A work manager is an application user who performs work but has the training and ability to alter selected business rules that application developers have delegated. Generally, users in such roles cannot create new rules, and are limited in the types of changes they can make to rules delegated to them to maintain.
The standard access role name PegaRULES:WorkMgr4, referenced in an access group, conveys work manager capabilities to a user.
In many cases, work managers access Pega 7 applications though the facilities defined by the standard portal rule named WorkManager, or a custom portal rule derived from that standard portal rule.
