How can you determine the stability of modules in Sitecore Helix?

Determining the stability of modules in Sitecore Helix is primarily assessed by evaluating the number of incoming and outgoing dependencies. High stability is often associated with a lower number of dependencies; this indicates that a module is self-contained and less likely to be affected by changes in other modules. Conversely, a module with a high number of dependencies can become unstable if changes occur in any of the modules it relies on or that depend on it. This dependency analysis helps in understanding how interconnected different parts of the system are and serves as a guideline for managing and maintaining the overall system architecture effectively.

In contrast, while the number of bugs can provide some insight into a module's performance and reliability, it does not directly reflect the fundamental architectural stability. Similarly, the amount of uptime for a solution is more related to the operational reliability rather than the inherent stability of individual modules. Lastly, the frequency of change can indicate how actively a module is being developed or maintained, but it does not specifically measure stability; a frequently updated module might still have robust stability if its dependencies are well-managed.
