Universal Containers introduced a new product and wants to track all associated cases that get logged. They are looking for an automated solution that would give the product's two lead engineers read/write access to all new cases that reference the new product. What should an administrator do to satisfy this requirement?

The most effective and direct solution is to use a combination of a predefined case team and a case assignment rule. An administrator can first create a predefined case team that includes the two lead engineers and grants them read/write access. Then, a case assignment rule can be configured to trigger when a new case is created with criteria matching the new product. A key action of this assignment rule is to automatically add the predefined case team to the case, thus granting the required access to the engineers in an automated fashion.

A. Create a queue and a criteria-based sharing rule. A queue is for record ownership, not for granting access to specific users who don't own the record. While a sharing rule could grant access, Case Teams are the more appropriate feature for collaborative case resolution.
C. Create a user-based sharing rule and an ad-hoc case team. Ad-hoc case teams are added manually to individual cases, which does not meet the requirement for an automated solution. User-based sharing rules are based on record ownership, not the case's criteria.
D. Create an auto-response rule and a public group. Auto-response rules are used to send automated email responses to customers who submit a case. They do not control internal user access to records.

1. Salesforce Help Documentation, "Set Up Case Teams": "You can set up case assignment rules to automatically add a predefined team to a case that meets specific criteria, such as the origin or record type of the case." This directly supports using an assignment rule to add a predefined team.

2. Salesforce Help Documentation, "Set Up Assignment Rules": Under the "Create Case Assignment Rules" section, the documentation lists available actions for rule entries, which includes the ability to "Add a predefined case team to a case." This confirms the mechanism for automation.

3. Trailhead by Salesforce, "Service Cloud for Lightning Experience" module, "Automate Case Management" unit: This unit explains that "Case assignment rules automate your organization’s support processes... You can also configure assignment rules to add a predefined case team to cases that match the criteria." This reinforces that the combination in option B is the standard, intended functionality.
