Understand
The workflow, existing system, constraints and people responsible for running it.
Build the important parts properly.
Architecture, operational software and systems that connect observations to decisions.
Architecture that holds together
Make the important decisions explicit before complexity makes them expensive.
Software people can operate
Connected workflows, clear permissions and tools that make exceptions manageable.
From observation to evidence
Systems that connect physical events, local processing and records someone can inspect.
Start with the part that matters most.
Define
The behavior to build, the tradeoffs to make and the evidence that will establish it works.
Build & verify
Implement a bounded piece, inspect the experience and exercise the important failure cases.
Hand over
The decisions, code, operational knowledge and clear ownership needed for what comes next.
