AI debugging: from hypothesis to verified fix
The latest models make investigation and repair more capable. The real speed gain comes from shortening the evidence loop without weakening the definition of done.
Field notes
Thinking in systems.
Concise observations on architecture, reliability, delivery, and the organisations around the software.
Architecture begins where reversal becomes expensive
Treat architectural significance as a gradient: spend design effort where reversal, evidence, and accumulated coupling make change costly.
Architecture is a sequence of decisions
The useful output of architecture work is not a diagram. It is a set of decisions a team can act on, challenge, test, and revisit.
Recovering a stalled delivery: fix the system of work first
A struggling programme usually has capable people trapped inside a broken decision and delivery system. Start there.
Availability is an organisational capability
Reliable systems come from architecture, operations, incentives, product decisions, and incident learning working as one system.
