2.5.1.1. Section 1: Operational Context. No change from a regular CDD to the operational context section in the IS-CDD.

For reference or comparison, below is what the JCIDS Manual says for the CDD 2021 itself:

2.5.1.1.1. The narrative in the operational context section is to be consistent with DoDAF OVs generated during prior analysis, as modified for the scope and purpose of the CDD, including the DoDAF OV-1, OV-2, OV-4, and OV-5a. In cases where these DoDAF OVs are not available for updating, they shall be generated to support the CDD.

2.5.1.1.2 Provide the DoDAF OV-1 in this section. If applicable, include intelligence system connectivity and interoperability in the DoDAF OV-1. Do not include any other DoDAF views in this section unless specifically needed for illustration purposes for the CDD.
