Opportunity is missed by most people because it is dressed in overalls and looks like work. - Thomas Edison
I'm not sure how well any kind of quantitative goal would work honestly, just considering the variables involved (quantity/colors per shirt/setup time/business ebb and flow/etc). Not sure what you are having him do either (printing/screen prep/cleanup/etc). I would say, he should be keeping busy and improving without making too many mistakes, complaining, or taking excessive breaks. If he is doing that and your clients are happy, you should be happy.
You could try breaking areas down, because orders just vary too much. One 100 piece job with a one color print in 4 locations is nothing like 24 2 color prints on a light shirt in one location. So try one color prints; after it's set up, how many can he print in one hour? Don't have a job large enough for an hour, then time how long it takes to print say 24, let's say it's 15 minutes; then you know you/he could print 96 per hour. Then try the same thing with a 2 color print, and so on. Document the setup and breakdown separately, then add them together. To give you an idea of something to shoot for, everyone here (no rookies at all) can do at least 200 per hour, loading and unloading by themselves. Best of luck, you'll get it...Steve
Was one of our busiest weeks ever this past week. Counting last friday - this friday we have done almost 55,000 impressions over 65 different PO's. Today was 1 job, 11,500 shirts. Got it done in 1 day with 2 autos90% of the time it's me and 3 other guys in our shop...... Today I had some extra help boxing, staging, etc....... Most days I feel like we kick ass and we certainly have the last week but not all weeks are like this for us. Just in the last month we have had 5 orders each over 11,000 shirts each
