A “ready for review” tag looks like progress, but it often masks a hidden queue that no one owns. The tag tells the team the work is finished, yet the next gate—usually a legal or compliance check—has no explicit owner, so the item languishes while engineers assume the gate will move on its own. Over time, the backlog grows invisible because the dashboard only shows “in‑progress” items, not the ones stuck behind the silent gate.

In one well‑known outdoor apparel company, a new line of recycled jackets sat in that exact state: designers celebrated the hand‑off, but the compliance team, lacking a clear mandate, never prioritized the sign‑off, and the launch slipped past the seasonal window. The result was a missed market opportunity and a morale dip among the designers who felt their work vanished into a black hole. What looks like a smooth hand‑off is actually a coordination debt that compounds each cycle.

The only way to surface it is to make the gate’s responsibility explicit and to track its dwell time as a first‑class metric.
