02Practice
Every system encodes a definition, written or not.
Governance is not one of five services sitting alongside the others. It is the discipline the other four are built on, which is why it is listed first and why every engagement produces the same three artefacts whatever it builds.
Governance first, then the other four
Sheet 03, the method in fullWhy the order matters
A pipeline built on a term nobody agreed is a faster way to disagree
Most engineering work assumes the definitions are settled. They rarely are. Building on an unsettled term does not surface the disagreement, it distributes it, and the next team inherits five systems that each encode a different reading. Koinon settles the term first, in writing, then builds.
The five
Each one answers the same test
- 02.AAI and Data GovernancePrivacy Act 1988, contested terms onlyEvery organisation already settles disagreements between its systems. Whoever is most senior in the room that day decides, and nothing is written down. This work replaces that person with a named owner, a written route, and a date.
- 02.BData EngineeringSource to report, not two transformations backNobody set out to break the chain. Each step was reasonable and none was recorded, so the trace stops at the first hop nobody can explain. These pipelines rebuild any figure they published from the inputs it had at the time.
- 02.CData VisualisationOne figure per quarter, and a stated denominatorEvery chart embeds a decision about what was counted and over what period, and almost no chart states it. These state it, and name the person accountable for the wording.
- 02.DSoftware EngineeringDated at the call, not reconstructed six months laterThe record is not for posterity. It is what keeps a system changeable, because a team that cannot tell deliberate behaviour from accident changes nothing.
- 02.EAgentic AI EngineeringAPRA CPS 230, every action replayableThe demonstration is the easy half. Whether the agent is still running a year later turns on whether anyone can account for a single action it took.
02Commission the work
Start with the disagreement you already know about.
Most engagements begin with a term two systems report differently, and a deadline that made it matter. Bring that one.
