Security: An information system must be secure against unauthorized access.
Robustness: An information system must resist mishandling and negligent operation.
Efficiency: An information system must carry its tasks with the maximum speed and a minimum amount of resources.
Flexibility: Within predictable parameters, an information system must accommodate changes in its environment and in business needs.
Maintainability: When an existing system cannot cope with changes or displays a behavior that was wrong from the start, then it must be repaired.
