During which phase of an agile approach is an executable program created?

In an agile approach, the implementation phase is where an executable program is created. This phase is crucial because it involves the actual development of the software based on the design specifications and user requirements that were established earlier in the process.

During implementation, the team takes the defined features and user stories and translates them into working code. This is when developers write, compile, and debug the software to produce a functioning version of the program that can be delivered incrementally.

The nature of agile emphasizes iterative development and frequent reassessment, meaning that throughout the implementation phase, the team focuses on producing working software in short iterations, allowing for adjustments based on feedback before the next iteration begins. This approach promotes continuous improvement and ensures that the final product aligns closely with the user's needs.

In contrast, the other phases such as design, testing, and evaluation are critical to the development process but do not result in the creation of executable software. The design phase focuses on planning and defining how the software will operate, testing is concerned with verifying that the software works correctly, and evaluation involves assessing the product's performance and user satisfaction post-implementation.
