XYZ Corporation wants to ensure that every attempt by a developer to check a rule into a certain ruleset version is reviewed before that rule is allowed to be checked in. The rule should be automatically sent back to the developer without being checked in if all warnings are not justified and the fields on the history tab are not complete.

Client XYZ Corp implemented Pega Customer Service.
A customer service representative (CSR) needs to launch multiple applications to manually update information to keep dam synchronized across systems. The applications are built in different technologies, decreasing the CSR's efficiency in handling customer requests. The client has a requirement to launch all applications from the PLCJA Customer service application. The client requires that data Mows to and from the Pega Customer Service application to the other applications used by the CSR. Changes made in any one of the systems is reflected in other relevant systems. This results in the CSR handling customer requests more efficiently and spending less time manually updating dependent applications.
