From the document: "Capabilities of the Department of Defense (DoD) are becoming increasingly connected and, as such, increasingly complex. Through concepts like the modular open systems approach and greater abstraction through commodity-like platforms providing compute and store, DoD continues to evolve toward an information enterprise where digital capabilities are the norm, and integration and security are more critical than ever. For the purposes of this guidance, a digital capability refers to a capability acquired through the DoD Adaptive Acquisition Framework that contains a component of information technology (IT) to include National Security Systems (NSS), networking, cybersecurity, electromagnetic spectrum, and/or positioning, navigation, and timing, pursuant to the relevant sections of Titles 10, 40, and 44 of United States Code (U.S.C.) and National Security Directive 42. Examples of capabilities that fall under this definition to include other terms that apply are provided in Section 3, Scope."
