If you’re thinking about your people taking the ISO18404:2015 Lean6 Yellow Belt Certificate, why not go for the added qualification of an Improvement Technician Apprenticeship and get a minimum of 95% of the training funded!!

The apprenticeship will take 12-14 months to complete and be followed by an independent assessment that will review if they truly are practitioners and can change your business from the inside out.

We talk about making people as miserable as possible, but for the right reasons. We mean we want to test the character of the learner. We want them to apply this new learning to transform your business.
