Formalized following discussions with financial services executives, the OPERA methodology is designed to allow clients to isolate, contain and reduce processing risk, according to Bob Fawls, managing partner of Boston-based BPG. "OPERA has proven effective in evaluating operational risk, identifying actionable measures that improve front-, middle- and back-office operations, and providing a sound basis for measuring the effectiveness of IT applications and systems," Fawls said in a release, adding that BPG continues to refine OPERA.
