I have seen some great examples of "Lean" thinking on my recent consultancy trips in Russia. A great one for "Takt Time" , and meeting customer demand for airline passengers. Not only is the immigration both rigorous and efficient at Domodedovo Airport, but they have set a standard of 40 minutes from the time when the plane hits the tarmac, to the time you clear the airport with your luggage. On each of the last 4 occasions when I have been there, my luggage was on the carousel before I got to it, and the shuttles were quick. It would be interesting to do a VSM (Value Stream Map) based around saved business time. I would imagine it would run into Bil. RUB. It would be great to see the same approach at Heathrow.
