The Joint Operational Medicine Information Systems (JOMIS) is a program management office (PMO) within the Defense Healthcare Management Systems Program Executive Office. The JOMIS PMO is responsible for developing, deploying, sustaining, and modernizing operational medicine information technology systems and uses an agile methodology to develop and maintain a comprehensive portfolio of software applications. Together, these software applications allow JOMIS to provide interoperable medical information technology capabilities across the full range of miliary operations. The agile development methodology uses an iterative approach to break a project into smaller phases and emphasizes continuous collaboration and improvement across the lifecycle of the software application. JOMIS successfully leveraged the agile software development process by pairing software development sprints with successive demonstration, training, and testing events that allow the end-user community to engage with the application. One application in particular was trialed in numerous testing and demonstration events. The Battlefield Assisted Trauma Distributed Observation Kit-Joint (BATDOK-J™) software application was featured in a wide variety of testing and events, such as the Joint Operational Test, Army’s Soldier Touchpoint, Balikatan 2025, Bold Quest 2025, the Army’s Transforming in Contact persistent experimentation, and the Uniformed Services University of Health Sciences Operation Bushmaster. This wide variety of events allows end-users to engage with the applications, provide feedback which can guide development, and begin to plan how the software will be successfully implemented in real-world situations. JOMIS also included NATO allies in these events and demonstrations, which enables software development to reach across international borders. These efforts successfully demonstrated the utility of a health care delivery application developed using agile software development methodology. With the support of the Joint Services, JOMIS is prepared to deploy the BATDOK-J application along with a complimentary suite of health care delivery applications which will provide warfighters with technologies to make life-saving and critical mission decisions.
