Are you a recent business graduate or experienced professional searching for ways how to become a Lean Six Sigma trainer, What are the essential qualifications required to be so, and what is the minimum experience?

Lean Six Sigma is a business managerial approach that aims to improve the efficiency of a company by reducing any type of resource waste as well as malfunctions. Derived from 2 approaches, the Lean enterprise philosophy and Six Sigma methods, it essentially eliminates any type of time or resource waste without compromising on quality.

Coined by Motorola Quality Engineer Bill Smith, Six Sigma is a trained improvement method that aims to increase management, quality, and training within the organization while ensuring global competitiveness.

On the other hand, the lean thinking method was first introduced by Toyota to create more production with less human effort while requiring fewer inventories.

Modern businesses combine both these ideologies to reduce eight types of waste, and the acronym is DOWNTIME.

• D: Defect
• O: Overproduction
• W: Waiting
• N: non-utilized talent
• T: Transportation
• I: Inventory
• M: Motion

Lean aims at using various tools or methods to locate and eliminate any kind of waste, and Six Sigma refers to using any kind of strategy or plan to improve the manufacturing process.
