Current Process
Wastes in Initial Coffee Making Process
➢
➢
Waste of overproduction: Excess of coffee grinds and water
Waste of waiting time: Excess water caused longer brewing time and the coffee machine
had to be moved to the edge of the counter in order to transfer coffee into the carafe
➢
➢
Waste of over processing: Used a carafe that was too large for the coffee machine
Waste of inventory: Pitcher wasn’t necessary to complete the process, use a reusable
coffee filter
➢
Waste of movement: Items were accessible from one single area, rather they were
scattered across the kitchen, start with all necessary items in one reachable place
➢
Waste from product defect: Consumer didn’t approve of the outcome
