How will the Lean Six Sigma Green Belt course benefit me?

Lean Six Sigma is a great method used to increase productivity, decreasing costs, and improving customer value.

Lean is a method used to increase customer value and decrease wastage. Six Sigma is a method used to reduce processes through a set project approach. When both these methodologies are combined, they can reduce your costs, increase customer value, and improve your employee’s morale.

Lean Six Sigma is ISO 18404:2015 accredited. Being qualified in this standard will vastly improve your employability as you will show managers you can meet the highest standard available in Lean Six Sigma. Many employers in Project Management are always looking for certified project managers knowledgeable in Lean Six Sigma because of their superior problem-solving techniques used for improving business efficiency and saving costs.
