Explanation
The BA should recommend to gather more information from the individuals who had errors when they attempted to sign on, as this would help to identify and resolve the root cause of the problem. The BA could use techniques such as interviews, surveys, or observation to collect feedback from the affected users, and to understand their needs, expectations, and challenges. The BA could also analyze the system event log to find out the details and frequency of the errors, and to determine if they are related to the user's behavior, the system's design, or the environment's conditions. By gathering more information, the BA could propose and implement appropriate solutions to improve the overall performance of the pilot application. The other options are not the best recommendations for improving the performance, as they may not address the underlying problem, or may introduce new risks or issues. For example, sending a reminder of the user ID and password may not help if the users already know them, or may compromise the security of the system. Automating the login process may not be feasible or desirable, as it may require significant changes to the system or the user's preferences. Extending the pilot to more people may not improve the performance, but may worsen it, as more users may encounter the same errors or create more workload for the system.
