The fourth category of waste is Waiting time. 2
So operator number two has done his or her work. 3
Now 4
he or she is waiting for the first operator to finish the job so that this person can do work on that. 5
So waiting is another type of waste where the time gets wasted because the operation is not going in 6
sequence. 7
Something is happening in the previous operation which is leading to this particular operator waiting 8
for product or the input to come to this person. 9
So this is something which needs to be avoided that people don't need to wait for the previous operation 10
to be finished to do 11
their own work.
