The terms Source and Target systems are commonly used in user provisioning software solutions. The source represents the system or systems that contain the data needed for the user lifecycle processes. Typically, this is a Human Resource (HR) or Student Information System (SIS) system containing user, job, or student information. The target represents the downstream system or systems that the source data will be synchronized to. Typically, this is Active Directory, Azure AD, Google Workspace, or other software applications.
