Information Exchange in Systems
Systems / Principles · Updated Apr 2026
A system's behaviour depends on how information flows through it.
The Idea
Parts of a system need to know what other parts are doing. The pattern, speed, and fidelity of that information exchange shapes the system more than any individual part does. Slow, distorted, or missing information creates dysfunction, regardless of how capable the parts are.
Why It Matters
- Many system failures are information failures, not component failures.
- Decisions depend on the information reaching the decider.
- Poor communication breaks healthy teams; great communication covers for weak ones.
How to Apply
- Map the flows. Who tells whom, how often, with what detail?
- Find the bottlenecks and distortions.
- Shorten feedback loops — faster signals change behaviour.
Examples
- Dashboards that surface real-time metrics to the team doing the work.
- Retros that feed learning back into planning.
- Open communication channels reducing the need for explicit coordination.
