How to combine the Toyota way and the Theory of Constraints to reach extraordinary results ?


By focusing Lean initiatives in the right places within the company the Theory Of Constraints leads to much faster improvements in performance. By identifying what limits sales, TOC enables organizations to renew with growth and avoid downsizing. You could call it focused Lean.

When Lean and Theory Of Constraints are combined, improvements are much faster and significant increases in sales are frequently observed. Lean drives out wastes and TOC identifies constraints on which to act to increase turnover. The combination of the two creates a virtuous circle whereby the company becomes continuously more effective by eliminating the added expenses, and simultaneously generates additional sales that can absorb the productivity improvements.

TOC + Lean EN

This webinar highlights two key assets of The Theory of Constraints: directing progress actions on the elements that degrade the overall performance of the system, making it possible to obtain significant gains very quickly, and having an approach that induces growth, thus avoiding the dreaded “Lean is a continuous layoff process” conflation. The Toyota Way is a model fueled by growth. And few industrialists understood this.
