This is dead on. I think the biggest reason quality engineers turn unproductive is that they feel their efforts are wasted (pointless meetings, org policy requiring some inferior tooling&#x2F;platform&#x2F;language, etc.)<p>Those engineers are usually fairly vocal about obstacles. Managers should learn to interpret this signal, suss out the root cause (usually easy) and eliminate it (usually hard).<p>Twitter might actually be better served by promoting some set of the folks that landed on the cut list.
