This document defines a quality-in-use model composed of three characteristics (which are further subdivided into sub-characteristics) that can influence stakeholders when products or systems are used in a specified context of use. This model is applicable to the entire spectrum of information system and IT service system, including both computer systems in use and software products in use. This document provides a set of quality characteristics for specifying, measuring, evaluating and improving quality-in-use. In this document, because context of use is specified as prerequisite of quality-in-use, context of use is necessary to be re-specified to change prerequisite when a product or service intend to fulfil to context of use changes. The model can be applied, in particular, by those responsible for specifying and evaluating software product quality, such as developers, acquirers, quality assurance and control staff, and independent evaluators. Activities during product development that can benefit from the use of the quality model can include, but are not limited to: — identifying requirements for information system and IT service system in use; — validating the comprehensiveness of a quality-in-use requirements specification; — identifying information system and IT service system design objectives for quality-in-use; — identifying quality-in-use control criteria as part of overall quality assurance; — identifying acceptance criteria for information system and IT service system or information systems; — establishing measures to address the consequences of using products in specified context-of -use; — presenting evaluation items for ethics considerations when using information system and IT service system; — supporting governance of digitalization activities.

This document defines a product quality model, which is applicable to ICT (information and communication technology) products and software products. The product quality model is composed of nine characteristics (which are further subdivided into subcharacteristics) that relate to quality properties of the products. The characteristics and subcharacteristics provide a reference model for the quality of the products to be specified, measured and evaluated. NOTE 1 In this document, a product refers to an ICT product that is part of an information system. ICT product components include subsystems, software, firmware, hardware, data, communication infrastructure, and other elements that are part of the ICT product. This model can be used for requirements specification and evaluation of the target products’ quality throughout their lifecycle by several stakeholders, including developers, acquirers, quality assurance and control staff and independent evaluators. Activities in the product lifecycle that can benefit from the use of this model include: — eliciting and defining product and information system requirements; — validating the comprehensiveness of requirements definition; — identifying product and information system design objectives, and design necessary process for achieving quality; — identifying product and information system testing objectives; — identifying quality control criteria as the part of quality assurance; — identifying acceptance criteria for a product and/or an information system; — establishing measures of product quality characteristics in support of these activities. NOTE 2 Usage of the quality model for measurement is explained in Annex C.

This document provides requirements and guidance on the implementation of DevOps to define, control, and improve software life cycle processes. It applies within an organization or a project to build, package, and deploy software and systems in a secure and reliable way. This document specifies practices to collaborate and communicate effectively in groups including development, operations, and other key stakeholders. This document applies a common framework for software life cycle processes, with well-defined terminology. It contains processes, activities, and tasks that are to be applied to the full life cycle of software systems, products, and services, including conception, development, production, utilization, support, and retirement. It also applies to the acquisition and supply of software systems, whether performed internally or externally to an organization. These life cycle processes are accomplished through the involvement of stakeholders, with the ultimate goal of achieving customer satisfaction. The life cycle processes of this document can be applied concurrently, iteratively, and recursively to a software system and incrementally to its elements. This document applies to software systems, products, and services, and the software portion of any system. Software includes the software portion of firmware. Those aspects of system definition needed to provide the context for software systems, products, and services are included. There is a wide variety of software systems in terms of their purpose, domain of application, complexity, size, novelty, adaptability, quantities, locations, life spans, and evolution. This document describes the processes that comprise the life cycle of software systems. It therefore applies to one-of-a-kind software systems, software systems for wide commercial or public distribution, and customized, adaptable software systems. It also applies to a complete stand-alone software system and to software systems that are embedded and integrated into larger, more complex, and complete systems.

This document defines the quality model of cloud services. The quality model of cloud services is composed of nine characteristics (some of which are further subdivided into subcharacteristics), which provide consistent terminology for specifying, measuring and evaluating cloud services so that the stakeholders, cloud service customer (CSC), cloud service provider (CSP) and cloud service partner (CSN) have a common understanding. Since the quality model in this document is the extension to the existing quality models defined in ISO/IEC 2501n, it can be used with the product quality model, IT service quality model, data quality model, and quality-in-use model according to evaluation purposes. As there are several cloud service categories, this document focuses on the quality model of SaaS (Software as a Service). NOTE Future documents are intended to address PaaS (Platform as a Service) and IaaS (Infrastructure as a Service).

This Handbook provides recommendations for the implementation of an Agile approach in space software projects complying with EN 16603-40 (based on ECSS-E-ST-40) and EN 16602-80 (based on ECSS-Q-ST-80).
This handbook is not an Agile development book, though it provides an Agile reference model based on Scrum and also covers other major Agile methods and techniques. Scrum has been selected as reference because of its widespread application in industry and its flexibility as a development framework to introduce or merge with other Agile methods and techniques. In relation to the EN 16603-40 and EN 16602-80, this handbook does not provide any tailoring of their requirements due to the use of the Agile approach, but demonstrates how compliance towards ECSS can be achieved. This handbook does not cover contractual aspects for this particular engineering approach, although it recognises that considering the approach of fixing cost and schedule and making the scope of functionalities variable, the customer and supplier need to establish specific contractual arrangements. Furthermore, it does not impose a particular finality for the use of Agile, either as a set of team values, project management process, specific techniques or supporting exploration by prototypes.

This document provides guidance for the maintenance of software, based on the maintenance process and its activities and tasks defined in ISO/IEC/IEEE 12207:2017, 6.4.13. Moreover, this document describes the maintenance process in greater detail and establishes definitions for the various types of maintenance. This includes maintenance for multiple software products with the same maintenance resources. “Maintenance” in this document means software maintenance unless otherwise stated. The document does not address the operation of software and the operational functions, e.g. backup, recovery, system administration, which are normally performed by those who operate the software. However, it does include the related disposal process defined in ISO/IEC/IEEE 12207:2017, 6.4.14. This document is written primarily for managers, maintenance organizations, quality managers, users and acquirers of systems containing software. Many of the activities and tasks discussed in this document apply equally to maintenance services, as well as to maintained software products. For example, in a COTS intensive system, maintenance services are performed to sustain the product in operations. While the scope of this document is software maintenance, hardware and hardware costs are important considerations for maintenance.
