This is a difficult process to measure. Are there mixers and shakers or by hand? Pre-op and post-op is not usually figured in, however everything should be cleaned and maintained. That adds to the minutes. Back to the beginning. Are the formulas in a notebook, or on the computer or both?
Either way this takes time. To me, this and so much more goes into a proper observation. I have visited shops where the ingredient people do their thing and then it is passed on to the mixers. I am all for automation, however this can be costly as well. So, if we have a shop where the ink person is on the phone instead of doing prep work well then chalk up that time.
As they say...….timing is everything. My approach is to minimize all this and have the ink staged on time. Multi tasking.
