  24. PRINCIPLES OF FLOW • Make our work visible • Limit

    work in process • Reduce batch sizes • Continually identify and elevate constraints • Eliminate hardships and waste in the value stream
  25. TECHNICAL PRACTICES OF FLOW • Create the foundations of our

    deployment pipeline • Enable fast and reliable automated testing • Enable and practice continuous integration • Automate and enable low-risk releases • Architect for low-risk releases
  26. 2 Feedback

  27. PRINCIPLES OF FEEDBACK • Working safely with complex systems •

    See problems as they occur • Swarm and solve problems to build new knowledge • Keep pushing quality closer to the source • Enable optimizing for downstream work centers
  28. TECHNICAL PRACTICES OF FEEDBACK • Telemetry on all the things

    • Telemetry analysis • Alerting • Push data collection to the left • Build results • Static code analysis • Code security analysis • Testing results
  29. 3 Continuous Learning & Experimentation

  30. PRINCIPLES OF CONTINUOUS LEARNING & EXPERIMENTATION • Enable organizational learning

    and quality culture • Institutionalize the improvement of daily work • Transform local discoveries into global improvements • Inject resilience patterns into our daily work • Leaders reinforce a learning culture
  31. TECHNICAL PRACTICES OF CONTINUOUS LEARNING & EXPERIMENTATION • Lessons Learned

    meetings close to issue date • Culture of quality, testing, & monitoring • Identify and refine failure signals • Inject production failures to enable resilience and learning
