Systems and software engineering — Systems and software assurance — Part 3: System integrity levels

This document specifies the concept of integrity levels with the corresponding integrity level requirements for achieving the integrity levels. Requirements and recommended methods are provided for defining and using integrity levels and their corresponding integrity level requirements. This document covers systems, software products, and their elements, as well as relevant external dependences. This document is applicable to systems and software and is intended for use by: a) definers of integrity levels such as industry and professional organizations, standards organizations, and government agencies; b) users of integrity levels such as developers and maintainers, suppliers and acquirers, system or software users, assessors of systems or software and administrative and technical support staff of systems and/or software products. One important use of integrity levels is by suppliers and acquirers in agreements, for example, to aid in assuring safety, financial, or security characteristics of a delivered system or product. This document does not prescribe a specific set of integrity levels or their integrity level requirements. In addition, it does not prescribe the way in which integrity level use is integrated with the overall system or software engineering life cycle processes. It does, however, provide an example of use of this document in Annex A.

Systems and software engineering — Engineering and management of websites for systems, software and services information

This document defines system engineering and management requirements for the life cycle of websites, including strategy, design, engineering, testing and validation, and management and sustainment for intranet and extranet environments. This document applies to those using web technology to present information and communications technology (ICT) information, such as information for users of systems and services, plans and reports for systems and software engineering projects, and documentation of policies, plans, and procedures for IT service management. This document provides requirements for website owners and website providers, managers responsible for establishing guidelines for website development and operations, website engineers, designers, developers, and operations and maintenance staff, who can be external or internal to the website owner's organization. It applies to websites for public access and for limited access, such as for users, customers, and subscribers seeking information on IT systems, products and services. The requirements and recommendations in this document address the following aspects of usability of informational websites and ease of maintenance of managed website operations: a) locating relevant and timely information; b) applying information security management; c) facilitating accessibility and ease of use; d) providing for consistent and efficient development and maintenance practices. This document is not particularly applicable to websites used primarily for marketing or sales, to deliver instructional material (tutorials), or to provide graphical user interfaces (GUI) for business or consumer transactional application processing. However, this document can provide useful insights for managing such sites. This document does not address vendor and product considerations for website engineering and management. This document does not include specifications for application development tools, programming and scripting languages used for websites, metadata tags, or protocols for network communications. It does not address tools or systems used for management or storage of information content (data, documents) that can be presented on websites. This document does not address the design and architecture of software and systems supporting the Internet.

This document provides requirements and guidance on the application of system and software engineering processes to systems for epidemic prevention and control. This document provides guidance that can be employed for adopting and applying system and software life cycle processes within an organization or a project in an epidemic emergency. It includes system of systems considerations in the context of epidemic emergency. This document applies to acquisition, supply, development, operation, maintenance, and disposal (whether performed internally or externally to an organization) of system or system of systems in an epidemic emergency. Many of the requirements and recommendations in this document are also applicable to other systems developed rapidly to respond to emergency conditions affecting the public.

Systems and software engineering — System life cycle processes

This document establishes a common framework of process descriptions for describing the life cycle of systems created by humans, defining a set of processes and associated terminology from an engineering viewpoint. These processes can be applied to systems of interest, their system elements, and to systems of systems. Selected sets of these processes can be applied throughout the stages of a system's life cycle. This is accomplished through the involvement of stakeholders, with the ultimate goal of achieving customer satisfaction. This document defines a set of processes to facilitate system development and information exchange among acquirers, suppliers, and other stakeholders in the life cycle of a system. This document specifies processes that support the definition, control, and improvement of the system life cycle processes used within an organization or a project. Organizations and projects can use these processes when acquiring and supplying systems. This document applies to organizations in their roles as both acquirers and suppliers. This document applies to the full life cycle of systems, including conception, development, production, utilization, support and retirement of systems, and to the acquisition and supply of systems, whether performed internally or externally to an organization. The life cycle processes of this document can be applied iteratively and concurrently to a system and recursively to the system elements. This document applies to one-of-a-kind systems, mass-produced systems, and customised, adaptable systems. It also applies to a complete stand-alone system and to systems that are embedded and integrated into larger more complex and complete systems. This document does not prescribe a specific system life cycle model, development methodology, method, modelling approach or technique. This document does not detail information items in terms of name, format, explicit content, and recording media. ISO/IEC/IEEE 15289 addresses the content for life cycle process information items (documentation).

Systems and Software engineering — Methods and tools for model-based systems and software engineering

This document deals with the tool capabilities and methods for model-based systems and software engineering (MBSSE). This document: — specifies a reference model for the overall structure and processes of MBSSE-specific processes, and describes how the components of the reference model fit together; — specifies interrelationships between the components of the reference model; — specifies MBSSE-specific processes for model-based systems and software engineering; the processes are described in terms of purpose, inputs, outcomes and tasks; — specifies methods to support the defined tasks of each process; — specifies tool capabilities to automate or semi-automate tasks or methods. This document does not bring any additional life cycle processes for system and software but specifies an MBSSE reference model considered as activities, not only from the life cycle perspectives of systems engineering problem solving and the system-of-interest evolution, but also from the cognitive perspectives of modelling and model management, which can sustain and facilitate the system and software life cycle processes during digital transformation and in the digital age. The processes defined in this document are applicable for a single project, as well as for an organization performing multiple projects or an enterprise. These processes are applicable for managing and performing the systems and software engineering activities based on models within any stage in the life cycle of a system-of-interest.
