Quality attributes for Software Product Flashcards
What is Quality attributes ?
Also known as Non functional requirements
Describes overall characteristics that a software product should have.
Which are performance, reliability, and usability.
Three examples of Performance for Software Product
- How much time does it take for a system to respond to user input.
- Measure workload processing capacity of system
- Does the system has ability to handle increased load
Three examples for Reliability for Software Product
- System’s uptime and accessibility
- System remains functional despite component failures
- Measure system’s ability to recover from failures
Three examples of usability for Software Product
- User Interface responsiveness
- How easily a user can learn and use software
- Ensures software is usable by individuals with disabilities
3 characteristics of ISO 91261/ ISO 25000 external software quality standards
→ Functionality - how well a system meets specific requirements and performs its intended functions efficiently.
→ Reliability - how it maintains performance.
Involves fault tolerance, error handling, stability, ensure consistent and accurate results without unexpected failures.
→ Portability - how easily a software can be transferred between different environments without modifications.
Platform independency, adapt to various operating systems
Compatibility to diverse hardware configurations
How 2 types of quality checking are carried at in early stages of a development project
1) Document review
examine project documents for accuracy and completeness.
Team members provide feedback and make corrections.
2) Inspection
Detail examination of project artefact
Participants discuss findings in structured meeting and prioritize defect resolution.
Follow-up inspections conducted to ensure all issues are addressed.
