What are the three pillars of Kaizen?

Kaizen or continuous improvement is the daily practice of creating small changes using low-cost common-sense solutions.  Kaizen’s pillars or major activities are 5S, standardization, and waste elimination.

Where there is no standard, there can be no improvement.  For these reasons, standards are the basis for both maintenance and improvement

Housekeeping and 5S are basic activities for any continuous improvement effort.  Employees acquire self-discipline by practicing 5S daily.  Without discipline, it is impossible to sustain a continuous improvement culture.  The 5S purpose is to create a visual workplace.  The objective is to make problems visible, which is quite uncomfortable.  It is normal to try to hide problems to avoid undesired questions from the boss or dealing with them.  5S and visual management make the out-of-standard situation easy to recognize, and employees can easily correct it.

When we fail to achieve the expected results, it is because the process fails.  Many times, it fails because there is no standard.  Each individual has a way to do things.  Standard work is the safest, highest quality, and most efficient way to execute a particular task.  Standardization is the practice of setting, communicating, following, and improving standards and standard work.  The best way to achieve consistent results and minimize mistakes is to follow the standard work.  

To improve the results, we have to improve the process.  But we need to have standards in place before we try to improve it.  That is why standardization is one of the earlier steps on the lean journey.  Visual management is a way to standardize, it helps to recognize defects, inventory, waiting times, and other types of waste.  Waste elimination is a cost-effective way to improve processes and reduce operating costs.

The first steps on the lean journey are to stabilize the process, create standards, and visual management.  Process stabilization is achieved by practicing 5S and waste identification.  Standards produce a clear image of the desired condition.  You cannot fix what you don’t see. By making conditions out of standard visible, 5S, standards, and waste elimination are the pillars of kaizen or continuous improvement.

What is Kaizen? What is a Kaizen Event?

Continuous improvement (CI) or Kaizen is the daily practice of creating small changes using low-cost common-sense solutions.  In my post, Take Baby Steps for Continuous Improvement, there is a little history of how Kaizen was born.  Continuous improvement involves everyone in the organization, improving processes everywhere, every day.   

Since the goal of lean is to deliver to the customer the highest quality, at the shortest lead time, at the lowest possible cost, kaizen focus is quality, cost, and delivery.  Kaizen’s major activities are 5S, standardization, and waste elimination.  Daily execution of these three activities drives incremental improvement that brings dramatic results over time.

Daily CI is important to tackle small problems before they become big ones.  The inspiration for daily kaizen comes from observation of frequent deviations from the standard, or ideas to improve the process.  However, sometimes we have challenges that require a more methodical approach.  When that happens, a Kaizen event comes to the rescue.  Recurrent problems that affect productivity or KPI performance are a good candidate for an event.  

A CI or Kaizen event is focused on one problem or improvement idea at a time.  The goal is to accomplish dramatic improvements in 2-7 days period.  These are rapid events, short, and based on common-sense solutions with very low or no-cost at all.  The understanding of the problem, and kaizen planning are critical for success.  It is also important to standardize the way of performing kaizen, everybody should follow the same steps and document the execution of those steps in the same way.  A good method to ensure the problem-solving activity is standardize is using PDCA.

When it is done correctly, kaizen not only improve quality, cost, and delivery.  It also helps the heart of the lean system, the people.  It does so by eliminating safety hazards, simplifying processes, and teaching people how to identify opportunities, and improve their processes.  In my next post, I will discuss the general steps to perform a kaizen event.
