Case Study: Unum achieves consolidation of 20+ HR apps and major cost savings with Workday Adaptive Planning

Unum improves its efficiency by consolidating 20+ HR applications

Unum, a Tennessee-based financial services company with 10,300 employees that serves 39 million people, was managing a fragmented IT landscape of 39 largely on‑premise HR and finance systems. The rigid environment created multiple information sources and heavy manual administrative work, limiting HR and finance teams’ ability to move quickly and make data‑driven decisions.

By implementing Workday, Unum consolidated more than 20 applications into a single cloud platform (cutting its estate from 39 to 17 systems), automated core HR processes, and launched HR Connect to streamline absence, billing, enrollment and more. The change produced clear business value: $200K net annual cost savings, $1.4M in upgrade cost avoidance, $1.7M annual head‑count savings, $2.5M reduced maverick spend, a reduction in financial year‑end roll forward from three days to one hour, faster hiring and higher adoption of performance tools.
