What is a System of Systems? 

A System of Systems (SoS), or using microservices, is a complex structure in which multiple subsystems are integrated to create a larger, more comprehensive system. 


Each individual system within the SoS may have its own capabilities and purposes, but when combined, they work together to achieve a higher-level objective that would be impossible or inefficient for any single system to accomplish alone. 


Alternatively, you may have one system that was developed independently that another project or product may call on or use as a service in order to meet its requirements. 

This could be applicable to many projects, where one system is used by multiple projects as a service with many complex interactions. 

Versioning each subsystem / sub-project

In a System of Systems (SoS) approach, you can version one system independently of the overall project version. This is one of the key benefits of using a SoS approach, as it allows for greater flexibility and modularity in managing complex systems.


Each system within the SoS can have its own versioning scheme and release cycle, allowing for independent development, testing, and deployment. This means that updates or changes can be made to a specific system without necessarily affecting the versioning or release schedule of the overall project or other systems within the SoS.


However, it's important to maintain clear cross-project references to ensure that changes in one system do not negatively impact others. This can be managed through careful configuration management, documentation, and communication between teams using the Ketryx platform. 


By versioning systems independently, you can achieve more efficient development processes, quicker response to changes or issues, and better overall system maintainability. 


Augmented Traceability

Within an SoS, you may view the entire system project within the Requirement Traceability Matrix module, as well as in the subsystem project. Within the subsystem project, each component can be designed to meet its own requirements and teams can focus on the feature or product they are trying to implement rather than having to worry about a large traceability matrix that may be too comprehensive for one team to understand. 

From the system project perspective, a comprehensive visibility helps in understanding how changes in one system affects others, facilitating better understanding of possible integration risks when performing a deployment. By understanding the interactions between systems, it's easier to predict how the issues in one system might cascade or be mitigated by others.
