Lean Six Sigma: Value Stream Mapping 

Yes exactly. It is simply observed. There is very little calculating involved when actually drawing it. The calculations (depending on what you are looking for), come after the drawing.

Hi there, Good question. To an extent, it falls into a grey area and is not blatant waste. That is true. But let me explain you why we chose to categorize it as waste even though it falls into a grey area. First of all, the communication with the cook does not add value for the customer. This is already the starting point. Are you willing to pay to have that communication with the cook? You might say it is necessary, but would you pay for it? Probably not. This by itself means that it is waste and this by itself means that we should do our best to minimize it, if not eliminate it. One company that has successfully recognized that and implemented a lean solution is McDonald's. They automated that communication by allowing you to bypass the communication with the cook by using their digital order pods. This way, the communication is more fluent. The cook does not have to wait for you and does not need to sacrifice time or write the order down or remember it since the order is automatically passed on to him digitally. No need to write it down, no need to communicate (communication with people is always inefficient, no matter how hard you try), no need to remember.

@@sixsigmaacademyamsterdam First of all, GREAT VIDEO!! so much easier to understand than a lot of other videos I've seen about VSM. Now, in regard to the McD example, how will it be interpreted the time the costumer takes to use the digital pod? What happens when costumers don't know how to use it and creates a lot of waiting for other costumers while you try to figure out how the pod works? A lot of "older" clientele is intimidated by technology, even with a simple ATM, so dealing with the huge screen, all the items on the menu and just the whole navigating through the screens can be quite frustrating. Also, from a costumer point of view, what happens with the waiting for your order to come out when the place is busy? that affects the takt time, doesn't it? I just realized these comments are from 5 years ago, so I hope someone gets to read them.

@@robertocucalon4676 Hi there, for sure you need to make that application so user friendly, so fail proof and poka yoke, that it will not create confusion.

Yes it is

whats 900?
