What capability is used to achieve a fast delivery process with minimal manual effort?

The capability that leads to a fast delivery process with minimal manual effort is primarily related to automated testing. Automated testing allows teams to run tests on their code quickly and repeatedly without the need for manual testing efforts, which can be time-consuming and prone to human error. This automation not only enhances the speed of the delivery process but also improves the reliability of the software by ensuring that functionality is consistently tested with each iteration.

Continuous Integration, while relevant to streamlining the delivery process, focuses on integrating code changes frequently to detect integration issues early. It does facilitate faster delivery but relies heavily on automated testing to ensure that the integrated code is stable.

Feature toggles allow teams to enable or disable functionality without deploying new code, which helps manage the release of features but does not itself contribute directly to automation in the delivery process.

Dedicated support teams provide assistance after developments are complete, which does not directly enhance the delivery speed or reduce manual effort during the actual delivery process.

Thus, automated testing plays a crucial role in enabling a fast delivery process with minimal manual effort, making it the most appropriate choice in this context.
