Why your process improvement won't last six months

The improvement worked. Cycle time fell, errors dropped, and everyone agreed the new way was better. Six months later the team has drifted back to something close to the original process, with a few fresh workarounds layered on top.

Nobody owned the new way

Improvements survive when a specific person is accountable for the metric, sees it weekly, and has the authority to intervene when it moves. Without that, a process degrades at exactly the rate that staff turnover and edge cases introduce exceptions.

The exceptions were never designed for

Most reversion begins with a legitimate exception the new process could not handle. Someone invents a workaround. It works. It spreads. Design for the awkward fifteen per cent at the outset, even if the answer is simply an explicit escalation path.

• A named owner for every core process

• One leading indicator, reviewed weekly

• A documented route for genuine exceptions

• Onboarding that teaches the new way, not the old

• A quarterly check that the process still matches reality

Make it easier than the workaround

People do not follow a process because it is official. They follow it because it is the path of least resistance. If your improved process is slower for the person actually doing the work, it will lose — whatever the dashboard says.
