Cummins Inc. designs, manufactures, sells, and services diesel engines and related technology around the world. Cummins serves its customers through a network of 500 distributors and more than 5,200 dealer locations in over 190 countries and territories.
Cummins incorporates quality in everything they do, by using Six Sigma to continuously improve their products and services. And because Cummins sees no barriers to where and how Six Sigma can be applied, they have a large and extremely diverse list of improvements. The company has completed over 12,000 projects, saved over $2 billion, and trained more than 2,700 employees in Six Sigma techniques, including statistical analysis.
But using Six Sigma throughout the entire organization posed a challenge to the company’s Six Sigma training program. Because Cummins employs people with a wide array of skills and backgrounds, participants entered training sessions with a diverse range of statistical knowledge and experience. That made instruction difficult.
"Not everyone who becomes a Master Black Belt is a mathematician," observes K. Megan Henry, director of Six Sigma at Cummins.
That’s where Quality Trainer by Minitab comes in. Quality Trainer is an e-learning course that teaches Green Belts, Black Belts and other quality professionals the statistics they need to apply when improving quality and processes. It covers all the main methods used when implementing a Six Sigma project and includes instruction on how to apply them using Minitab Statistical Software.
When Henry evaluated Quality Trainer, she realized she had found a solution to some of the company’s challenges. "Quality Trainer completely aligned with our training needs," she says. "It teaches the basic statistics and Minitab techniques we need, without duplicating what we covered in our own training."
Quality Trainer helps people learn complex statistical methods quickly, with animated lessons that bring them to life. Users then practice the concepts they learn by working through real-world scenarios. At the end of each lesson, learners can test their knowledge with quizzes, understand why their answers are correct or incorrect, and, if necessary, learn which sections to review to fully master the material.
Best of all, when combined with Cummins’ license for Minitab Statistical Software, Quality Trainer was extremely affordable. Cummins soon secured an enterprise-wide license for Quality Trainer. "It’s almost unbelievably economical," Henry says. "We consider our enterprise license a real bargain."
Cummins has integrated Quality Trainer into the company’s Six Sigma training. "Now trainees are required to do the relevant modules before they come to class," Henry explains. "This gives the entire class a consistent starting point. Even participants with backgrounds as diverse as human resources and mechanical engineering are talking the same language!"
Henry says trainees have responded very positively. "Quality Trainer is easy to use, and the explanations are very clear and easy to understand," Henry says.
And because it’s available online any time, learning opportunities can be worked into even the busiest schedules. "At Cummins we believe in learning done on the job, and Trainer is so flexible it lets people learn at a schedule and pace that meets their own," Henry says. "It’s easy to use Trainer for a bit, take care of other responsibilities, then come back and pick up where you left off."
