> The Science of Lean Software and DevOps: Building and Scaling High Performing Technology Organizations

---



Accelerate explores how software development teams using **Lean Software** and **DevOps** can measure their performance and the performance of software engineering teams impacts the overall performance of an organization.

> Note: DevOps is about integrating and automating software development (Dev) and IT operations (Ops), focusing on improving (and shortening) the systems development life cycle.
