Keynote: The Four Keys: Measuring Software Delivery
summary
Research shows software delivery performance is predictable using four metrics; the open source Four Keys project automatically ingests webhooks from GitHub/GitLab into BigQuery on Google Cloud and builds dashboards to track deployment frequency, lead time for changes, change failure rate and time to restore service. High performers are thousands of times faster on lead time and recovery, three times lower failure rate, and approach 10+ deploys/day. Case studies: Liberty Mutual reverses rising lead times; Ford Credit cuts deploys to every two days and reduces support calls.
