In the 1990s, Toyota and Scania developed the Pulse-room concept, or Obeya as it is called in Japan. The pulse room is a solution to the problem with weak management control when organising work as projects. This problem was highlighted by several research programs during the 1980s. The effect of an Obeya was immediate for Toyota; in some few years they were able to develop the hybrid car Prius, and new brands as Lexus and Scion. It took their competitors decades to catch up.
