This document provides the framework for quality requirements for systems, software products and 
data, which includes concept of the quality requirements, and requirements and recommendations for 
the processes and methods to elicit, define, use and govern them. Intended readers of this document 
include, but are not limited to:
— acquirers: evaluate if the system/software products/data fulfills their value proposition, i.e., meets 
the expected quality,
— developers: design, implement and test the system/software products/data to ensure that it meets 
the expected quality,
— testers: verify and validate that the system/software products/data meets the expected quality,
— project managers: plan, monitor and control the achievement of the expected quality, and
— independent evaluators: evaluate the system/software products/data with the objective criteria.
This document complies with the technical processes defined in ISO/IEC/IEEE 15288, which are 
relevant for elicitation of stakeholders’ quality needs and for defining, analyzing and maintaining 
quality requirements. In this document, the quality models in ISO/IEC 25010 and ISO/IEC 25012 are 
used to categorize quality requirements and to provide a basis for quantifying them in terms of quality 
measures in the quality measure division of ISO/IEC 2502n.
This document does not cover specification of the other requirements (such as functional requirements, 
process requirements, etc.), and prescribes neither any specific quality measure nor any specific 
development process.nd edition 2019-08 Systems and software engineering — Systems and software quality requirements and evaluation (SQuaRE) — Quality requirements framework Reference number ISO/IEC 25030:2019(E) ？ ISO/IEC 2019 ISO/IEC 25030:2019(E) COPYRIGHT PROTECTED DOCUMENT ？ ISO/IEC 2019 All rights reserved.
