The document discusses Capital One's transition from traditional software development practices to DevOps over the past 5 years. It describes how Capital One originally used mostly outsourced development, waterfall methodology, quarterly releases, and manual processes.

This success was shared with other teams, and the executive leaders approved a DevOps strategy to move operations and security closer to development.
