DevOps is not a new technology or a product.
It’s an approach or culture of software
development that seeks stability and
performance at the same time that it speeds
software deliveries to the business.

People Change
• There’s no right culture for
DevOps, but there are some
characteristics:
– Open communication
– Cross functional collaboration
– Goal alignment
– Respect and trust
• If your organization isn’t these
things, you have to build them

19. 19
Team Change - Cross-functional Team
• Share responsibilities
• Self sufficient
– They write it
– They test it
– They deploy it
