What this publication covers

This publication provides guidance for programs in the Operations and Support Phase including programs or systems utilizing O&M funding. Systems in the Operations and Support Phase are not required to retroactively meet information requirements identified in previous phases of the acquisition life cycle. These systems should continue to meet the requirements needed for continued operation to include modifications and maintenance activities. Sustainment activities utilizi ng investment funding should be categorized as either an AML or AML-Exempt program and report funding in accordance with this DAFI (see Chapter 11).
This instruction applies to the management of space and non-space acquisition programs to include weapons, weapons systems, national security systems, business systems, and all investment-funded activities (for the purpose of this publication referred to as programs throughout this document), in any phase of the life cycle. This instruction applies to acquisition programs using pathways in the adaptive acquisition framework (AAF) as defined in DoDI 5000.02 and shown in Figure 1.1 below. DAF acquisition programs begin by utilizing investment funding (i.e., research, development, test, and evaluation (RDT&E) or procurement) to satisfy a validated need.

Built from the publications' own citations, so it reflects what we have read.
