Six Sigma Courses & Certifications Online

Six Sigma certifications are a benchmark of expertise in the operational side of an organisation. They are especially useful in quality management and business process improvement roles. 

Ever since Motorola came up with Six Sigma as a methodology in the 1980s, its principles, such as DMAIC and DMADV are still in use across various sectors. The framework also aligns with the Lean management approach, and there are Lean Six Sigma certifications too. 

Six Sigma certified professionals today are in demand across healthcare, education, information technology, marketing, and other sectors. These project-based certifications add good weight to the resumes of those in the lower and mid-level management.

So, considering that you are from these working backgrounds (or maybe even a fresher), we show you where to acquire some quality training for Six Sigma certifications online. And how they will help you at any stage in your career.
