As a result of balloting in ISO, the statement of scope was modified as follows: "This standard describes a process for the management of risk during systems or software acquisition, supply, development, operations, and maintenance. P - IEEE Draft International Standard - Systems and Software Engineering -- Systems and Software Assurance -- Part 4: Assurance in the Life Cycle This document provides guidance and recommendations for assurance of a selected claim about the system-of-interest by achieving the claim and showing the achievement.
These relations are demonstrated by means of mapping tables that show relationships between activities and tasks, and process outcomes. This mapping assists users of the edition to transition to using the edition. These process activities and tasks can be applied iteratively. P - Software Engineering - Software Life Cycle Processes - Maintenance This standard describes an iterative process for managing and executing software maintenance activities.
Use of this standard is not restricted by size, complexity, criticality, or application of the software product. This standard uses a process model to discuss and depict aspects of software maintenance.
The criteria established apply to both the planning of maintenance for software while under development, as well as the planning and execution of software maintenance activities for existing software products. Ideally, maintenance planning should begin during planning for software development. This International Standard provides the framework within which generic and specific software maintenance plans may be executed, evaluated, and tailored to the maintenance scope and magnitude of given software products.
This International Standard provides the framework, precise terminology, and processes to allow the consistent application of technology tools, techniques, and methods to software maintenance. This International Standard provides requirements and guidance for the maintenance of software. This standard defines the activities and tasks of software maintenance, and provides maintenance planning requirements.
It does not address the operation of software and the operational functions, e. It gives requirements and recommendations for the description of processes by identifying elements and rules for their formulation.
It characterizes the following elements of process description: - Title; - Purpose; - Outcomes; - Activities; - Tasks; - Outputs, including?
It uses unit design and unit implementation information, in addition to unit requirements, to determine the completeness of the testing. The testing process described composed of a hierarchy of phases, activities, and tasks and defines a minimum set of tasks for each activity. The standard can be applied to the unit testing of any digital computer software or firmware and to the testing of both newly developed and modified units.
The software engineering concepts and testing assumption on which this standard approach is based and guidance and resource information to assist with the implementation and usage of the standard unit testing approach are provided in appendixes. Thus this standard provides industry a basis for software practices that would be usable for both national and international business. This standard is intended to guide the development of systems for commercial, government, military, and space applications.
The information applies to a project within an enterprise that is responsible for developing a product design and establishing the life cycle infrastructure needed to provide for life cycle sustainment. This International Standard also establishes definitions for the various types of maintenance. This International Standard provides guidance that applies to planning, execution and control, review and evaluation, and closure of the Maintenance Process.
The scope of this International Standard includes maintenance for multiple software products with the same maintenance resources. This standard establishes a common framework for describing the life cycle of systems created by humans. It defines a set of processes and associated terminology. These processes can be applied at any level in the hierarchy of a system?
This is accomplished through the involvement of all interested parties with the ultimate goal of achieving customer satisfaction. In addition, the requirements for the systems engineering process and its application throughout the product life cycle are specified. The focus of this standard is on engineering activities necessary to guide product development while ensuring that the product is properly designed to make it affordable to produce, own, operate, maintain, and eventually to dispose of, without undue risk to health or the environment.
This International Standard establishes a common framework for software life cycle processes, with well-defined terminology, that can be referenced by the software industry.
It applies to the acquisition of systems and software products and services, to the supply, development, operation, maintenance, and disposal of software products and the software portion of a system, whether performed internally or externally to an organization.
Those aspects of system definition needed to provide the context for software products and services are included. Software includes the software portion of firmware. This International Standard establishes a common process framework for describing the life cycle of man-made systems.
It defines a set of processes and associated terminology for the full life cycle, including conception, development, production, utilization, support and retirement. This standard also supports the definition, control, assessment, and improvement of these processes. These processes can be applied concurrently, iteratively, and recursively to a system and its elements throughout the life cycle of a system.
The process is described through a model that defines the activities of the measurement process that are required to adequately specify what measurement information is required, how the measures and analysis results are to be applied, and how to determine if the analysis results are valid. The measurement process is flexible, tailorable, and adaptable to the needs of different users.
This International Standard identifies a process that supports defining a suitable set of measures that address specific information needs.
It identifies the activities and tasks that are necessary to successfully identify, define, select, apply, and improve measurement within an overall project or organizational measurement structure.
It also provides definitions for commonly used measurement terms. The discussion and advice are intended to aid in the preparation of the normative content of project management plans. It places requirements on and recommends methods for defining and using integrity levels and their integrity level requirements, including the assignment of integrity levels to systems, software products, their elements, and relevant external dependencies.
It further provides guidance on life cycle model use by domains, disciplines and specialties. An assurance case includes a top-level claim for a property of a system or product or set of claims , systematic argumentation regarding this claim, and the evidence and explicit assumptions that underlie this argumentation. Arguing through multiple levels of subordinate claims, this structured argumentation connects the top-level claim to the evidence and assumptions.
Assurance cases are generally developed to support claims in areas such as safety, reliability, maintainability, human factors, operability, and security, although these assurance cases are often called by more specific names, e. Likewise, it places no requirements on the means of physical implementation of the data, including no requirements for redundancy or co-location. An increasing number of international, national and industry standards describe process models.
These models are developed for a range of purposes including process implementation and assessment. The terms and descriptions used in such models vary in format, content and level of prescription. This International Standard unifies technical and management requirements and guidance from several of these sources to specify the requirements for the content of a SEMP and to provide a common SEMP format.
It defines the construct of a good requirement, provides attributes and characteristics of requirements, and discusses the iterative and recursive application of requirements processes throughout the life cycle. Information items applicable to the engineering of requirements and their content are defined.
Software testing? It supports dynamic testing, functional and non-functional testing, manual and automated testing, and scripted and unscripted testing. Risk-based testing is a common industry approach to strategizing and managing testing. Risk-based testing allows testing to be prioritized and focused on the most important features and functions.
Annex A contains outlines of the contents of each document. Annex C contains an overview of the examples. Annexes D to S contain examples of the application of the templates. Annex T provides mappings to existing standards.
