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

Become Test Driven...

Test Driven Development

Become Test Driven...

QA is not a team

QA is a cross-cutting concern

QA isn’t scalable

QA must leverage automation

Become Test Driven...

Do it in isolation

• Verify components in isolation (“unit”)

• Verify integrated components or subsystems (“functional”)

• End-to-end system tests (“system”)

on demand, low minutes

Do it with a crowd

• Performance

• User interaction analysis

• Traffic analysis

• A/B Testing / Feature Flags

• Operational unit tests

continuous, real-time

“A technical domain revolving around building and managing infrastructure programatically”

Infrastructure as code...

Can you automatically reconstruct the business from nothing but:

1. Source code repository

2. Application data backup

3. Bare metal/cloud resources

Adam Jacob / Opscode

Infrastructure as code...

“10th floor test”

Can you automatically restore your services if you:

1. Toss a random server out the window

2. Toss a random engineer out the window
