When to retire a panel from the ops wall
Signs that a chart no longer earns its place: unread during alarms, contradictory colours, or metrics nobody can define in one sentence.
Ops walls accumulate panels the way storerooms accumulate spare brackets. Retirement is a discipline, not an insult to the person who requested the chart two years ago.
Watch the floor during a real alarm cluster. If nobody looks at a panel while coordinating crews, it is decoration. If two panels contradict each other on the same feeder, one must go or both must be rewritten.
Ask a supervisor to define the metric in one spoken sentence. Hesitation is a signal. Charts that require a five-minute legend do not belong beside the ticket queue.
Archive rather than delete when history matters for audits. A retired panel can live in a planning workbook while the wall stays legible.
Schedule a quarterly prune alongside threshold reviews. Small, regular removals hurt less than a sudden redesign after a failed inspection week.
