Lean Six Sigma: Certifications, Strategy and Methodology

When it comes to quality management, Six Sigma is the ultimate methodology and process management tool capable of ensuring the best results and reduced costs. Originally developed in 1986 and adopted primarily by manufacturing companies, Sig Sigma strategy and methodology is becoming increasingly popular with various organizations. Six Sigma process and quality control methodology prioritizes customer satisfaction, hence, it has been widely adopted by financial services, insurance, healthcare and other industries that rely on customer satisfaction.

When it comes to professional credentials, Six Sigma certification levels are:

  • Lean Six Sigma Black Belt
  • Lean Six Sigma Green Belt
  • Lean Six Sigma Master Black Belt
  • Lean Six Sigma Yellow Belt
  • Six Sigma Lean & DFSS

You may be surprised by the fact that Six Sigma certifications aren't provided by one certifying body – unlike most other professional certifications. You can get certified within your organization, and many employers invest thousands of dollars into training their staff according to Six Sigma methodology. Alternatively, you can achieve your Six Sigma credential (s) by learning independently and taking the exam from one of multiple independent providers. Either way, achieving a Six Sigma credential is linked with higher salaries, improved professional skills and long-term career prospects. Six Sigma certification holders usually average at 20% higher earnings than their counterparts with comparable skills and experience yet without these certifications.

Six Sigma Strategy

Six Sigma strategy and methodology are based on identifying and minimizing causes of defects in process results/outputs and minimizing variability in manufacturing, which leads to improved results. Six Sigma project teams have clear and quantified KPIs (Key Performance Indicators), including reduced costs, increased profit, reduced waste/pollution, increased customer satisfaction etc.

Six Sigma projects usually follow one of the two methodologies: Six Sigma DMAIC and Six Sigma DMADV. DMAIC is applied during projects aimed at improving an existing business process. Meanwhile, DMADV targets projects aimed at creating new product or process designs. Six Sigma certified professionals, especially Six Sigma Black Belt and Six Sigma Lean Black Belt are expected to be experts in both methodologies, since both of them are usually applied within the same organization.

Companies find value in Six Sigma strategy and certifications since they are an efficient tool for managing projects and delivering proven results, e.g. increased profit, reduced costs, shorter product cycle and soaring customer satisfaction.
