2.5.4.1. Describe governance process for interfaces and data for the program to include any enterprise architectures, standards, software factories, or pipelines. Outline the major systems, services, and networks the software solution must be interoperable with. Describe how interfaces (internal and external) will be identified and design patterns to be used (API, proxy, etc.).

2.5.4.2. Describe the ways data will be handled in the system and plans to be used internally and if it will be accessible externally by other systems or users. Details of specific interfaces and a comprehensive list of all the interfaces will be identified in separate documents, models, architectures, and/or systems. As the SW-ICD is intended to be a high-level overarching document, address the key known elements, and update periodically as systems and networks are added, changed, and/or retired.

2.5.4.3. Reference any Digital Engineering strategy, frameworks, or models to describe how these design details will be capture and formats used to communicate both internally and externally, such as through model-based systems engineering or other methods.

2.5.4.4. Summarize how the software performance will support the Net Ready Key Performance Parameter (Figure B-6). This table should focus only on the performance attributes within the scope of the software capabilities defined in this document. It should reference other systems or documents that capture the broader network or weapon system Net-Ready performance attributes.
