NASA Lessons Learned Information System. Appears access is restricted to NASA and approved contractors.The NASA LLIS is an on-line, automated database system designed to collect and make available for use the NASA lessons learned from over forty years in the aeronautics and space business. The LLIS enables the knowledge gained from past experience to be applied to current and future projects. Its intent is to avoid the repetition of past failures and mishaps, as well as the ability to share observations and best practices. Through this resource, NASA seeks to facilitate the early incorporation of safety, reliability, maintainability, and quality into the design of flight and ground support hardware, software, facilities, and procedures.
There are two portals through which the NASA Lessons Learned Information System data may be accessed. The "LLIS" (Lessons Learned Information System) portal should be used to access the data from a NASA site or NASA network connection, including a NASA dial-in line. The "PLLS" (Public Lessons Learned System) portal should be used to access the data from all other (non-NASA) sites and network connections. The PLLS replaces and enhances the now retired NASA International Safety Lessons Learned (ISLL) access portal. The LLIS and the PLLS contain the same lessons learned and are updated concurrently with new lessons.
