It can be done!
When I started here in December, I found 1 flowchart for ALL of our products. We have 3 basic products (1 in packaged in different size containers, but the process is the same) I don't know who initially designed the flow chart, but it was difficult to follow.
What I did was redesign it, color coded each CCP type (biological, physical, & chemical) then make a key for each product.
Since each step was numbers, the key lists the numbers in order for each different product.
For example, the process for all products is the same steps 1 - 10, the product A is 11,12,16,18,23,24,25,26,30,31,32
product B is 11,13,16,18,25,26,31,32, etc.
I completed this the day before our recent USDC audit, and our auditor LOVED it. He said he was mad that he hadn't thought of it before, and was going to suggest it to other companies.
