Usability Testing as Schedule Insurance for Public Services

From a PMO seat, usability testing can look like a line item that threatens the timeline. I've learned to frame it the opposite way: it's the cheapest schedule insurance you can buy on a public-sector program. The expensive failures aren't the ones we catch in a test session — they're the ones that surface after launch, under public scrutiny, when the fix requires re-planning across teams. In govtech I run testing in tight, recurring rounds rather than one big event before release, and I test against the conditions that actually exist: older devices, slow connections, screen readers, users completing the core task under stress. Because accessibility is a legal requirement here, I treat assistive-technology testing as a gate, not a nice-to-have — failing it is a launch blocker, and a PMO needs to know that early, not in a pre-go-live panic. What I hand back is decision-ready: which issues block the core path, which touch optional depth, and which can wait. That lets a PMO sequence fixes against milestones instead of reacting to a pile of undifferentiated bugs. Predictability is the real deliverable.
