The document outlines seven virtues that lean architects should uphold: 1) Know your stuff and use your brain rather than imagination, 2) Know your business and create suitable solutions, 3) Simplicity rules and simple solutions work better, 4) Communicate widely and show progress to stakeholders, 5) Be pragmatic and accept that you can't always have it your way, 6) Have a vision but keep it tangible, and 7) Focus on results and filtering out unnecessary information. The virtues are meant to guide architects to create practical and effective solutions.
