Home > Practice Areas > Lean Assessment / World Class Certification


Since 1984, Technical Change Associates (TCA) has worked with forward-thinking organizations to enhance performance and accelerate growth. Our Extreme Lean™ assessment and certification process is just one more way we’re helping to build and strengthen some of the world’s best companies.

It all begins with assessment, where we numerically score the results of a rigorous examination and document areas of weakness or nonconformance. We then identify activities to address areas for improvement.

When applied frequently and consistently, this process can greatly accelerate your journey to Lean. The assessment and certification process determines the maturity level of your Lean implementation to accelerate future progress. And when your assessment scores reach an advanced level,
we will certify your company as a World Class Enterprise.

Assessing and Certifying Your Success

We evaluate 11 specific capabilities of the Lean/WCE:

Assessment Leads to Certification

An organization that attains a score of 2.7 on a scale of 3.0 is a mature Lean company that ranks with the best and earns certification. Displaying the Technical Change
Associates Extreme Lean™ certification plaque announces that your achievements are truly World Class. Companies that achieve this certification can rest assured they are meeting the highest criteria for a number of other prestigious awards.

Take the first step to achieving the performance, status, and recognition that you and your company deserve. Contact us today to get TCA’s Extreme Lean™ Certification program working for you.
