ISO/IEC 25051:2014 is a standard in the field of software engineering that specifies quality requirements and provides testing guidelines for Ready-to-Use Software Products (RUSP). This international standard is part of the SQuaRE (Systems and software Quality Requirements and Evaluation) series, which focuses on defining and assessing software and system quality. The complete English version comprises 38 pages and addresses various aspects such as functional suitability, reliability, performance efficiency, usability, security, compatibility, maintainability, and portability. It is commonly used by developers, testers, and quality assurance professionals to ensure that commercial off-the-shelf software meets specified quality benchmarks before deployment.

In the context of network systems integration engineering, this standard plays a critical role in selecting and integrating RUSPs into larger systems. For instance, when integrating software components into a networked environment, adherence to ISO/IEC 25051 ensures that the products are reliable, secure, and compatible with existing infrastructure. This reduces risks associated with system failures, security breaches, and interoperability issues.

The document is often available as an internet resource, with platforms like CSDN offering downloads for professionals and students in computer science and engineering fields. Accessing such resources helps in implementing standardized testing procedures, thereby enhancing the overall quality and efficiency of software products in network system integration projects.
