I need to obtain a finished product that product had to go through 3 process Process 1 Process 2 Process 3 Process 1 produce 50 product per hour Process 2 produce 50 product per hour But process 3 produce 40 product per hour... So the pace of our final product is 40 product per hour which is set by process 3... So that makes process 3 a constraint.. Process 3 is our drum Now what does a making process 3 our drum means? It means that it is producing 40 product per hour so we cant let it go down.. if there is some problem in process 1-2 and their output reduce ultimately the output of process 3 will reduce... How to avoid that? We place some already processed product from process 2 as an inventory to process 3.. this is called as Buffer What does buffer do..? When there is a reduce in input to process 3 the buffer provide an extra input so as to keep the process on its pace What does rope do? Rope is a signal to maintain the buffer level... Suppose i have 5 product in my buffer and when the buffer product reduce to 3 a mechanism will send the signal which will fill my buffer inventory back to 5 The same way we use Cards Kanban to ensure the inventory is upto the mark and the process didnt lack because of it
