3.1 Glossary

3.2 Non-Functional Requirements

Non-functional requirements are requirements across the system

High-priority

1. The system must be well-tested. The test suites consisting of unit tests and integration tests must have a 70-80% code coverage.

2. The system must be intuitive to use and user-friendly.

3. The system must protect privacy so that only the authorized person can access his/her data

4. The system must make sure users data are not lost in the event of accidents (maintain data redundancy)

5. The system must be compatible with major browsers (Chrome, Firefox, Opera, Safari, Edge, etc).

6. Each page of the system’s page should load under 2000 ms and each server response time should be under 200ms (https://developers.google.com/speed/docs/insights/Server says server response time should be under 200ms)

Further research required

• The system must be able to handle bill or statement documents of up to X MB. (currently we don’t know what’s the average file size for bills)

• The system must safeguard against the most common vulnerability attacks performed by penetration tests. (requires research)

• Inactivity timeouts? (Functional)

Low-priority

1. The system should be scalable (more users shouldn’t slow down the app)

2. The system should be responsive

3. user can upload several bills at one time to save time

4. the system must be able to handle pdf file format

5. the system should be able to handle jpeg format

6. the system should be able to additional image formats not defined under supported formats. (png, gif, bmp)

Further research required

• Data requirements e.g. size, volatility, persistency etc.,

• Environment requirements e.g. technical environment in which system would operate or need to be compatible with

• Accessibility, Capacity, Compliance with regulations, Documentation, Disaster recovery,

• Efficiency, Extensibility, Fault tolerance, Interoperability, Maintainability, Privacy, Portability, Quality, Reliability, Response time, Robustness, Scalability, Security, Stability, Testability, and more...

3. I want to recognize (or prompt from the user for) the logo from the documents.

4. I want to recognize (or prompt from the user for) account no from the documents (not sure if every bill has a bill no OR reference no. Even if they have, it might not be obvious to the user) (Have a list of bill reference no.? -> Kenan’s POSB)
