No, this analogy would make more sense if it was a matter of recording a large number of interactions between customers and tellers to ensure that the window isn't interfering with their interactions. Is the window the right size? Can the customer and teller hear each other through it? Is that little hole at the bottom large enough to let through the things they need to physically exchange? If you deploy the windows and then never gather any telemetry you have no idea whether it's working well or if it could be improved.
