Kaizen- Overview, Implementation and its Benefits

We live in a microcosm that is constantly evolving. With close-knit communication across the globe, our global market is getting stronger day by day. The competition among the businesses are rising continuously to stand out in the market by providing the best quality products and services at competitive prices. Hence, the companies must seek the best method to increase the speed, quality of their product and reduce the amount of waste.

Many companies are adopting the Lean methodology. Kaizen is one of the crucial pillars of Lean Methodology. It has a different set of definitions but the overall idea is to simply improve. Let us further dive into the details of Kaizen.

What is Kaizen?

The term Kaizen is derived from two Japanese words ‘Kai’ denoting ‘change’ and ‘Zen’ denoting ‘good’. Back in the 1980s, this Japanese Philosophy was first introduced by Toyota and since then it is adopted by many companies across the boundaries of the globe.

Kaizen is a statistical strategy that improves quality in every aspect of the business. It is a strategy where employees at all levels work ardently to achieve quality, efficiency, profitability, and create an empowered environment at their workplace. With the implementation of this strategy, workers are engaged in looking for opportunities for change and improvement. This is not a one-time event but a process that occurs every day.

How did Kaizen come into existence?

Kaizen began as a part of the “Toyota Production System”, a famous Japanese car manufacturing company. In the 1980s Toyota developed a business process to catch issues in the production at the very moment they occurred. If something did not align with the process, the entire production line would shut down to let the staff identify the solution to the problem.

The motive behind implementing the method was to never let the same problem occur again.

Over time it was observed that there was a visible improvement in the Toyota production system which empowered it to be known as the most efficient and reliable production company.

Since then Kaizen has been one of the respected instruments in Japan as well as an important pillar for them in becoming one the strongest industrialized countries in the world.

Why Implement Kaizen?

The Kaizen methodology is beneficial for diverse business models and operational philosophies.

At present, most businesses have the constant urge to upscale the quality and profit margin and reduce waste. If implemented properly, Kaizen methodology can be helpful beyond the scope of reducing waste and increasing quality. It can introduce positive results at overall business results. Let’s look at some crucial out of the many advantages of implementing Kaizen.
