From Change To Mindsetchanges Testing efforts like cops writing traffic tickets Shift Left Test-first to build-in quality while coding Server operations like guards limiting access Self-service Server operations as enablers, trainers, and helpers People inspect code Automation People automate inspection Programs are hand-coded and static Code gen. Code generated from computer-readable requirements (Swagger, JHipster) Each specialist separately analyze own data Integrated reporting Detect trends & anomalies across versions & environments & initiatives People periodically reacting to lines on graphs Intelligent Alerts Predictive alerts from constant scans of all environments
