What is meant by quality in software?

Quality software is reasonably bug or defect free, delivered on time and within budget, meets requirements and/or expectations, and is maintainable. ISO 8402-1986 standard defines quality as “the totality of features and characteristics of a product or service that bears its ability to satisfy stated or implied needs.”

What are qualities of good software?

It can be measured on:

• Budget.
• Usability.
• Efficiency.
• Correctness.
• Functionality.
• Dependability.
• Security.
• Safety.

Why the quality of software is important?

Software quality drives predictability. Do it once and do it right, and there will be less re-work, less variation in productivity and better performance overall. Products get delivered on time, and they get built more productively. Poor quality is much more difficult to manage.

Why is software quality important to security?

Software quality is very important because software errors pose a constant threat to information systems. Flaws in software can also create security vulnerabilities that open networks to intruders. Keeping up to date software with proper security features will help prevent hackers.

What is high quality software?

Software is considered to be of a high quality when it meets or exceeds customer expectations and earns customer satisfaction. To break this down further, quality signifies more than just usability, robustness, efficiency, reliability, maintainability, portability, and reusability.
