Study Notes

Non-Functional Requirements (NFRs)

Flexibility

It should be possible to add new delivery options by developing and "plugging in" the required functionality.

Maintainability

A regression test procedure should allow complete re-testing within 2 business days.

Scalability

The system should be able to expand processing capabilities to support business growth without affecting availability.

Verifiability

The maximum number of test cases for any particular source code module should be 20.

Interoperability

The system must be able to interface with any HTML browser.

Portability

The system should be able to run in different environments, such as business offices or manufacturing assembly plants.

Reusability

The payment subsystem design is based on the payment module from the ALPHA product line.

Correctness

Deals with the extent to which the software design and implementation conform to the stated requirements, such as time limits and effort constraints.

Safety

The system should not operate under hazardous conditions, such as temperatures below 4°C.

Expandability

The system should be designed to allow for future additions, such as new user buttons and banking services.

Manageability

Administrator tools should be available to support software modification during development and maintenance periods.

Availability

The system should be available at least 99.5% of the time during "normal operating times" and at least 99.95% available during peak hours.

Efficiency

The system should handle capacity, throughput, and response time efficiently, such as downloading new rate parameters within 10 minutes.

Integrity

The system should ensure data accuracy, authenticity, and prevent corruption, with regular checks for inconsistencies.

Reliability

The system should consistently perform specified functions without failure, with a maximum of 10 claim assignments out of 5000 being "unassigned" due to system failures.

Survivability

The system should continue to function and recover in the presence of system failures, with default values specified for policy statement parameters.

Usability

The system should be easy to learn, operate, and prepare inputs, with intuitive interaction and interpretation of outputs.
