About the webinar


Who says Theory Of Constraints (TOC) says constraint, or bottleneck. The whole challenge therefore lies in the identification of this resource before being able to apply the continuous improvement process of the TOC, the 5 Focusing Steps, in order to improve the performance of your organization.

For more than 15 years, we have seen that companies regularly are wrong about their constaint's location, and more and more often we find the bottleneck in a neglected place, a place no one seemed to consider: the quality control.

In this webinar, illustrated by many examples from a wide variety of different companies and sectors, Philip Marris, expert in the Theory of Constraints and Lean for more than 35 years, has shared his experience from several years of support for manufacturers in improving their productivity, increasing their throughput as well as reducing production lead times and improving the service rate:

- How did quality control become a bottleneck without anyone noticing?

- Why is it a very bad bottleneck?

- But how is this ultimately good news?

- How to debottleneck the quality control?

- In addition to the capacity aspect, which points of vigilance you should have

The end of the webinar has been dedicated to a Q&A session.
