Public Announcement System
The challenge
What was in the way.
Public Announcement System needed hardware work delivered as one system rather than split across vendors — zoned public announcement hardware for live and scheduled audio across a site.

How we built it.
We restated the brief as constraints — power, latency, cost, compliance — and named the ones that conflicted. A working slice through the riskiest layer was signed off first, then built out in two-week increments with one demo each, reviewed against the same engineering standard across hardware and software.

One test matrix across hardware, firmware and interface — no gaps between layers.03Documented
Runbooks, monitoring and escalation handed over with the system.04Scaled
Grew with usage without re-architecture or a second rebuild.
