In this section you'll specify how the individual system will interoperate within the joint environment. This includes Net-Ready Interoperability, Physical Interoperability, and Joint Training Interoperability.

- Include information that may enhance innovation such as the use of a Modular Open Systems Approach (MOSA)* to support future incremental development. Make sure this is in-sync with Section 4 of your CDD as well as the PM's acquisition strategy. (*Note: For information on MOSA see DoDI 5000.85, Major Capability Acquisition, page 27.)
- If applicable, address intelligence interoperability requirements (see Annex G to Appendix G to Enclosure B, JCIDS Manual

Physical Interoperability. Describe the physical aspects of joint interoperability that may impact the capability solution. This description must be consistent with the OV-2 in describing resources flows to and from the proposed capability, and further described in the SV-1 to describe what enacts the OV-2 flow, now (as-is) or in the future.

- Describe any physical requirements (i.e., required landing space, runway length, etc.) that may impact the joint force.
- Describe any SoS or FoS considerations.

Net-Ready Interoperability.

- Discuss Net-Ready Interoperability as described in Annex A to Appendix G to Enclosure B, JCIDS Manual.
- The Net-Ready Performance Attribute table in Section 5 of your CDD presents the net-ready performance attributes and their associated metrics (Figure B-11, JCIDS Manual)
- Net-Ready threshold and objective performance values should be represented in numerical form whenever possible to preclude subjective interpretation.
- See Figure B-12, JCIDS Manual, for the three Net-Ready development steps, with attribute details, measures, and sample data sources.

Joint Training Technical Interoperability (JTTI).

- For systems with a mission solely focused on training, exercises, and/or mission rehearsal, specify how these systems will interoperate within the Joint Training Synthetic Environment (JTSE), including effects on joint training operations with allies and partners.
- State the intent to design these systems to JTSE standards and discuss technical approaches to ensure technical interoperability.
- JTSE standards are maintained in the DoD IT Standards Registry (DISR) (CAC required),
