Today I’m opening a discussion about of 2 terms that come from the Lean lexicon: TAKT TIME, and ACTUAL TAKT TIME. Remember, “Lean” is the occidental word defining what it is basically the Toyota Production System, implemented in Japan in the 60’s, and that the rest of the world tried to embrace 20 years too late, and that trying to make it very, very short, it is based in the identification of the production wastes -jp. muda- and the processes to eliminate them. But we will talk about these terms here because they are very related to the production costs.
