Welcome to the Throughput Academy

Learn about the Theory of Constraints
Teach others about TOC
Get results using TOC

Throughput Academy tutorials are developed by Draethen Solutions and contain the combined learning of over twenty years experience implementing TOC in a huge variety of different organisations across the globe - with stunning results.

We will help you understand the problems inherent in conventional 'MBA textbook' management approaches to operations management - manufacturing, services, supply chain, projects and complex multi-project environments - sales, marketing, management accounting, decision-making, and competitive strategy.

We will also teach you, in detail, the TOC alternative - not just what it is, but how you do it in practice and achieve measurable bottom-line results, as we have with our clients for over twenty years. Right down to the technical details of how successfully handle specific situations in different environments.

We hope to post a variety of tutorial videos on different aspects of TOC, some of which will be free-to-access and some subscribe-to-access. Follow us on social media to stay up to date with new releases.
