Should "Waste" be included as Output in SIPOC Chart?

#1
The concept of SIPOC runs as businesses getting inputs from suppliers, adding value to it through internal processes and sending it as outputs to customers. Does "waste" generated in this internal process of adding value to the input, have a place on output, when creating a SIPOC chart?

Oversimplified example, If I create a SIPOC chart for making coffee, will coffee remains and dirty utensils be an output worth mentioning on the chart?

Not typically, since the coffee remains are not waste. Dirty utensils are not "transformed", either. Waste would be an proportion of the coffee which was undrinkable or in some way not consumed. Not what was planned, let's say.

Okay, makes sense. But that undrinkable part of the coffee, should it be mentioned on the SIPOC chart?

If its a bi-product and has a customer it makes sense to add to chart. If its just 'waste' then I would leave it out....

Yes, but as a KPI, i mean, you need to measure the efficiency of your process, and that's the way you can improve it. All your SIPOC diagrams need to have a KPI as an output. is like the turtle diagram.

a KPI isn't an "output" from a process.
Well, I mean it is directly related to an output, if your outputs are time, parts manufactured, shipments, you must relate an indicator to each output, that's where you control it, measuring the efficiency of your process and defining waste within it.
