For many years, APPEL has advanced NASA’s knowledge through publications including INSIGHT, the NASA Knowledge Journal, ASK OCE, and ASK Magazine, which featured articles, white papers, columns, and more that shared practical lessons in project management, systems engineering, and organizational learning. Together, these publications represent a substantial archive of expertise and insights from practitioners and subject matter experts across NASA and beyond. 

Selected highlights from prior publications are listed at Knowledge Essentials, and some additional APPEL publications are available via the NASA Technical Reports Server.  If you are looking for specific content from past publications, please contact us—we will be glad to locate that information in our archive and provide the materials you need.
