2.5.4. Section 4: Final Recommendations. Same as the regular ICD with the addition of the “IT Box.” Discussion in this section should be tailored to the IS solution and focus on how the Sponsor intends to develop and deliver the required capabilities detailed above.

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

2.5.5.5. Affordability. When writing an ICD, the Sponsor should not have a predetermined capability solution in mind, nor the level of required detail to produce associated cost estimates. Additionally, multiple Services may develop capabilities based on a different sponsor's ICD and the initial Sponsor may not have insight into these development efforts. However, a constrained fiscal environment with competing demands for resources requires that Sponsors consider affordability in the development of an ICD.

2.5.5.5.1. The ICD should identify key factors that the Sponsor knows of, that may be, or may become, significant cost drivers for potential materiel solutions that may flow from the ICD. This information can help DoD focus S&T and risk reduction efforts, thereby potentially reducing the resources needed to satisfy joint military capabilities and eliminate or mitigate the associated gaps identified in the ICD.
