What makes value available when it's needed?

The correct answer, which is "Release on demand," refers to the ability to deliver features and updates to customers precisely when they are needed, rather than being constrained by a predetermined release schedule. This approach allows organizations to respond to market demands swiftly, providing value to customers as soon as it is ready and relevant, enhancing customer satisfaction and ensuring that the most current features are available.

In a release-on-demand environment, teams can deploy code into production whenever they choose, enabling them to take advantage of new trends or requirements without delay. This flexibility aligns closely with agile and lean principles by ensuring that the workflow is efficient and responsive to user needs. It empowers product owners and managers to prioritize features based on real-time feedback and market changes, thus maximizing the overall value delivered to the end users.

While the other choices like continuous deployment and DevOps are certainly related concepts that aim to streamline the development and delivery process, they do not specifically encapsulate the ability to release features precisely when they are needed. Continuous deployment focuses on automating the release process, while DevOps emphasizes collaboration between development and operations to improve the delivery pipeline. Infrastructure is essential for supporting these activities but does not directly correlate to the concept of making value available on demand.
