The 5 S’s of Kaizen: continuous improvement in your workplace

You’ve no doubt heard of kaizen, an Eastern philosophy based on continuous improvement. A method has been developed around this, based on the 5 S’s of kaizen. Would you like to find out what they are so you can apply them to your daily life? In this post, we’ll go through them one by one!

5 o'clock S for kaizen

The 5 S’s of Kaizen were developed by Japanese companies in the 20th century, and they set out the five key points that encapsulate an entire way of life and philosophy based on change towards improvement and productivity. This term is made up of two concepts: kai (change) and zen (goodness). Below, we explain what these five key principles consist of:

• Seiri (Sorting): refers to the importance of sorting and separating the necessary elements from the unnecessary ones. The aim is to eliminate everything that is not essential or a priority, in order to improve efficiency. In this step, clutter must be eliminated – whether it be physical items or thoughts, ideas or processes that get in the way.
• Seiton (Tidying): Once you have sorted everything, you need to organise each item – that is, assign it its own space, position and importance. In the case of physical items, everything should have its own designated place, which makes it easier to find them and access them quickly when needed.
• Seiso (Cleaning): This principle focuses on maintaining a clean and uncluttered environment. It involves regularly cleaning work areas, equipment and tools. Applied to the mental realm, it would be like freeing ourselves from thoughts that paralyse us or make us feel bad, thereby hindering our ability to work efficiently towards our goals. In this way, in the workplace, accidents can be prevented, the time spent searching for items is reduced, and staff morale is improved.
• Seiketsu (Standardisation): Here, standards and procedures are established to maintain the first three «S’s» (sort, set in order and shine). Standardisation helps to ensure that continuous improvement efforts are sustainable over time and become standard practice.
• Shitsuke (Discipline): The final «S» refers to discipline and self-discipline. It is vital that, first and foremost, we are disciplined and hold ourselves to high standards, so that everyone in the team takes responsibility for their tasks. Discipline involves staying focused on meeting the established standards and carrying out regular reviews to ensure they continue to be applied correctly.

What is the true origin of the Kaizen philosophy?

The Kaizen method has its roots in Japan and dates back to the the post-war period following the Second World War. During the 1950s, Japan found itself in a very unstable and weak economic situation; consequently, in order to rebuild the country and its industries, it was necessary to find new ways of improving efficiency and productivity in factories and businesses. Consequently, leading Japanese companies adopted and developed the Kaizen method as part of their corporate culture.

The development of Kaizen is mainly attributed to the Japanese engineer and consultant Masaaki Imai, who popularised the term from the 1980s onwards. However, as mentioned earlier, William Edwards Deming and Joseph M. Juran also contributed their insights to the definition of Kaizen.

Over time, this approach spread beyond the country’s borders and was eventually adopted by the world’s other industrial powers.

Nowadays, the Kaizen method is not only applied in the industrial sector; rather, continuous improvement is also being implemented through various methodologies in the field of education, in corporate environments, and even in the context of personal development.

The Kaizen method in business

The 5S methodology in the workplace is based on kaizen, or as it is known in Europe, lean manufacturing. However, its origins can be traced back to the assertion made by the statistician Edwards Deming, who argued that every process is variable, and that the less variable it is, the higher the quality of the result.

To adopt the Kaizen method, it is necessary to eliminate complacency, identify customer needs, monitor the competition and optimise time as much as possible. One pioneering company in applying this method to its production was Toyota, the multinational car manufacturer that managed to reduce the cost of its products without compromising on quality by eliminating superfluous processes, resources and materials. In other words, anything that was not essential to production was eliminated.

However, looking beyond the industry and focusing on the concept of corporate culture, the Kaizen method proposes that all employees should make progress both in their professional development and in achieving the company’s objectives. This is achieved by adhering to the following points:

1. Selecting targets small, measurable, short-term goals that will help bring us closer to our ultimate objective.
2. Building a strong team, consistent with and in line with the proposed objectives.
3. Listening to people’s views which come from all departments within the company, as they will provide very valuable information from various perspectives on the same issue.
4. Analysing the data of those we have identified as most significant for the objectives we aim to achieve. This will be done using tools such as: control charts, the Pareto principle, scatter plots, histograms and checklists
5. Drawing up a plan of countermeasures so that it can be carried out as soon as possible.
6. Monitoring and evaluating the results and presenting them graphically.
7. Recording the problems that have been solved so that the process of continuous improvement can be monitored.

We hope you’ve found the Kaizen method truly inspiring and that you’ll start applying it to every area of your life. If you’d like to discover more tips on professional and personal growth, be sure to follow the Educa.Pro blog closely – we look forward to seeing you there!
