Organization
Low trust culture High trust culture
Siloed teams Cross-functional teams
Lack of alignment Aligned around business goals
Processes
Lots of manual work Mostly automated work
Long cycle times Short cycle times
Poor visibility Fast feedback & insight
“Trying to effect process, people, technology and cultural changes across the entire application
portfolio, in a globally dispersed team and with a lot of associated technical debt, is an epic challenge.”
Jonathan Fletcher Enterprise Architect and Lead for Technology,
Platform and DevOps at Hiscox http://bit.ly/devopshiscox
Hiscox: Results
• Reduced cost per release on one application by 97%
• Reduced time per release by 89%• Reduced staff required to release by 75%• Automated testing reduced multiple man days
of effort down to an overnight hands-free process
Conflicting Incentives
Business Delivering value to customers
Dev teams Delivering new features
Ops teams Ensuring stability of systems
Quality teams
Ensuring quality of software releases
Everyone is responsible for quality and we’re all trying to
deliver the best solution for our customers.

Architectural CharacteristicsSignificant affect on IT performance• Does not require integrated testing
environment• Can deploy/release app
independently of other apps/services it depends on
• Custom software with microservices architecture
No affect on IT performance• Packaged commercial software /
COTS.• Systems of record / systems of
engagement• New, not-yet-deployed systems.• Software w/ embedded component that
runs on manufactured hardware device / user-installed component that runs on user’s machine

Peer-Reviewed Change Process
• Code can be contributed by anyone
• Code changes can be reviewed by anyone
• Code can be worked on as a team
Measuring ResultsThroughput• Deployment frequency• Change lead time (from dev’s laptop to
production)• Cycle timeStability / Reliability• Change fail rate• Mean time to recover• Availability / downtime
Deployment Pain
Tomorrow, ask your team two questions: • How painful are your deployments?• What’s causing the pain?
Diversify Your Team
