Joint Lessons Learned
The Joint Lessons Learned Division (JLLD) fulfills the Chairman's Title 10 responsibility of formulating policies for gathering, developing, and disseminating joint lessons learned for the armed forces. It's primary objective is to enhance joint force readiness and effectiveness by contributing to improvements in doctrine, organization, training, materiel, leadership and education, personnel, facilities, and policy (DOTMLPF-P).

The Joint Lessons Learned Program consists of five phases: discovery, validation, resolution, evaluation, and dissemination. (Reference: CJCSI 3150.25G, Joint Lessons Learned Program, 31 January 2018)
