Which development method focuses on releasing small, well-tested code blocks as quickly as possible to bring functionality to the business?

The development method that emphasizes the rapid release of small, well-tested code blocks is Agile. This approach is designed to promote flexibility and continuous improvement, allowing teams to respond swiftly to changing requirements and user feedback. Agile methodologies break down software development into smaller, manageable units called iterations, typically lasting a few weeks, which enables frequent releases of functional software.

By focusing on delivering small functionalities in short cycles, Agile not only speeds up the development process but also allows for regular testing and quality assurance. This means that potential issues can be identified and addressed early in the development process, leading to higher-quality outcomes and a better fit for business needs. Agile cultivates a collaborative environment, encouraging constant communication among team members and stakeholders, which is crucial for aligning the development efforts with the organization's goals.

In contrast, other methods like Waterfall follow a linear and sequential approach, making it less adaptable to changes and potentially delaying the delivery of functional software. The Spiral model incorporates elements of both design and prototyping in stages but is not primarily focused on rapid and frequent releases. While SecDevOps integrates security practices within the Agile DevOps process, it does not singularly focus on the rapid delivery of code like Agile does. Thus, Agile is the most suitable method for quickly
