ISO 25000: quality in software engineering
Assess your software's quality, position it in the market and give your clients a reliable criterion for choosing it.
What is ISO 25000?
SQuaRE: software quality requirements and evaluation
Software is a fundamental tool in any activity, and its quality has become a key criterion when choosing products.
ISO/IEC 25000 (SQuaRE – Software Product Quality Requirements and Evaluation) sets criteria for specifying quality requirements, their metrics and their evaluation.
It includes a quality model that connects what the client means by quality with the attributes of the development process.
Quality model
The eight characteristics of quality software
Performance efficiency
Time behavior and resource utilization.
Compatibility
Coexistence and interoperability with other systems.
Reliability
Maturity, availability, fault tolerance and recoverability.
Usability
Learnability and operability, user error protection, aesthetics and accessibility.
Security
Confidentiality, integrity, accountability, authenticity and non-repudiation.
Maintainability
Modularity, reusability, analyzability, modifiability and testability.
Portability
Installability, replaceability and adaptability to other environments.
