02  THE CHALLENGE

The HR team knew AI could transform how they work — but had no reliable way to answer the harder question: where, exactly, to apply it, and how to prove the value. Reporting, data cleaning, and reading open-text feedback were absorbing hours of manual effort every week.

03  THE APPROACH

A GPS for AI

Reejig translated the organization’s job data into its Work Ontology® — breaking every role into tasks, mapping required skills, and scoring AI potential. Instead of guessing, teams got a precise map of where to apply automation, paired with purpose-built prompts in Copilot. 04 The outcome Hours back, function by function Across seven HR functions the same work now takes a fraction of the time — an average of 5.3 hours saved per task, with 78% of AI outputs meeting or exceeding what the practitioners expected. The map, not the tooling, was the unlock.
