I'd agree, I had the same thing , but once I got it in line, I make it a priority to keep it up, that's one thing that doesn't get pushed aside.
Once it's set up and running it's easy, it's just a lot of work to get to that point. I use a simple excel spread sheet, and at the beginning of each month I highlight who's up in that month, when that day comes around, I check their welds, fill out a sheet for the files cross him off the list, update the spreadsheet in the computer and do it all over at the beginning of each month.
