You need to determine how much time of QA is required per changeover. Then take the average number of changeovers per week and apply it to your daily production. Unless you have more QA staff on certain days than others it doesn't really help you to assess if more changeovers are on a particular day, or days, of the week.
For us, we vary on our changeovers each day and there really isn't anything set. So I just took the total average changeovers per week and spread it out to each day. I think it was about 30 changeovers a week over 7 days for about 4.5 changeovers per day.
Probably easier if I just show you my spreadsheet I used for my last two facilities. See attached.
Thanks, this helps a lot. Question - how or did you factor in the production schedule. We produce a lot of different but similar products each day. Running 20 or more products on different lines isn't uncommon where I work. I want to capture this since somehow.
