Value Stream Mapping is a pen and paper tool that highlights bottlenecks in a matter of hours and raises awareness of what difficulties other teams face @manupaisable | manuelpais.net 26
Practices for boring releases •Automated build (and unit tests) •Provision prod replica in pipeline •Automated acceptance tests (BDD) •No “invisible” activities •One source of truth •One path to production @manupaisable | manuelpais.net 38

Scalable CI/CD Infrastructure •Solved problem in cloud systems •Starts with infrastructure-as-code •Agent farm (auto scaling if possible) •Pipelines need to evolve as number of teams grows @manupaisable | manuelpais.net 54
Flow efficiency = “teams who aren’t paying attention to this concept generally have flow efficiencies around the 15% mark - that means that work normally spends 85% of its lifecycle waiting on something.” http://leankanban.com/flow-efficiency-a-great-metric-you-probably-arent-using @manupaisable | manuelpais.net 57

How resilient delivery looks like •Tooling and configuration changes do not impact regular delivery •Gracefully handles peak load of pipeline runs •Issues with underlying infra/tools handled swiftly, rollback if needed •Disaster recovery at a click of a button @manupaisable | manuelpais.net 81

Practices for resiliency (1/3) •Pipeline infrastructure-as-code •Pipeline configuration-as-code •Build and release from zero to live @manupaisable | manuelpais.net 85
