Kaizen, Lean and Six Sigma

The terms Kaizen, Lean and Six Sigma are often used interchangeably and, for many, have lost their individual identity. Businesses that fail to create value for their customers are deemed “wasteful." Sterling Development uses each Kaizen, Lean and Six Sigma to solve different challenges to eliminate "wasteful" practices, refine production and increase efficiency. 


Kaizen, meaning ‘never ending improvement by everyone in the organisation’ is a journey and not a destination. It helps to identify and solve problems associated with Muda (waste), Mura (inconsistency) and Muri (burden on people and strain on machines) that delivers big results from small changes.


Lean Manufacturing focuses on the elimination of waste to increase efficiency and streamline or remove non-value-adding stages in production. Six Sigma minimises defects as well as inconsistency (Mura) and helps to identify instances (using DMAIC or DMADV) where a process requires correcting or changing. 

Sterling Development believes that:

Good processes bring good results (improve efficiency and eliminate waste)


Good processes come from Brown Paper process mapping to standardise processes


Improve final product/service quality by finding and eliminating causes of defects or inconsistencies in the processes used


Eliminate ‘wastes’ to improve process speed and quality through reduction of the 8 wastes of process


Measure everything


Don’t assume, manage by facts


Act to contain and correct the root causes of problems


Work as a team by involving everybody all the time


If you are striving to become a Lean organisation, waste elimination is probably near the top of your list. At Sterling Development our lean practitioners use the 8 Wastes of Lean. Certain types of waste are easy to spot and fix while others can remain unnoticed. ​
