Frequently asked questions

What are the core enterprise systems?
The core enterprise systems are ERP for finance and operations, CRM for customers, HCM for people, ITSM for IT services, identity and access management, and a data platform for analytics.
How do enterprises reduce application sprawl?
Inventory every application with a SaaS management or enterprise architecture tool, map overlaps and costs, consolidate on platforms, and govern new purchases through procurement and IT.

Linking identity to the HR system automates access when people join, move or leave, which removes manual tickets and closes security gaps from orphaned accounts.
