When I worked as a laboratory technician, I remember attending one of those Kaizen events. For the uninitiated, a Kaizen Event, also known as Kaizen Blitz, is a short-term project that implements Kaizen, a Japanese word that means a team-based approach in making process changes in small increments.
Improved workplace productivity stands out as the main goal of Kaizen. And one top company that consistently applies this is Gembutsu. 
Gembutsu is a company composed of lean manufacturing consultants. And not just consultants, they're Japanese trained to provide the top quality lean services aimed at teaching people how to make continuous improvement a habit. That said, Gembutsu's use of tools and philosophy of Toyota Production System a.k.a. lean manufacturing will help in eliminating waste in business processes, which is one of the best accomplishments that any company with a goal to grow should achieve.
Gembutsu conducts Kaizen events or Gembutsu Training Events, which are tailored for business decision-makers who are planning to reduce costs and improve efficiency. However, there's this worrisome situation that can happen if Kaizen is not taken the way it should be - getting kaizen-ed out of a job. Since labor is one of the types of waste that Kaizen events eliminate, reducing headcount can happen, which is one of the greatest fears of the workers who attend these events. However, business decision-makers are warned that the purpose of Kaizen might be defeated if this happens.
