features that help you track and ensure service level agreements (SLAs) on customer cases. Entitlements define the levels of support that customers are eligible to receive based on their products, service contracts, or warranties. Milestones define the critical steps in your support process, such as first response time or resolution time, and track whether they are completed on time.
You can use entitlement processes to automate actions when milestones are approaching, violated, or completed, such as sending email notifications, assigning cases to queues or users, or changing field values.

The consultant should explain that Average Speed of Answer (ASA) is skewed by calls that are quickly answered. ASA is a metric that measures the average time that callers wait in the queue before being connected to an agent. ASA can be affected by outliers, such as calls that are answered immediately or calls that are abandoned after a long wait. ASA can be misleading if it does not reflect the typical experience of a caller or the performance of an agent. Verified References: : https://help.salesforce.com/s/articleView?id=sf.
