A new project is about to start, and the risk manager wants to review some...

Lessons learned from previous projects are critical for effective risk identification because they provide insights into what risks materialized, how they were managed, and what could have been improved. According to the PMBOK® Guide:

“Lessons learned from previous projects are organizational process assets that should be reviewed during risk identification to avoid repeating past mistakes and to leverage successful risk responses.”

— PMBOK® Guide, 6th Edition, Section 11.2.2.1 (Organizational Process Assets)

These assets enable proactive identification and management of similar risks in the new project.
