Ownership
Every system, domain and operating responsibility should have a clear owner.
Operating principles
Build it so it can be operated.
Useful systems survive contact with real work. The group standard favours clear ownership, resilient architecture, measurable delivery and controlled change.
Resilience
Build for real operating conditions, graceful failure and recoverable change.
Clarity
Prefer understandable architecture, explicit boundaries and useful records over hidden complexity.
Interoperability
APIs and shared contracts should let each business remain distinct without becoming isolated.
Momentum
Ship useful increments, measure the result and keep improving the live system.
Stewardship
Treat brands, assets, data and infrastructure as things to improve and hand forward in better condition.
