Who is responsible for the system architecture of a product in Scrum?

In Scrum, the responsibility for the system architecture of a product lies with the Development Team. This is because the Development Team is made up of cross-functional members who possess the necessary skills and expertise to design and implement the architecture as part of the development process. They work collaboratively to ensure that the architecture aligns with the product vision and meets the defined requirements.

The Development Team not only builds the product increment but also makes decisions regarding its architecture, design choices, and technical implementation. This autonomy enables them to adapt the architecture over time as the product evolves and as they gain more insight into technical feasibility and constraints. Ensuring that the architecture is effective and aligned with long-term goals is an integral part of their responsibilities.

In summary, the Development Team's involvement in system architecture is crucial for effective collaboration, product quality, and the ability to respond to changing requirements throughout the Scrum framework.
