Center for Army Lessons Learned

Driving Army Change

About Us

How CALL Drives Army Change CALL drives Army change through leading the Army Lessons Learned Program (ALLP) and delivering timely and relevant information to resolve gaps, enhance readiness, and inform modernization. To accomplish this CALL, executes the Army Annual Plan collecting, analyzing, disseminating, integrating, and archiving lessons learned from tactical to theater/strategic levels. CALL researches root-cause analysis, defines trends/themes, coordinates with the lessons learned community of interest, and initiates product development. CALL's multimedia-based products are disseminated through a variety of print and electronic formats, with the web-based Joint Lessons Learned Information System (JLLIS) serving as the central repository. As emerging issues are discovered, CALL incorporates those into the Army Lessons Learned Forum, to facilitate continuous development, improvement, and adaptation of material and non-material solutions across the DOTMLPF-P spectrum. CALL modernization, and interoperability activities support sister services, international, and interagency bilateral staff talks, mil-to-mil engagements, and agreed-to-actions. This holistic approach to lessons learned drives Army change and fosters Army readiness.
CALL's MISSION The Center for Army Lessons Learned leads the Army Lessons Learned Program and delivers timely and relevant information to resolve gaps, enhance readiness, and inform modernization.
CALL's VISION The Center for Army Lessons Learned is the Army's daily focal point for adaptive learning based on lessons and best practices from the total force and provides timely and relevant knowledge to the warfighter and our unified action partners utilizing integrated systems and interactive technology in order to simplify winning in a complex world.
