create progressively more resilient systems with higher degrees of assurance 3. Ch. 20 – Convert Local Discoveries into Global Improvements a. USE CHAT ROOMS AND CHAT BOTS TO AUTOMATE AND CAPTURE ORGANIZATIONAL FOR OUR ENTIRE ORGANIZATION i. Firm-wide shared source code repository is powerful way to share local discoveries to the entire organization 1. Configuration standards for libraries, infrastructure

Way into practice include never passing a known defect to downstream work centers, never allowing local optimization to create global degradation, always seeking to increase flow, and always seeking to

from our successes and failures, identifying which ideas don’t work and reinforcing those that do3. local learnings are rapidly turned into global improvements, so that new techniques and practices can be
