So earlier we talked about Muda which was the waste related to non value added activities. 2
Then we talked but Mura, Mura was because of unbalanced work. 3
And this third type of waste is Muri ,Muri is also related to Mura the one which we learned earlier because 4
of unevenness of work. 5
Mura is the waste which is because of unreasonable stress on persnal machinery or equipment. 6
And why do you have unreasonable stress on people or machine because you have unbalanced work. 7
So if you have unbalanced work, if you dont have a clear instruction, if you dont have a clear planning, 8
if you dont have a well thought out of performance measures then Muri occures. Muri is something which 9
leads to stress in human beings and stress in the machine system. 10
So when it comes to people, Muri means that there is too much of mental tension, there is too much of 11
a physical burden. 12
And in terms of machinery Muri means expecting machines to do more than what this machine is capable 13
to do running this machine at about a hundred percent performance level. 14
That's Muri which of course in long term might lead to breakdowns. 15
So with this we have covered three broad categories of Waste- Muda, Mura and Muri. In Muda 16
we said that there are seven types of Wastes which are defined as TIMWOOD we will be going through the 17
details of each of those seven types of muda's in next seven slides.
