DevOps
It is a mindset, a culture and a set of technical practices. DevOps represents a change in IT culture, focusing on rapid IT service delivery through the adoption of agile, lean practices.
The goal of DevOps is to improve collaboration between Development and IT Operations by developing and automating a continuous delivery pipeline. It provides communication, integration, automation and close cooperation among all the people needed to plan, develop, test, deploy, release and maintain a solution.
The “development team” is measured on the business value they deliver to the end users, while “IT service management” is measured on the health and stability of the production environment.
When each group has seemingly opposing business objectives, delivery inefficiency and organizational friction may rule the day, but DevOps ends the silo approach, providing an enterprise with the ability to develop and release small batches of functionality to the business or customer in a flow process called the Continuous Delivery Pipeline. DevOps is integral to every Value Stream.
DevOps covers five main aspects (‘CALMR’ approach):
- Culture of shared responsibility – DevOps leverages the culture created by adopting the LeanAgile values, principles and practices of the entire framework.
- Automation – DevOps relies heavily on automation to provide speed, consistency, and repeatable processes and environment creation.
- Lean Flow – Teams strive to achieve a state of continuous flow, enabling new features to move quickly from concept to cash. Three primary keys to implementing flow – Visualize and Limit Work in Process. Reduce the batch sizes of work items. Manage queue lengths.
- Measurement – Measure the flow of Value.
- Recover – Enable Low-Risk Releases.
In short, implementing DevOps best practices and workflows helps businesses save time and money, increase software lifecycle predictability, build a corporate culture around innovation and keep motivation levels high.
