Tasks:

1. Identify the potential unexpected situations or errors that can occur in the system.
2. Design a comprehensive set of error handling mechanisms to gracefully handle these situations.
3. Implement robust exception handling and error logging mechanisms to capture and record errors that occur during system execution.
4. Customise error messages to provide clear and informative feedback to users when unexpected errors occur.
5. Implement appropriate error fallback mechanisms to guide users to alternative actions or recovery steps when errors happen.
6. Test the error handling and fallback mechanisms with different scenarios and inputs to ensure they function as intended.
7. Consider providing error codes or unique identifiers for logged errors to facilitate troubleshooting and debugging.
8. Implement user-friendly error pages or views that display helpful information and instructions for users when errors occur.
9. Ensure that the error handling mechanisms do not expose sensitive information or compromise system security.
10. Consider providing error reporting functionality for users to report errors they encounter, assisting in identifying and resolving issues.
11. Regularly review and analyse error logs to identify recurring issues and prioritize bug fixes or system improvements.
12. Document the error handling mechanisms, including the error messages and fallback procedures, for future reference and maintenance.
