Welcome to the NASA Public Lessons Learned System!

The NASA Lessons Learned system provides access to official, reviewed lessons learned from NASA programs and projects. These lessons have been made available to the public by the NASA Office of the Chief Engineer and the NASA Engineering Network. Each lesson describes the original driving event and provides recommendations that feed into NASA’s continual improvement via training, best practices, policies, and procedures.

NOTE: If you are a NASA user, you may access the internal site on the NASA Engineering Network to view and share lessons.
