Ask a mounting room operator how long it takes to find a sleeve. They will say "a couple minutes." Stopwatch them through five changeovers and the actual number is usually 7–15 minutes per retrieval.
Why operators underestimate
Search time is fragmented. Two minutes here, four minutes there, plus a couple trips back to the prepress station to check the schedule. Each individual segment feels short. The aggregate is large.
The aggregate math
Take 10 minutes of average search time per changeover. Multiply by 8 changeovers per shift. Multiply by 2 shifts. Multiply by 250 working days. You get about 666 hours per year — roughly one-third of a full-time employee, or about 80 days of lost mounting time.
At a fully loaded labor cost of $30/hour, that is $20,000 per year per mounter. For a team of four, you are at $80,000 per year in pure search waste.
How to actually measure it
Pick a normal week. Have one of your mounters carry a clipboard or a phone timer. Record the start of each sleeve retrieval and the moment they have it in hand at the mounting station. Five days of data is enough to reveal the pattern.
The numbers will surprise you. They will also be the strongest piece of evidence you can put in front of a CFO when justifying a storage system.
What 60-second retrieval looks like
Defined locations, visual addressing, vertical orientation, and storage co-located with mounting stations. With these in place, retrieval drops from 10 minutes to under 90 seconds.
