BS EN ISO 25003:2019 is a technical standard that provides guidelines for evaluating software products and systems for quality characteristics. This standard focuses on the measurement of quality in terms of functional suitability, performance efficiency, compatibility, usability, reliability, security, maintainability, and portability.
Functional Suitability
Functional suitability refers to how well a software product or system meets the specified functional requirements. BS EN ISO 25003:2019 defines criteria and methods for measuring the extent to which these requirements are satisfied. It also addresses the suitability of functional features and their combinations, as well as any unforeseen functionality included in the software.
Performance Efficiency
Performance efficiency measures how well a software product or system performs its functions under stated conditions. BS EN ISO 25003:2019 provides guidance on assessing various parameters, such as response time, throughput, resource utilization, and capacity. It also covers scalability, which is the ability of the software to handle increasing workloads without a significant decrease in performance.
Compatibility, Usability, Reliability, Security, Maintainability, and Portability
These quality characteristics are crucial for ensuring the overall effectiveness and reliability of a software product or system.
Compatibility: This aspect refers to the software's ability to coexist with other systems, components, or products without any adverse effects.
Usability: Usability assesses the user-friendliness and ease of use of the software. It involves factors such as learnability, operability, and user satisfaction.
Reliability: Reliability relates to the software's capability to perform its intended functions without failure over a specific period and under defined conditions.
Security: Security focuses on protecting the software from unauthorized access, use, disclosure, disruption, modification, or destruction.
Maintainability: Maintainability refers to the ease with which modifications or corrections can be made to the software without causing adverse effects.
Portability: Portability measures the ability of the software to be transferred from one environment to another without any loss of functionality or performance.
In conclusion, BS EN ISO 25003:2019 provides valuable guidelines for evaluating the quality characteristics of software products and systems. It ensures that these products meet functional requirements, perform efficiently, and possess the necessary compatibility, usability, reliability, security, maintainability, and portability. Adhering to this standard can help organizations deliver high-quality software products that meet customer expectations and industry standards.
