The major-incident bridge closed yesterday with a clean timeline, a polite &ldquo;thanks everyone&rdquo; and a promise that root cause would follow. Today the same symptom is back, under a different ticket number but in the same category, reported by the same annoyed colleague who has already told the story once.</p> <p>Your queue looks busy in the right way. Your problem record looks complete in the wrong way. There&rsquo;s a five-whys slide, a parking-lot action reading &ldquo;engage vendor&rdquo;, and nobody has an owner and a date for when this failure stops happening on Monday mornings.</p>
