Lessons Learned Branch (LLB)


The Lessons Learned Branch collects and analyzes lessons both best practices and issues from major operations and training exercises conducted by the operating forces; collaborates with medical subject matter experts to identify Doctrine, Organization, Training, Materiel, Leadership & Education, Personnel, and Facility (DOTMLPF) gaps and potential solutions; and disseminates lessons and best practices with the Army and the Army Medical community of practice to optimize unit and Soldier performance and effectiveness.


Joint Lessons Learned Information System (JLLIS)

JLLIS is the DoD authoritative system for gathering, developing, and disseminating lessons learned for the Armed Forces that enables Joint Lessons Learned Program (JLLP) and Army Lessons Learned Program (ALLP) information and knowledge management.  The JLLIS facilitates the collection, tracking, management, sharing, collaborative resolution, dissemination, and archiving of information to improve the development, design, and readiness of the Joint Force.

The LLB migrated its repository to JLLIS. In addition to the documents loaded by the LLB, JLLIS provides a repository of After Action Reports and observations from other Army medical units and Sister Services. The information is sorted in three Communities of Practice (COPs): After Action Reports (AARs), Standard Operating Procedures (SOPs), and Tactics, Techniques, and Procedures (TTPs).

Before accessing JLLIS, users must first pre-register with the Joint Training Platform.

JLLIS also provides reference document, user guides, capability briefs, brochures, and virtual classrooms to facilitate its use.
