Alidade
Lay a straight edge across what you know.
Alidade is a measurement workspace for review queues. Every claim here is a line you can move: put one end on a record count, the other on minutes, and read the hours where it crosses the middle scale.
Start with your queue1,800 records at 4.5 minutes each cost 135 reviewer-hours a day: about 21 analysts at 6.5 productive hours each.
Move either end of the line: drag the magenta dots, or focus one and use the arrow keys. The ring on the middle scale is the answer, and you can drag it to solve for the right-hand scale instead.
How many are wrong enough to look at?
Most records are fine, and a rate of four in ten thousand sounds like nothing. Lay it across the count and see how many a person still has to open.
42,188 records at 0.04% off the ruling leave 17 worth a person. The datum line marks those and nothing else.
Every scale here is logarithmic, so equal steps mean equal ratios. That is why a single straight line can multiply two numbers and land on the product.
How many are open right now?
Arrivals per hour and minutes to resolve fix the size of the open queue, on any desk. That is Little's law, ruled onto three scales.
40 records an hour, resolved in 11 minutes each, keep 7.3 open at any moment. Cut either number and the queue shrinks by the same share.
Same line, new question. Hold the left end where it is and drag the ring on the middle scale to ask what resolve time keeps the queue at ten.
Bring one queue.
Alidade rules it, marks the one record in play and leaves every other record quiet.
