Before 2002 the three disciplines lived in different parts of the organization. Governance sat with the board secretary and the general counsel. Risk lived in operations, treasury, and insurance. Compliance was a regulatory function inside legal or finance. Each ran its own register, its own taxonomy, and its own quarterly conversation with the executive team.
Sarbanes-Oxley changed the conversation in 2002. The new Section 404 obligations forced US-listed companies to document their internal controls over financial reporting, test them, and have an external auditor opine on them. That obligation crossed the historical seams. The controls that satisfied SOX 404 were also the controls in the risk register and in the policy library. Running them as three separate programs duplicated work, produced contradictory evidence, and missed the obvious efficiency play.
OCEG was founded the same year to formalize the integrated response, and the term "GRC" entered the working vocabulary. By 2007 Forrester and Gartner were publishing GRC market analyses; by 2010 the first integrated platforms (Archer, MetricStream, OpenPages, BWise) had emerged as a distinct category. The discipline has since expanded to absorb privacy (GDPR, CCPA), cyber (NIST CSF, ISO 27001), operational resilience (DORA), and ESG.
The business case for treating GRC as one program rather than three rests on four levers. First, deduplication: one control, one piece of evidence, many frameworks. Second, consistency: the same risk gets the same score regardless of which team looks at it. Third, speed to the board: the rollup builds itself instead of being assembled overnight before the meeting. Fourth, defensibility: a timestamped audit trail of every decision answers the regulator's first question without a fire drill.
