What should the Development Team plan for each Sprint regarding architecture?

The Development Team should plan time to discuss architecture related to the planned features in each Sprint. This approach ensures that the architecture evolves as the product develops and aligns with the current needs and goals of the Sprint.

Effective software development often involves ongoing refinement and adaptation of architecture as new insights are gained, features are added, or technical constraints are uncovered. By dedicating time for architectural discussions, the team can make informed decisions about how to implement features while maintaining the integrity and scalability of the system architecture.

Additionally, planning for architecture in this way promotes collaboration within the team, allowing members to bring their expertise to the conversation and consider different perspectives. This collaborative effort helps in identifying potential architectural changes early, thereby reducing risks and improving the overall quality of the final product.

In this context, the other options reflect less effective approaches. A complete overhaul of existing architecture would be disruptive and unnecessary unless absolutely required, while a review without actual planning does not provide a pathway to making meaningful architectural adjustments. Finally, the notion that no planning is necessary because architecture is fixed ignores the reality that software systems must be adaptable to remain effective in the face of changing requirements and environments.
