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.
