Which of the following is NOT typically a focus during the integration process?

During the integration process, the primary focus is often on ensuring that different systems work together seamlessly. This includes critical activities such as data mapping, user interface design, and user authentication.

Data mapping is essential as it involves defining how data from one system will translate into another system, ensuring consistency and accuracy. User interface design plays a key role as it affects how users interact with the integrated system, ensuring that the end-user experience is smooth and intuitive.

User authentication is equally important, as it ensures that the right individuals have access to the integrated system and that security protocols are maintained.

Performance testing, while crucial in the overall application life cycle, tends to take place after the integration is complete rather than during the actual integration phase. It focuses on assessing how well the application performs under various conditions and is not primarily about bringing disparate systems together. Therefore, the focus during integration is more about the functional aspects rather than performance metrics, making it the correct answer in this context.
