2.5.1.3. Section 3: Capability Discussion. Same as the regular CDD with the exception of the following:

2.5.1.3.1. Provide a table that briefly describes the contribution this IS-CDD makes to the fulfillment of CR described in the applicable ICDs or analysis of the capability gaps as illustrated in Figure B-15.

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

2.5.3.1. The purpose of this Section is to identify the validated requirements and associated capability gaps addressed by the CDD, and to outline the results of related studies or analysis performed since validation of the requirements.

2.5.3.1.1. Narrative in the capability discussion Section, especially the discussion of dependencies, is to be consistent with DoDAF SV-8 generated during prior analysis, as modified for the scope and purpose of the CDD.

2.5.3.5. Additionally, if the CDD is not based on a validated JCIDS document, provide the CRs and associated capability gap information outlined for Section 3 of an ICD in addition to the content outlined in this section.
