Which set of rules can a strategy designer change?

The ability of a strategy designer to change rules is specifically tied to their role and the permissions granted within the context of a change request. When options are outlined in relation to who is assigned to a particular change request, it becomes clear that the strategy designer is only permitted to modify those rules that are explicitly assigned to them within that request. This focused permission structure promotes accountability and localized control over specific rules without impacting the entire set of rules managed by others, such as system architects or revision managers.

In this context, the first choice refers to all rules included in all change requests, which would be too broad, potentially allowing the strategy designer access to rules they are not responsible for. The third choice mentions all rules associated with the application by the system architect, but this access should be limited to roles specifically defined to encourage adherence to organizational protocols. The fourth option concerns rules assigned to the revision manager, further distancing the strategy designer from control over those specific rules.

Thus, the option that states a strategy designer can change all rules in the change request that is assigned to them accurately reflects the structured governance model of rule management within the Pega platform, ensuring clarity in roles and responsibilities while allowing the strategy designer the necessary flexibility to implement changes effectively.
