If you landed here you probably followed a link for either the Thinking Leader's Toolkit or Engineer Your System, two systems thinking courses offered by Joel Tosi and Elisabeth Hendrickson.

Those courses have evolved into our new book, Signals & Levers, coming out from IT Revolution on September 22, 2026.

In the lead up to the book publication we're working on our courses once again. We plan to offer instructor-led public courses based on the book through Maven and have started offering Lightning Lessons there in preparation. We also offer our systems thinking courses privately, either onsite or virtually.

We hope to see you soon! In the meantime you can find our book launch website here, and please sign up for our mail list for the latest news about the book launch, our appearances, and our public courses.

Many thanks for being part of the journey!

Elisabeth and Joel
