4. Survey of Concerns
Does the software solve the problems that have been identified?
We depend on those Business Analysts.
Does the software keep proper care of the data?
Is the data stored durably as appropriate and are there reasonable semantics for the transactions that are needed?
Can the correct audience use the application correctly?
Do we make it convenient for authorized users?
Do we properly deter unauthorized users?
Is it fast enough?
What are the demands for usage by the audience?
Are there real-time requirements?
How do we demonstrate that the software we construct is reliable when used?
How do we identify software failures in production and assure that we can repair them?
