Standards Development

Scope

The scope of the proposed standard is a newly additional part (Part 3) of the existing standard as the revision of quality model framework content. Specifically, the proposed Part 3 of ISO/IEC 25010 will contain a quality in use model in systems and software engineering.

The proposed standard ISO/IEC 25010-3, which is a part of multipart standard ISO/IEC 25010 which extends and replaces ISO/IEC 25010: 2011. ISO/IEC 25010:2011 was intended to be used as a reference for quality model framework and quality models as the framework applied.

ISO/IEC 25010-3 provides the quality in use model to following intended readers of this document;

a) acquirers: evaluate if the system/software products/data fulfils their value proposition, i.e., meets the expected quality,

b) specifiers: specify user needs and/or user requirements

c) developers: design, implement, and test the system/software products/data to ensure that it meets the expected quality,

d) evaluaters: verify and validate that the system/software products/data meets the expected quality,

e) project managers: plan, monitor, and control the achievement of the expected quality, and

f) independent evaluators: evaluate the system/software products/data with the objective criteria.

ISO/IEC 25010 consists of following other two parts,

- ISO/IEC 25010 Systems and software engineering Systems and software Quality Requirements and Evaluation (SQuaRE) System and software quality models Part 1: Quality models overview and usage

- ISO/IEC 25010 Systems and software engineering Systems and software Quality Requirements and Evaluation (SQuaRE) System and software quality models Part 2: Product quality model

Purpose

Information systems and ICT products are increasingly used to perform a wide variety of organizational functions and personal activities. The quality of these products and systems enable and impact various business, regulatory and information technology stakeholders including direct and indirect users, developers, testers, maintainers, acquirers, independent evaluators, system integrators, implementers, operations engineers, architects, trainers, business owners, auditors, managers, and the society at large. High-quality information systems and ICT products are hence essential to provide value, and avoid potential negative consequences, for the stakeholders.

Realization of goals and objectives like personally satisfaction, business success and human safety relies on a structured approach to ensure efficiency, effectiveness, satisfaction, risk reduction and resilience while considering critical aspects like health, safety and environment, data privacy and cyber security, as well customer and/or user experience.

Globalization, Consumerization and Industry Convergence has also led to newer needs like Business Agility for which focus on Efficiency, Effectiveness, Predictability, Adaptability, Risk Reduction, Sustainability, and Compliance of information systems and associated ICT products and data has become even more critical.

The complexity of information systems has also increased exponentially with the advent of contemporary digital technologies like Internet of Things, Big Data, Analytics, Distributes Ledger Technology, Robotic Process Automation, Cognitive Machine Learning, Social Media, Mobility, Cloud Infrastructure, Software as a Service, Platform as a Service, Function as a Service (server less computing), and Green IT. This has also led to focus on more and more non-functional requirements and qualities that are critical to modern information systems

Comprehensive specification and evaluation of the quality of information systems, ICT products and their components in accordance with stakeholders' goals and objectives are key factors in ensuring value to stakeholders. This includes qualities related to the ICT product and its components like FORM 4 – New Work Item Proposal Version 06/2018 software and data, as well as the impact the overall information system has on its stakeholders. It is important that we define quality models that provide a structured approach in which quality characteristics of information systems, ICT products and their components can be specified, measured, and evaluated in a way that is commonly understood by all stakeholders, and whenever possible provide specific qualitative feedback and validated or widely accepted quantitative measures that are relevant to a given stakeholder involved in direct or indirect use, evaluation, selection, development, system integration, verification, validation, customization, implementation, maintenance, operations, and management of ICT systems (systems of systems), information systems, ICT products and their components in a given context of use.

This International Standard clarifies structure of the quality in use as a tree structured model and defines quality characteristics and subcharacteristics composing the model. This International Standard is useful to specify quality requirements for use from multiple point of views of users. This International Standard is also useful to evaluate and estimate influence on users by use of the system/software product.
