4.3.17. Transition Process
Transition is the process applied to move any system element to the next level in the physical architecture. For the end-item system, it is the process to install and field the system to the user in the operational environment. The end-item system may need to be integrated with other systems in the operational environment honoring the defined external interfaces. In this case, the transition process needs to be performed in conjunction with the integration process and interface management process for a smooth transition.
Early planning for system transition reduces risk and supports smooth delivery and rapid acceptance by the system’s end user. Transition considerations should include, as appropriate, user and maintainer requirements, training, deployability, support tasks, support equipment, and packaging, handling, storage, and transportation (PHS&T). Part of the Transition process is ensuring that each site is properly prepared for the receipt, acceptance, and/or installation of the system.
The Transition process includes maintenance and supportability activities for the deployed system and its enabling system elements, as well as a process for reporting and resolving deficiencies. The OUSD(AT&L) memorandum, “Document Streamlining – Life-Cycle Sustainment Plan (LCSP)” requires that sustainment and support planning be documented in the LCSP, which is required for all Major Defense Acquisition Programs and reviewed prior to Milestones A, B, and C, as well as the Full-Rate Production Decision Review (FRP DR).
The Program Manager, Systems Engineer, and Product Support Manager oversee all transition plans and activities required to install or deploy the end-item system and enabling system elements to its operational environment. The Systems Engineer conducts In-Service Reviews (see DAG section 4.2.17. In-Service Review) and leads all engineering efforts to correct deficiencies found during transition. Program Managers should ensure all deliverables, particularly documentation (i.e. drawings, tech manuals, etc.), have been received from the contractor.
Transition activities vary based on life-cycle phase, program scale, and system complexity. The end-item system may need to be integrated with other systems in the operational environment based on the defined external interfaces. In this case, the Transition process is performed in conjunction with the Integration process and Interface Management process for a smooth transition.
