The software architect is primarily responsible for the technical quality of the software implementation and ensuring that the software design is suitable for its intended purpose. The technical quality includes aspects such as maintainability, scalability, and adherence to architectural standards. Ensuring that the software design is suitable for its purpose ensures that the system fulfills the necessary requirements effectively. The performance of the software and ensuring it is free of errors are more specific concerns that can be handled by specialized roles like performance engineers and testers, respectively.
