In which phase of an agile approach are program goals modified based on client feedback?

In the agile approach, the phase where program goals are modified based on client feedback is typically the implementation phase. During this stage, the development team actively engages with clients to gather feedback on the product as it's being developed. This feedback can lead to adjustments in the program goals, ensuring that the final product closely aligns with client expectations and needs.

Implementation is characterized by iterative development cycles where features are built, demonstrated, and refined based on user input. This continuous incorporation of feedback allows for flexibility in adapting to changes and improving the product incrementally. By incorporating feedback during this stage, the development process remains responsive to real-world uses and client requirements, promoting a more effective final outcome.

In contrast, other phases such as testing, analysis, and design focus on different aspects of the project. Testing primarily assesses the product's functionality and ensures that it meets quality standards, while analysis focuses on understanding requirements and defining what the project should achieve before development begins. The design phase involves creating the architecture and user interfaces based on gathered requirements, but does not specifically address the adaptation of goals in response to client feedback as effectively as the implementation phase does.
