Case Study: TietoEVRY unifies its 24,000-strong merged workforce and gains agility with Workday Adaptive Planning

TietoEVRY unifies its newly merged global workforce with one HR system

TietoEVRY, a Finland‑headquartered leader in Nordic digital services, faced the challenge of unifying two merged companies (Tieto and EVRY) that together employed about 24,000 people but still operated on separate HR systems, recruiting tools and workflows. This fragmentation slowed decision‑making, hindered data sharing and limited the newly formed company’s ability to scale and operate as one cohesive organization.

The company implemented Workday as a single HR system, delivering a unified data core, common processes and improved remote‑working support in a five‑month, fully remote deployment. Results included 96% of former EVRY managers accessing Workday in the first month, a 66% headcount increase without growing the global support team, faster access to people data for managers and finance, streamlined approvals and clearer organizational visibility across the merged company.
