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.

It defines a set of processes and associated terminology. This is accomplished through the involvement of all interested parties, with the ultimate goal of achieving customer satisfaction. Scope: This International Standard establishes a common framework of process descriptions for describing the life cycle of systems created by humans.
It defines a set of processes and associated terminology from an engineering viewpoint. These processes can be applied at any level in the hierarchy of a systems structure. This is accomplished through the involvement of all stakeholders, with the ultimate goal of achieving customer satisfaction. This International Standard also provides 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 International Standard concerns those systems that are man-made and may be configured with one or more of the following system elements: hardware, software, data, humans, processes e.
The two standards are harmonized for concurrent use on a single project or in a single organization. Purpose: The purpose of this International Standard is to provide a defined set of processes to facilitate communication among acquirers, suppliers and other stakeholders in the life cycle of a system.
This International Standard applies to organizations in their roles as both acquirers and suppliers. It can be used by a single organization in a self-imposed mode or in a multi-party situation. Parties can be from the same organization or from different organizations and the situation can range from an informal agreement to a formal contract. The processes in this International Standard can be used as a basis for establishing business environments, e.
Annex A provides normative direction regarding the tailoring of these system life cycle processes.
