ISO/IEC 25050:2014

ISO/IEC 25050:2014, also known as Software Engineering - Systems and Software Quality Requirements and Evaluation (SQuaRE) - Guide to Systems and Software Quality Requirements and Evaluation (SQuaRE), is an international standard that provides guidance on quality requirements and evaluation for systems and software. It was developed by the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC) to ensure the quality of systems and software throughout their lifecycle.

Key Concepts in ISO/IEC 25050:2014

ISO/IEC 25050:2014 introduces several key concepts that are essential to understanding and applying the standard. These concepts include:

Quality requirement: A statement of a need, constraint, or expectation related to the quality of a system or software.

Quality attribute: A measurable or testable property of a system or software that contributes to its overall quality.

Evaluation: The systematic determination and assessment of the extent to which a system or software fulfills defined quality requirements.

Measurement: The process of assigning numbers or symbols to quality attributes to represent their magnitude according to certain rules.

Indicator: A simplified representation of a measurement result that provides information about a specific quality attribute.

Importance of ISO/IEC 25050:2014

ISO/IEC 25050:2014 plays a crucial role in ensuring the quality of systems and software. By providing comprehensive guidance on quality requirements and evaluation, it helps organizations define, prioritize, and assess the quality attributes that are critical to their systems or software. This standard enables organizations to develop a systematic approach to quality management, resulting in improved customer satisfaction, reduced risks, and increased efficiency.

Moreover, ISO/IEC 25050:2014 promotes interoperability and compatibility between different systems and software by providing a common language and framework for quality evaluation. It facilitates collaboration among stakeholders, such as developers, users, and regulatory bodies, by offering a shared understanding of quality requirements and metrics. By adhering to this standard, organizations can enhance their reputation, build trust with customers, and gain a competitive advantage in the global market.


ISO/IEC 25050:2014 is a comprehensive international standard that guides organizations in defining, evaluating, and improving the quality of their systems and software. By implementing the principles and concepts outlined in this standard, organizations can ensure that their products meet the expectations and requirements of their stakeholders. As technology continues to advance rapidly, this standard provides a valuable framework for maintaining and enhancing the quality of systems and software in an ever-changing environment.
