26. Get Agile...
• Incremental, iterative and collaborative,
rather than distinct stages
• More frequent delivery of smaller, valuable
increments
• Building quality in, not adding it at the end
• Goal of potentially shippable at every
iteration
• Active user involvement (or customer proxy)
• Agile teams must be empowered and self-
motivating

Do it in isolation Do it with a crowd
• Verify components in • Performance
isolation (“unit”)
• User interaction analysis
• Verify integrated
components or subsystems • Traffic analysis
(“functional”) • A/B Testing / Feature Flags
• End-to-end system tests • Operational unit tests
(“system”)
