Study guides
Accelerated Expertise
Study how expertise develops. Work through the role of practice, feedback, and judgment, then apply the ideas to a skill you want to build.
Systems, Feedback & Change
Built on Donella Meadows’s Thinking in Systems, with three practical lessons from papers by John Sterman and his coauthors. Trace stocks, feedback and delays, then test a proposed change in a systems laboratory.
Business Thinkers
Ten modules, from reading a business and its cash through strategy, customers, pricing, operations, people, capital and change. Each case asks for a decision, adds new evidence, then asks you to revise it.
The Titans
Warren Buffett, Jeff Bezos, Howard Marks and Mark Leonard, followed year by year through their own letters and memos. Decide what you would have done, then compare it with what they did.
