I'm currently studying Market Sizing type of cases and I have seen some websites recommend to segment using the bottlenecks, however I don't understand well what do they mean by this?
For example: When market sizing the revenues of your closest starbucks, you can segment it on # customers and average spend per customer. On the # customers side, they segment it by # of cashiers and # customers per cashier, they say this is the bottleneck, however I don't understand well what are they and how to find them.
I would appreciate if you could clarify it for me.
Thank you very much.
