Understanding Six Sigma Certification

PMP and Six Sigma certifications are both highly recognized and in-demand credentials in the business world. Six Sigma is a well-known project management certification. Here’s a deeper dive into this topic.

What is Six Sigma?

Six Sigma is a set of techniques and tools for process improvement. It was initially developed by Motorola in the 1980s and later popularized by General Electric. The primary goal of Six Sigma is to improve quality by identifying and removing the causes of defects and minimizing variability in manufacturing and business processes.

Six Sigma uses a data-driven approach and methodology for eliminating defects (driving toward six standard deviations between the mean and the nearest specification limit) in any process.

Key Focus Areas

This certification has provided many opportunities to people who use them. Here are the key areas to focus on:

  • Define
  • Measure
  • Analyze
  • Improve
  • Control

Levels of Six Sigma Certification

Six Sigma certifications are structured in a hierarchy of proficiency levels:

  • White Belt
  • Yellow Belt
  • Green Belt
  • Black Belt
  • Master Black Belt

Exam and Requirements

The requirements and exams for Six Sigma certification vary depending on the certifying organization. Generally, candidates must pass an exam and demonstrate hands-on proficiency through projects.

Green Belts typically require two weeks of training and the completion of a project. While Black Belts need about four weeks of training and multiple projects. It is useful for career development.

PMP vs Six Sigma: Key Differences

Both certification aims to enhance the skills and knowledge of professionals. However, there are some key differences between the two. Here are those.


PMP, focuses on the comprehensive management of a project from initiation to closing, emphasizing on-time and on-budget delivery. While Six Sigma concentrates on process improvement and quality management by reducing defects and variability.


PMP uses the PMBOK (Project Management Body of Knowledge) guide, which outlines best practices, tools, and techniques for project management across various domains. While Six Sigma uses the DMAIC (Define, Measure, Analyze, Improve, Control) methodology for process improvement and relies heavily on statistical analysis.

Industry Application

PMP is applicable across various industries including:

  • IT
  • construction
  • healthcare
  • finance
  • and more

It is versatile and can be used in any project-oriented environment. While Six Sigma is primarily used in manufacturing, but also applicable in service industries for improving operational processes.

Certification Levels

PMP offers a single certification level that demonstrates comprehensive project management expertise. Six Sigma provides multiple levels (White Belt, Yellow Belt, Green Belt, Black Belt, Master Black Belt) indicating varying degrees of expertise in process improvement.

Career Path

PMP is suitable for individuals looking to advance their careers as:

  • project managers
  • program managers
  • portfolio managers

Six Sigma is ideal for professionals aiming to specialize in:

  • quality management
  • process improvement
  • operational excellence
