Kaizen is all about making a continuous improvement. At a glance, it seems the definition could really easy to catch and understandable. Lean and Quality is apart of Kaizen and both can be sustain if the culture of Kaizen is inside the organization. In plain words, whether it is for a person, a group of people, an organization, or a global company, achieving high quality with low cost, increasing delivery capability ( response and speed ), and gaining the right level of flexibility ( in terms of variety and volume ) together with an increase of productivity, Kaizen is the answer. It is the root that could make Lean and Quality living in the system.
In this post, I would like to point out that understanding Kaizen philosophy will help us to get started with Lean and/or Quality. However, as experts have warned us against all the too much simplification of Lean and/or Quality, the danger of viewing Lean and/or Quality by neglecting people’s interest and dynamic can lead to catastrophic result. We, both beginners or experts tend sometimes to focus on technical stuff. In Lean Management, this disease is called concentrating only to the methods and not the philosophy. In Quality, this is called the disease of dealing with quality as a product/engineered product quality only and not dealing with the whole quality as perceive by the customer.
This tells us that in Lean as well as in Quality, the involvement of Human side adds value to the success of it’s movement. Practitioners in Lean have clearly stressed out that culture of providing customers with value by means of eliminating waste has to be begin by a cultural change. On the other side in Quality movement, it is also have been said that Quality engineering is not a complete Quality, and the Culture of Quality First for customers come with the involvement of workers. Both have point out the importance of workers and not just methods or tools or engineering calculation. Thus, it is safe to say that Kaizen needs to take care both Social and Technical perspective for it to success. Both methods and human is technical and social that forms a sociotechnical systems which refers to the interrelatedness of social and technical aspects of an organization. Thus, in my opinion it is important to think in terms of sociotechnical systems when we want to move forward with Lean and/or Quality.
