Quota system (or a queuing system) is like juggling your days work to minimize any downtimes, get as many patients in and out in the shortest amount of time, understanding when you have downtime with a given patient and how that downtime can be reallocated to other patients waiting. It gets more complex as you increase the number of patients. Lets use a simple example.
I have 3 ops patients / 4 hygiene in hour 1, I have another 3 ops patients/7 hygiene in hour 2. Your limitation is your rooms and patients. If 2 of those ops patients are fills, 1 is an RCTBUCrn, I need to determine the sequence of numbing. Numbing will first go to procedure of priority, the rctbucrn. The reason is that you need to prep the crown first to start the crown fabrication process because that takes longer. The next 2 to numb are the fills. So when you numb all 3, you prep the crown, then take your impression or digital impression. Move to fills, and if no hygiene are ready, finish your last fills for the hour, and if no one is ready for hygiene checks yet, finish your RCT + crown cementation. If in any of those gaps, those hygiene checks are ready and you can squeeze them in, do them, if not, keep knocking out the ops. You have to always be aware of your schedule and any curveballs. You also have to be aware of any room shortages (such as, do I need an op room, do I need hygiene rooms?) My operating assumption is that I need the first hour hygiene out within the first hour. Then the fun piles in. You got your second wave coming. If you're not done with your ops procedures, you need to wrap it up, and get ready to incorporate it into a queue. If, for example, you didn't finish the RCT yet, but the crown is done, then you go numb the next 3 ops patients, they fall 2nd, 3rd, and 4th in line, looking at the same logical sequence as the first hour. Then push hygiene when you can. Repeat every hour until done. Hopefully this makes some sense.
