Surveys conducted by John Kotter back in the 1980s suggested that more than 60 percent of all change initiatives fail. Further studies by McKinsey later validated that despite our increasing knowledge and experience, the statistics for failed changes remain intact. This means that the majority of lean initiatives that you may have introduced in the past have failed to deliver the expected or desired outcomes to the extent possible. This isn’t to say that there haven’t been improvements, but they simply have not been as substantial as originally expected.
