Kaizen approach was originally introduced in the West by a well known Japanese author Masaaki Imai in his book known as Kaizen: The Key to Japan’s Competitive Success in the year 1986. The word ‘Kaizen’ implies constant progress. It has been derived from two Japanese words, “kai” which means ‘change’ or ‘to correct’ and “zen” means ‘good’. Now, Kaizen philosophy is recognized throughout the world as one of the long term competitive strategies of the organization.
Kaizen is basically a practice of continuous improvement in terms of quality, company culture, productivity, technology, processes leadership and safety. The system can involve all the employees from the upper level of management to the lower level staff like the cleaning crew. The improvement in an organization should be on a regular basis and the contribution should come from all the employees. The concept believes that large results can come from small changes gathered over time.
