The cost of certification is also included in the course, making the total cost of the MSI program very reasonable. They even mail you a copy of your certificate. And your transcripts will always be available for future employers.
  • Flexible: All of the training is online and structured in flexible manner, allowing you take the course at your own pace. You can speed through it if you have the time or map it out over the course of a year. The course expires one year after purchase, giving you plenty of time to complete the course.

ExpertRating Six Sigma (Rank: #2)



  • Certification: ExpertRating offers certification with their course, making it a one-stop-shop when becoming certified in Six Sigma. You will have to pay for a hard copy, but only shipping and handling. Online transcripts are available at any time for proving your credentials. This makes the affordable pricing even better.
  • Combination Packages: Everything you need to take the course, study, and pass the exam is included in the up front price. There are no hidden fees. You won’t need to purchase additional study guides or textbooks. Everything is provided, even the exam. You also have thirty days from the time of purchase to decide if you want to continue the course or get a refund.
  • Project Scenarios: When learning Six Sigma methodologies, it’s crucial to learning how to implement them. Learning the philosophies and principles associated with them are time and money saving efficient ways of managing projects. But you must learn more than just the ideas behind Six Sigma. ExpertRating utilizes implementation to help achieve true learning through the use of several project scenarios. There’s no better way to ensure you’ve learned a core concept than to put it into practice.
  • Limited Number of Practice Questions: With only 200 practice questions ExpertRating lags behind its competitors. It’s as as a Six Sigma Certification course can be, which if you’re confident in the methodologies, then this might not be a bad thing. But if you need more, you’re better off with one of the other companies.

Bottom Line: One of the most convenient aspects of ExpertRating’s Six Sigma course is the all-in-one enrollment fee that covers every aspect of the process. Unfortunately, they have a disappointing lack of practice questions.


Simplilearn Six Sigma Course (Rank: #3)

Simplilearn Six Sigma Course


  • 64 Quizzes: With so much to cover in learning Six Sigma methodologies, it can be hard to self-assess your knowledge, but not with Simplilearn.

More Info About Six Sigma

Still not sure what makes Six Sigma certification a good idea? Check out these comparisons to learn more about what makes it different from other project management certifications:

Lean vs. Six Sigma

Both Lean and Six Sigma are methods of creating efficiency in the workplace, but there’s some debate over which one is more effective. That’s because the two of them have very different approaches to solving the problem, although they’re not incompatible in the same system.

Lean is the systematic process of eliminating waste and creating increased flow in a workplace’s production process. Doing so maximizes the value of your products while minimizing your company’s costs. In order to successfully utilize Lean, every tier in your organization needs to be on board. That’s because everyone needs to be able to make decisions about the allocation of resources and usage of new processes. As a result, Lean has far less of a focus on manufacturing than Six Sigma does.

Six Sigma, on the other hand, works almost entirely on a manufacturing level. That’s because its primary purpose is to use statistical analysis to reduce defects and variation in your production process. This is accomplished via 2 sets of 5 step approaches: DMAIC and DMADV.

  • DMAIC means Define, Measure, Analyze, Improve, and Control. Using this approach allows you to define the problem you want solved, find what’s causing it in your process, change it, and then maintain that change in the future.
  • DMADV is very similar to DMAIC; in fact, they share the same first 3 steps. DMADV stands for Define, Measure, Analyze, Design, and Verify. The difference here is that this process is used to create new tools in order to solve production problems.

PMP vs. Six Sigma

Both PMP and Six Sigma certifications are useful tools for a company’s success. However, the two of them focus on very different kinds of specialized strategies to get their work done. That’s because Project Management ensures that projects are done on time and within budget in order to match company goals, while Six Sigma identifies defects and variations in a process.

A Project Manager’s job is to boost the success rate of projects. They do so by setting a budget, keeping regular contact with company executives, and delegating team members into smaller segments of the task. If they can do all of these successfully, the project will be completed on time with a quality result.

On the other hand, Six Sigma experts need to know how to eliminate defects from a process. This is typically done by examining every phase of a process in extreme detail; only that can guarantee an increase in productivity. Otherwise, some issues might fall through the cracks and cause greater problems down the line.

The two certifications also have different licensing requirements:

  • Anyone with a PMP certification has proven that they can use all 42 project management tools at an expert level. They’ve proven themselves by passing the PMP exam that’s proctored by professionals from PMI.
  • By contrast, Six Sigma workers learn the certification at different levels that are designated by colored belts. These are the white, yellow, green, black, and master black belts. Only black belts or higher are allowed to lead Six Sigma projects.
