Software configuration principles are well supported by many tools which allow teams to easily handle branches of the same product. We can’t say the same for other aspects of the configuration management, like requirements and documentation and often teams shall create custom and “manual” rules to maintain the identification and traceability of the different branches of the same product.
In this Open Space I would like to hear people's experience on this and to discuss the best tradeoff between using custom rules and setting up tools (if any).
